Potassium supplements: what matters
Potassium supplements add potassium in a capsule, tablet, gummy, liquid, or powder. Potassium is needed for normal nerve signaling, muscle contraction, fluid balance, and normal cell function. Whether a product is useful depends less on its headline number or format than on four practical questions: how much **elemental potassium** it actually provides, whether that amount is appropriate for the intended use, whether the directions reduce dosing mistakes, and whether the safety and quality claims can be checked.
The label should distinguish elemental potassium from the weight of potassium citrate, potassium chloride, potassium gluconate, potassium bicarbonate, or another compound. For example, a claim such as “1,000 mg potassium citrate” does not necessarily mean 1,000 mg potassium. A strong label states the elemental amount per serving, identifies the serving size, gives the daily directions, and makes clear whether a capsule, two gummies, or a scoop supplies that amount. Compound weight, per-container quantity, and a large “high potency” number can otherwise make products look comparable when they are not.
Serving design matters particularly with bulk powders and liquids. A measured scoop or tablespoon can be less precise than a capsule, and a small measuring error can materially change potassium intake. Look for a clearly defined serving, dilution volume where relevant, water and food directions, storage instructions, and a stated maximum. A product should not rely only on a generic “ask a doctor” warning. Useful information identifies kidney disease or reduced potassium excretion, heart failure, adrenal disease, diabetes or other relevant conditions, potassium-raising medicines, and symptoms that require medical attention.
A simple formula can make total intake easier to understand. Multi-electrolyte products and gummies should disclose potassium, sodium, magnesium, calcium, chloride, vitamins, sweeteners, botanicals, excipients, and allergens separately. “Sugar-free,” “vegan,” “third-party tested,” “GMP,” and “made in the USA” are not, by themselves, proof of elemental-potassium potency or contaminant control. Buyers should also check lot number and expiration information and look for a current, batch-matched certificate of analysis. A useful report names the purchased lot, laboratory, date, methods, potassium assay, pass limits, and testing for relevant contaminants such as toxic elements and microbiological contamination. Laboratory accreditation should cover the relevant work, not merely be mentioned in marketing.
For independent finished-product verification, the exact product should be currently listed in a credible registry such as USP Verified, NSF Certified Dietary Supplements, NSF Certified for Sport, Informed Sport, or Informed Choice, when applicable. Certification of a facility, brand, or ingredient is not the same as certification of the finished product. Quality claims should also be considered alongside the responsible manufacturer’s identity, contact details, lot and expiration details, manufacturing controls, recalls, warning letters, and adverse-event or regulatory history.
Packaging evidence is more limited in this category. A lower-waste claim should be supported by packaging specifications, recycled content, recyclability information, refill options, or responsible-sourcing documentation. A pouch or bulk container may reduce repeated purchases, but that alone does not establish a lower environmental footprint.
Across the supplied reviews, people with chronic kidney disease, reduced potassium excretion, known high blood potassium, heart failure, adrenal insufficiency, significant liver disease, or diabetes-related potassium-handling concerns are repeatedly told to seek clinician guidance. The same applies to people taking ACE inhibitors, ARBs, potassium-sparing diuretics such as spironolactone, amiloride, or triamterene, potassium-containing medicines, trimethoprim-containing medicines, or potassium salt substitutes. Excess potassium can cause weakness, palpitations, paralysis, and dangerous heart-rhythm changes. These products should not be used to self-treat palpitations, persistent cramps, dehydration, suspected deficiency, kidney stones, or other unexplained symptoms. Gummy products should be kept away from children, and bulk powders should be avoided by anyone unable to measure them reliably.
Integrity
The topics below focus on what a buyer can verify from the label, directions, quality records, and packaging evidence. Scores distinguish products that disclose and substantiate these details from products that rely mainly on broad claims or incomplete public information.
HHealth & Safety
Likely Net Health Benefit
This measures whether the stated use is plausible at the actual elemental-potassium dose while keeping foreseeable risks low. A high score combines a useful, honestly framed dose with appropriate warnings and a simple formula; the supplied products scoring in the low 70s generally had clearer dosing or more restrained use cases. Lower scores were associated with unclear doses, broad cramp or energy claims, and multi-ingredient uncertainty.
Clear Elemental Potassium Dose
This measures whether the label separates elemental potassium from the weight of its citrate, chloride, gluconate, or bicarbonate compound and gives a realistic serving and daily amount. High-scoring products clearly stated figures such as 99 mg, 300 mg, 365 mg, or 1,020 mg elemental potassium. Low-scoring gummies and liquids used large compound-weight headlines or failed to publish a complete Supplement Facts panel.
Kidney, Heart, and Medication Safety
This measures whether warnings address hyperkalemia—the dangerous buildup of potassium in the blood—and identify kidney, heart, and medication risks. Higher-scoring products at least acknowledged relevant medical use and interactions, while lower-scoring products used only broad medication disclaimers. Across the set, even relatively better scores did not consistently provide prominent warnings naming kidney disease, ACE inhibitors, ARBs, potassium-sparing diuretics, trimethoprim, or urgent symptoms.
Safe Serving Design and Directions
This measures whether the format and directions limit accidental high intake, stomach irritation, and misuse. Capsules and clearly portioned tablets generally scored better because they avoid weighing powder; meal or water directions also helped. Powders and liquids can still be practical when dilution and serving amounts are clear, but unclear scoop sizes, no daily maximum, or contradictory serving math lowered scores.
Complete Formula and Allergen Transparency
This measures whether active nutrients, minerals, sodium, sweeteners, botanicals, excipients, serving sizes, and allergens are fully disclosed. Simple single-ingredient powders and short capsule formulas scored in the mid-to-high 80s. Gummy and liquid products scored lower when magnesium, vitamins, sodium, botanicals, or inactive ingredients were missing or described inconsistently, even when vegan, sugar-free, or allergen-free claims were made.
EEvidence
Independently Certified Quality
This measures current, registry-confirmed certification of the exact finished product for identity, strength, purity, and contaminant control. A high score requires an active listing in a recognized program such as USP Verified or NSF Certified Dietary Supplements; facility or brand claims do not qualify. The supplied products generally scored around 68–78 because exact-product registry confirmation was not established, although one product had independent contaminant certification outside those registries.
Lot-Specific Test Proof
This measures whether a buyer can obtain a current certificate of analysis matched to the bottle’s lot, showing elemental-potassium assay, relevant contaminants, laboratory identity, methods, date, and pass limits. Most products scored around 68–74 because reports were unavailable, generic, or required a lot number. One powder had a historical independent report with potassium, heavy-metal, and microbiological results, but it was not current or matched to present stock.
Contaminant Safety Evidence
This measures documented finished-product control for toxic elements, microorganisms, and other relevant impurities. Higher scores reflected independent contaminant certification or a historical laboratory report; lower scores reflected only manufacturer statements such as “third-party tested” without results, methods, or limits. A clean ingredient list reduces formulation trade-offs but does not itself prove contaminant safety.
Evidence-Matched Claims
This measures whether claims about hydration, cramps, recovery, blood pressure, energy, pH, kidney stones, or heart and bone support match human evidence for the exact formula and elemental dose. Higher-scoring products used narrower nutritional descriptions or disclosed a dose that could be compared with evidence. Lower scores commonly involved treating compound weight as potassium, promoting broad wellness outcomes, or implying cramp relief without product-specific support.
Traceable, Accountable Manufacturer
This measures whether the responsible firm, contact details, lot and expiration information, manufacturing controls, recalls, warning letters, and relevant regulatory history are readily verifiable. The supplied products generally scored in the low-to-mid 70s when a U.S. address or customer contact and basic traceability were available. Scores were limited when accountability depended mainly on unsupported GMP or testing claims, even where no product-specific FDA action was identified.
EEcology
Lower-Waste Packaging
This measures whether packaging minimizes unnecessary material and whether recyclability, recycled content, refill options, or responsible sourcing are documented without compromising moisture protection, tamper evidence, or child safety. Most supplied products clustered around the same middle score because no credible packaging specifications were found. Bulk pouches and tubs may reduce replacement frequency or individual packaging, but the supplied evidence does not establish that they are recyclable or lower-waste.

Nutricost Potassium Citrate 99mg
Buyer Score 98/100Integrity Score 76/100Nutricost
Overview
This is a 500-capsule potassium citrate supplement. The current manufacturer product page states that each capsule provides 99 mg of elemental potassium from potassium citrate, with 500 labeled servings in the larger bottle. That is a small addition to dietary potassium, not a replacement for potassium-rich foods or clinician-directed treatment of low blood potassium. An independent retailer label listing identifies potassium at 99 mg, or 2% Daily Value, and lists rice flour, gelatin capsule, microcrystalline cellulose, vegetable-source magnesium stearate and stearic acid, and silicon dioxide. Nutricost states that the product is non-GMO, gluten-free, made in a GMP-compliant facility, and third-party tested. The facility, rather than this finished product, is listed by NSF to NSF/ANSI 455-2 GMP requirements. No batch-matched certificate of analysis was publicly available for review.
What works
- The elemental-potassium amount and citrate source are plainly stated, 99 mg per capsule.
- The 500-capsule format provides 500 labeled servings without measuring powder or mixing liquids.
- The formula is relatively simple and the retailer label discloses the capsule and processing ingredients.
- Nutricost's manufacturing facility is listed by NSF for NSF/ANSI 455-2 dietary-supplement GMP requirements.
- The manufacturer gives a domestic customer-service phone number and email contact.
What does not
- The 99 mg dose is only 2% Daily Value, so it is unlikely to materially correct a clinically important deficiency without clinician guidance.
- The publicly visible warning is broad and does not specifically name kidney disease, ACE inhibitors, ARBs, potassium-sparing diuretics, or urgent hyperkalemia symptoms.
- The exact finished product is not listed in the USP or NSF dietary-supplement product certification registries reviewed.
- Nutricost claims third-party testing, but it does not provide a current lot-specific, independently issued certificate of analysis to purchasers.
- Marketing that suggests potassium will prevent leg cramps is not supported by the human evidence identified for potassium supplementation.
Who is it for
This product fits a healthy adult who wants a small, clearly quantified potassium addition and prefers capsules over powders, drink mixes, or multi-electrolyte formulas. The large bottle is practical for someone intending to use the labeled one-capsule serving over a long period and who can tolerate gelatin. It is most appropriate when a clinician or dietitian has already reviewed the person's overall potassium intake, kidney function, medical conditions, and medicines. Its 99 mg amount is modest, so expectations should be limited to incremental dietary supplementation.
Who is it not for
It is not appropriate for self-treatment of suspected potassium deficiency, persistent muscle cramps, kidney stones, dehydration, or heart symptoms. People with chronic kidney disease, heart failure, liver disease, adrenal insufficiency, or type 1 diabetes need individualized potassium advice. Those taking an ACE inhibitor, ARB, spironolactone, amiloride, other potassium-sparing diuretics, potassium-containing medicines, or medicines that can raise potassium should ask their prescriber before use. It also does not suit vegans because the listed capsule is gelatin, or people who need a publicly available batch-specific test report.
Integrity
Potassium is essential for nerve signaling, muscle contraction, and normal heart rhythm. In healthy people with normal kidney function, modest supplemental potassium is generally handled by the kidneys. Risk changes substantially when potassium excretion is impaired or medicines reduce potassium loss. NIH identifies kidney disease, ACE inhibitors, ARBs, and potassium-sparing diuretics as important hyperkalemia risks. Severe hyperkalemia can cause weakness, palpitations, paralysis, and dangerous rhythm disturbances. The manufacturer states that the product is non-GMO, gluten-free, and third-party tested. NSF currently lists Nutricost Manufacturing for dietary-supplement GMP facility certification, but that is not an independent certification of this finished product's contents or contaminants. No public lot-matched test report was found. No product-specific FDA recall or warning-letter record was identified in the reviewed searches. The bottle is a long-use plastic package, but the manufacturer provides no verified recycled-content, recyclability, refill, or responsible-sourcing documentation.

Vykee Nutrition Potassium Citrate High Potency
Buyer Score 95/100Integrity Score 66/100Vykee Nutrition
Overview
This is a 120-capsule potassium citrate supplement sold as a 60-serving bottle. Vykee’s own product page states that one serving is two capsules and supplies 500 mg of elemental potassium as citrate, or 10.64% of the Daily Value. That is a meaningful nutritional amount, but it is not a replacement for a potassium-rich diet or a treatment dose for diagnosed low potassium. The product page presents heart, muscle, electrolyte, blood-pressure, energy, and cramp-support claims. Potassium is essential to normal nerve, muscle, fluid, kidney, and heart function, although those broad benefits do not establish that this specific 500 mg serving will relieve cramps or improve energy in a healthy user. The most important product-specific concern is inconsistent dose communication. The marketplace record describes 500 mg per capsule, while the manufacturer describes 500 mg per two-capsule serving.
What works
- The manufacturer identifies elemental potassium, its citrate form, serving size, and Daily Value on its product page.
- A simple formula is reported, potassium citrate in a vegetable capsule, without a multi-electrolyte blend that could add sodium, magnesium, or sweeteners.
- The bottle provides 60 listed servings, which makes the intended two-capsule daily amount easy to calculate.
- The manufacturer provides a U.S. street address, phone number, email contact, and a lot-number lab-report portal.
What does not
- The marketplace description says 500 mg per capsule, but the manufacturer page says 500 mg per two-capsule serving. This is a material dosing inconsistency.
- The manufacturer warning says there are no known adverse interactions or contraindications. That conflicts with established potassium risks for people with kidney impairment and people using medicines that raise potassium.
- The warning text also refers to side effects from magnesium supplements, which appears unrelated to this potassium-only product and weakens confidence in label review.
- No active listing for this exact finished product was found in the checked USP, NSF dietary-supplement, NSF Certified for Sport, or Informed Sport registries.
- The manufacturer describes third-party testing and a lot portal, but a current batch-matched finished-product report showing potassium assay, heavy metals, and microbiological results was not publicly obtainable during review.
Who is it for
This product is most suited to a healthy adult who has discussed potassium intake with a clinician or dietitian, wants a plainly dosed capsule rather than a drink mix, and specifically wants 500 mg elemental potassium per listed daily serving. It can be useful for tracking supplemental potassium alongside dietary intake because the manufacturer gives a serving size and Daily Value. It is better suited to routine nutritional supplementation than to self-treatment of persistent cramps, palpitations, dehydration, kidney stones, or suspected potassium deficiency, which need individualized medical assessment.
Who is it not for
It is not suited to people with chronic kidney disease, reduced potassium excretion, heart failure, adrenal insufficiency, uncontrolled diabetes, or a history of high blood potassium unless a clinician specifically directs its use. People taking ACE inhibitors, ARBs, potassium-sparing diuretics, potassium-containing medicines, or other medicines that affect potassium should seek pharmacist or prescriber advice first. It is also a poor fit for anyone needing a highly verified dose, a publicly available batch-specific certificate of analysis, or independently certified sport-supplement status. Keep it away from children unless a pediatric clinician recommends it.
Integrity
The nutritional strength is that the manufacturer identifies potassium as the nutrient and citrate as the form, instead of presenting only a compound weight. Its stated 500 mg elemental-potassium serving equals 10.64% of the Daily Value. Potassium is physiologically important, but supplemental potassium requires more care than ordinary wellness marketing suggests. People with impaired kidney function or medicines that reduce potassium excretion can develop dangerous hyperkalemia, sometimes without early symptoms. Vykee states that its products are made in GMP-certified facilities, tested by third parties, and supported by a lot-number report portal. Those are manufacturer statements, not independently verified finished-product certifications or publicly reviewed batch reports for this product. Searches did not identify a product-specific FDA recall or warning letter. No credible packaging material, recycled-content, recyclability, refill, or sourcing documentation was found, so the environmental footprint cannot be meaningfully assessed beyond the small plastic supplement bottle format.

Nextdia Potassium & Mineral Gummies 1200mg
Buyer Score 93/100Integrity Score 68/100Nextdia
Overview
This is a grape-flavored gummy supplement sold as two 60-gummy bottles, for 120 gummies total. The marketplace listing identifies potassium citrate and potassium gluconate as the potassium sources, alongside omega-3, magnesium, calcium, turmeric extract, vitamins D3, K2, B6, B12 and E, folate, and zinc. It is marketed for electrolyte balance plus heart, nerve, muscle, bone, brain, circulation, and energy support. The defining limitation is dose clarity. The public listing promotes “1200 mg” of two potassium forms, but it does not provide a clearly stated elemental-potassium amount or public amounts for the other active ingredients. That prevents a reliable comparison with dietary intake or clinical dosing. Potassium is essential for nerve transmission and muscle contraction, but the NIH notes that excess can be dangerous when potassium excretion is impaired or certain medicines are used.
What works
- Chewable gummy format may be practical for adults who cannot comfortably swallow tablets.
- The listed formula uses two potassium salt forms, citrate and gluconate, rather than an unspecified potassium source.
- The responsible distributor publishes a United States address, telephone number, and email contact.
- The public listing includes a broad ingredient roster and identifies the grape flavor and total gummy count.
What does not
- The advertised 1200 mg figure is not clearly identified as elemental potassium or total compound weight, which is a material dosing ambiguity.
- Public product information does not provide quantities for magnesium, calcium, omega-3, turmeric, vitamins, folate, or zinc.
- No current finished-product certification listing was located in USP, NSF, Informed Sport, or Informed Choice registries during this review.
- No batch-matched, independently issued certificate of analysis was publicly available for potency, heavy metals, or microbiological testing.
- The marketplace page does not prominently present kidney-disease, hyperkalemia, or medication-interaction precautions despite potassium-specific risks.
Who is it for
This product is most relevant to a healthy adult who specifically wants a chewable potassium-containing supplement and is willing to verify the bottle label before use. The two-bottle, 120-gummy format may suit someone planning a longer routine rather than a short course. It is better aligned with a person seeking a general dietary supplement than someone trying to self-treat cramps, low blood potassium, kidney stones, high blood pressure, or a diagnosed nutrient deficiency, because the publicly available elemental-potassium dose is unclear.
Who is it not for
It is not appropriate for people with chronic kidney disease, known high blood potassium, heart failure, liver disease, adrenal insufficiency, or type 1 diabetes without clinician guidance. People using ACE inhibitors, ARBs, potassium-sparing diuretics, potassium-containing medicines, or other medicines that affect potassium should ask a clinician or pharmacist first. It also does not fit buyers who need a precisely quantified potassium dose, complete active-ingredient amounts, a lot-specific test report, or an independently certified finished product. Keep gummies away from children, who may mistake them for candy.
Integrity
The brand’s own site identifies Nextdia Nutritional Products as the distributor and supplies a Fountain Valley, California address, phone number, and email. It states that products are made in the United States with global ingredients. This improves basic contact traceability, but it is not the same as independent finished-product certification. No current USP, NSF, Informed Sport, or Informed Choice listing for this finished product was located during the review. No public lot-specific certificate of analysis was found to confirm elemental potassium, heavy metals, or microbiological results for the purchased bottle. The listing makes purity, potency, vegan, and allergen-related claims, but publicly available information does not give a full quantitative Supplement Facts disclosure or a complete excipient and packaging specification. No specific recycled-content, refill, or recyclability documentation was located, so the environmental footprint cannot be meaningfully substantiated beyond the protective plastic gummy packaging.
#4
NatureBell Potassium Magnesium Supplement
Buyer Score 89/100Integrity Score 73/100NatureBell
Overview
This is a 240-capsule potassium and magnesium supplement. The manufacturer’s Supplement Facts image identifies a three-capsule serving with 200 mg elemental potassium as potassium citrate and 200 mg elemental magnesium as magnesium citrate, providing 80 servings. It is a capsule product, not a drink mix, so it does not replace fluid or sodium lost through substantial sweating. The elemental amounts and citrate forms are clearly shown on the manufacturer label image. NatureBell also lists silicon dioxide, magnesium stearate, rice flour, and a gelatin capsule, so it is not vegetarian. The manufacturer says the product is third-party tested and uses a double-sealed, UV-protected amber bottle, but no public batch-matched certificate of analysis, named laboratory report, or recognized finished-product certification listing was located during this review.
What works
- The manufacturer label clearly distinguishes elemental potassium and magnesium from their citrate forms, 200 mg each per three-capsule serving.
- An 80-serving bottle gives a defined, moderate supplemental amount of both minerals for healthy adults who need to supplement dietary intake.
- The complete listed formula includes the capsule and excipients, including gelatin, rice flour, silicon dioxide, and magnesium stearate.
- The product is supplied in a manufacturer-stated double-sealed amber bottle with UV protection.
What does not
- The public product materials reviewed do not show prominent, specific cautions for kidney disease, heart failure, diabetes, liver or adrenal disease, or medicines that can raise potassium.
- No current USP, NSF, Informed Sport, or Informed Choice finished-product certification listing was located for this product.
- NatureBell’s third-party testing statement is not backed by a publicly available, lot-matched certificate of analysis that shows elemental-mineral results, contaminants, methods, laboratory identity, and pass limits.
- The 200 mg potassium dose is only 4% of the Daily Value, and the broad circulation, heart, muscle, and pH claims are not supported by product-specific human trials at this formula and dose.
- Magnesium citrate can cause gastrointestinal effects, and 200 mg supplemental magnesium may be unsuitable for people already using magnesium-containing supplements, laxatives, or antacids.
Who is it for
This product suits a healthy adult who specifically wants a modest, clearly labeled supplemental amount of potassium and magnesium in citrate forms, prefers capsules to flavored powders, and can tolerate a three-capsule serving. It is most relevant as a supplement to food intake, not as treatment for a diagnosed electrolyte abnormality. The 80-serving bottle may also suit someone planning a consistent daily routine who has reviewed their total potassium and magnesium intake with a clinician or pharmacist when medicines are involved.
Who is it not for
It is not appropriate for people with chronic kidney disease, reduced kidney function, heart failure, type 1 diabetes, liver disease, or adrenal insufficiency unless a clinician directs use. Those taking an ACE inhibitor, ARB, spironolactone, amiloride, triamterene, potassium-containing medicines, or other medicines affecting potassium should obtain individualized advice. It is also unsuitable for vegetarians and people avoiding gelatin. Anyone seeking rapid rehydration after heavy sweating should use a product designed to provide fluid and sodium, rather than relying on these capsules.
Integrity
The product’s strongest health transparency point is its Supplement Facts image. It identifies 200 mg elemental potassium as potassium citrate and 200 mg elemental magnesium as magnesium citrate per three-capsule serving. Potassium is essential for normal cell function, and magnesium supports normal physiological functions, but potassium intake can become dangerous when kidney excretion is impaired or when certain medicines reduce potassium loss. Supplemental magnesium can also cause diarrhea, nausea, and abdominal cramping. NatureBell states that the product is third-party lab tested, double sealed, and packed in a UV-protected amber bottle. Those are manufacturer statements, not publicly documented lot-specific proof. No public certificate of analysis or recognized independent certification for this finished product was located. The amber bottle may help protect light-sensitive contents, but the reviewed materials do not document recycled content, bottle resin type, refill options, or local recyclability, so its packaging waste profile cannot be established.

Designs for Health K+2 Potassium Supplement
Buyer Score 86/100Integrity Score 74/100Designs for Health
Overview
This is a 120-capsule potassium supplement for adults. One capsule supplies 300 mg of elemental potassium, listed as potassium bicarbonate and potassium glycinate complex. The disclosed inactive ingredients are a cellulose capsule and vegetable stearate. The manufacturer directs users to take one capsule daily with a meal, or follow clinician direction. The bottle therefore provides up to 120 daily servings. ([supplementfirst.com](https://supplementfirst.com/products/designs-for-health-k-2-potassium?utm_source=openai)) Its main stated use is nutritional support for healthy blood pressure already in the normal range. Human trials and meta-analyses support higher potassium intake as a way to modestly lower blood pressure in some people, especially those with hypertension, low baseline potassium intake, or high sodium intake. However, many trials used substantially larger supplemental amounts than this 300 mg serving, so a clinically meaningful blood-pressure effect from this exact daily dose is not established. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/28024910/?utm_source=openai))
What works
- The elemental potassium amount is clearly stated as 300 mg per capsule, rather than only listing the weights of its potassium compounds. ([supplementfirst.com](https://supplementfirst.com/products/designs-for-health-k-2-potassium?utm_source=openai))
- The formula is simple, with one active nutrient and two disclosed excipients, with no proprietary blend obscuring the potassium dose. ([supplementfirst.com](https://supplementfirst.com/products/designs-for-health-k-2-potassium?utm_source=openai))
- A premeasured one-capsule serving and take-with-meal direction reduce the dosing ambiguity associated with bulk electrolyte powders. ([designsforhealth.com](https://www.designsforhealth.com/api/library-assets/patient-education---k-2-potassium?srsltid=AfmBOorkutQNpDUL34B7p-G7wMbtzTOCpfmjtkuc8TbUDnTGT1pHVCUs&utm_source=openai))
- The stated blood-pressure support claim is cautious rather than a disease-treatment claim, and increased potassium intake has support from human research, although the exact dose remains a limitation. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/28024910/?utm_source=openai))
What does not
- The available product directions provide only general clinician-consultation language. They do not prominently identify kidney disease, heart failure, adrenal insufficiency, or high-potassium symptoms as specific safety concerns. ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Potassium-HealthProfessional/?trk=public_post_reshare-text&utm_source=openai))
- The label does not specifically flag important medication categories, including ACE inhibitors, ARBs, and potassium-sparing diuretics, which can raise potassium to unsafe levels when combined with supplementation. ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Potassium-HealthProfessional/?trk=public_post_reshare-text&utm_source=openai))
- No current exact-product listing was found in the USP Verified or NSF dietary-supplement certification registries. A Designs for Health vitamin product appears in NSF listings, but that does not verify this potassium product. ([info.nsf.org](https://info.nsf.org/Certified/Dietary/Listings.asp?ProductType=Vitamin&StandardExt=FP&utm_source=openai))
- No buyer-accessible, lot-matched independent certificate of analysis for this product was located. Brand-level discussion of testing is not batch-specific proof of this product's potency or contaminant results. ([podcast.designsforhealth.com](https://podcast.designsforhealth.com/podcasts/season-4-episode-7-quality-control-in-the-supplement-industry-with-elan-m-sudberg/?utm_source=openai))
Who is it for
This product fits an adult who has been advised by a clinician to increase potassium modestly and wants a simple capsule rather than a flavored electrolyte blend or powder. Its 300 mg serving is clearly labeled and its 120-capsule format can suit a roughly four-month once-daily routine. It is most sensible when potassium intake, kidney function, and medicines have already been reviewed, particularly because the claimed blood-pressure role is nutritional support rather than a substitute for evaluating or treating hypertension. ([supplementfirst.com](https://supplementfirst.com/products/designs-for-health-k-2-potassium?utm_source=openai))
Who is it not for
It is not appropriate for self-treatment of high blood pressure, muscle cramps, fatigue, or suspected low potassium without clinical assessment. People with chronic kidney disease, heart failure, liver disease, type 1 diabetes, or adrenal insufficiency need individualized advice because they may develop hyperkalemia at ordinary potassium intakes. People using ACE inhibitors, ARBs, spironolactone, amiloride, or other potassium-retaining medicines should have a pharmacist or prescriber review the full regimen before use. Pregnant or breastfeeding users should also seek clinician guidance. ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Potassium-HealthProfessional/?trk=public_post_reshare-text&utm_source=openai))
Integrity
The health-positive feature is label clarity. Independent label-database material and manufacturer documentation agree that one capsule provides 300 mg elemental potassium from potassium bicarbonate and potassium glycinate complex, with a short disclosed excipient list. The take-with-meal direction is sensible for a capsule, but the available label information does not give specific, prominent safeguards for kidney impairment or potassium-retaining medicines. Those omissions matter because dangerous hyperkalemia can occur in susceptible people. ([supplementfirst.com](https://supplementfirst.com/products/designs-for-health-k-2-potassium?utm_source=openai)) No current exact-product USP, NSF dietary-supplement, Certified for Sport, or Informed certification listing was located. No public lot-specific certificate of analysis was found for this product. Searches also did not identify an FDA recall or warning letter specific to this product, but that is not independent proof of finished-product purity. The product is sold in a conventional capsule bottle, and no credible recycled-content, recyclability, refill, or lower-waste packaging documentation was located.

This two-bottle pack supplies 120 strawberry gummies, with two gummies as a serving and 60 total servings. The manufacturer-displayed Supplement Facts state 200 mg elemental potassium as potassium citrate, 60 mg elemental magnesium from 500 mg magnesium glycinate, 50 mg calcium carbonate, 10 mg zinc, 100 mg vitamin C, vitamins D3, K2, and B6, 100 mg chia-derived omega-3, and 10 mg black pepper. It also lists xylitol and erythritol, zero added sugar, and 15 calories per serving. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600)) The key qualification is label consistency. Current marketing calls out 200 mg potassium citrate and describes whole-food calcium, while the displayed facts panel identifies 200 mg potassium and calcium carbonate. Sleep, cramp, mood, muscle, immune, and bone claims are broad, and no human study of this exact formula or lot-matched independent report was located. The serving is modest rather than a high-potassium dose, but potassium still warrants medication and kidney safety screening. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
What works
- The displayed facts panel separates 200 mg elemental potassium from potassium citrate and identifies magnesium as 60 mg elemental magnesium from 500 mg magnesium glycinate. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600))
- A two-gummy serving is clearly portioned and provides 15 calories with zero added sugar, according to the manufacturer-displayed facts panel. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600))
- The visible formula discloses the secondary nutrients and other ingredients, including calcium, zinc, chia-derived omega-3, black pepper, xylitol, erythritol, pectin, and acids. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600))
- The manufacturer publishes a customer-support phone number and email contact. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
What does not
- The product's own marketing and facts panel conflict on whether 200 mg refers to potassium citrate or elemental potassium, and on whether the calcium is whole-food calcium or calcium carbonate. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
- The manufacturer calls the product third-party lab certified, but no active USP, NSF, Informed Sport, or Informed Choice finished-product certification was identified in the relevant public registries. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
- No current, lot-matched certificate of analysis showing elemental-potassium assay, heavy metals, or microbiological results was made available in the reviewed product materials. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
- The reviewed product page and displayed label do not provide specific kidney-disease, hyperkalemia, ACE inhibitor, ARB, potassium-sparing diuretic, or trimethoprim precautions. These risks can apply even below usual dietary potassium targets in susceptible people. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600))
- Claims for leg cramps, sleep, mood, immunity, muscle relaxation, heart support, and bone support are wider than the evidence shown for this exact low-dose, multi-ingredient gummy. ([lukaree.com](https://lukaree.com/products/potassium-magnesium-gummies-60-count))
Who is it for
This product suits a healthy adult who specifically wants a chewable, modest-dose mineral and vitamin add-on rather than a high-dose potassium product. The facts panel gives 200 mg elemental potassium and 60 mg elemental magnesium per two gummies, with no added sugar and a disclosed sweetener system based on xylitol and erythritol. It is most relevant to someone whose clinician or pharmacist has already confirmed that supplemental potassium fits their diet, medicines, and kidney function. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600))
Who is it not for
It is not suited to people with chronic kidney disease, known high blood potassium, heart-rhythm problems, or an unexplained history of weakness or palpitations without clinician guidance. People using ACE inhibitors, ARBs, potassium-sparing diuretics, potassium-containing medicines, or trimethoprim should seek individualized advice before adding potassium. It is also a poor fit for buyers who need a registry-confirmed certification or a batch-specific independent test report, and for households seeking a supplement specifically evaluated for children. ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Potassium-HealthProfessional/?trk=public_post_reshare-text&utm_source=openai))
Integrity
The disclosed formula provides 200 mg potassium and 60 mg elemental magnesium per serving, not 500 mg elemental magnesium. Magnesium from supplements can cause diarrhea, nausea, and abdominal cramping at higher intakes, while impaired potassium excretion or certain medicines can raise the risk of hyperkalemia. The visible label does not show targeted warnings for those higher-risk groups. ([lukaree.com](https://lukaree.com/cdn/shop/files/1_b54f1ee9-b1e1-4581-bb01-ca8ace8e11fc.png?v=1766397804&width=1600)) Lukaree markets this product as third-party lab certified and uses GMP-related language, but an active finished-product certification was not identified in the reviewed independent certification registries, and no lot-specific certificate of analysis was provided. No product-specific public FDA recall or warning letter was identified in the sources reviewed. The reviewed materials do not provide recycled-content, recyclability, refill, or responsible-sourcing documentation, so its packaging footprint cannot be substantiated beyond the need for a moisture-protective gummy container.

NEVISS Potassium Citrate Gummies 1000mg
Buyer Score 83/100Integrity Score 72/100NEVISS
Overview
This is a raspberry-flavored, sugar-free gummy electrolyte supplement sold as two 60-gummy bottles. The available product label directs adults to take two gummies with a meal, giving 30 servings per bottle. That serving is labeled as 1,000 mg of elemental potassium, supplied as potassium citrate, not merely 1,000 mg of the citrate compound. The same label lists 150 mg magnesium from citrate and glycinate, 200 mg calcium, 50 mg sodium, 5 mg zinc, vitamin B6, vitamin B12, and 10 mg black pepper extract. The ingredient and allergen information is unusually specific for a gummy. The marketed leg-cramp, energy, and performance uses are less well established. Potassium has essential physiologic roles, but human evidence does not support potassium as a general treatment for ordinary leg cramps. No current exact-product USP, NSF, Informed Sport, or Informed Choice certification, or batch-matched independent certificate of analysis, was verified.
What works
- The available Supplement Facts panel clearly distinguishes 1,000 mg potassium as elemental potassium supplied as potassium citrate.
- Two-gummy servings and instructions to take the product with a meal are plainly stated on the available label.
- The label fully quantifies the listed vitamins, minerals, sodium, black pepper extract, and other ingredients.
- The available label states zero added sugar and lists no dairy, gelatin, soy, eggs, wheat, peanuts, shellfish, or artificial colors or flavors.
What does not
- Leg-cramp relief, energy, and body-performance marketing exceeds the human evidence available for potassium in typical leg cramps.
- A 1,000 mg potassium serving is substantial for people with impaired potassium excretion, yet the available label image does not show prominent, specific medicine and kidney-risk instructions.
- No exact-product independent certification was verified in the major certification registries checked.
- No current lot-matched independent certificate of analysis was located to confirm potassium potency, heavy metals, or microbiological results for a bottle in hand.
- The black pepper extract adds an additional interaction consideration, while the product does not provide publicly verified batch testing or a detailed safety rationale.
Who is it for
This product is most suited to a healthy adult who specifically wants a high, clearly stated potassium serving in a chewable format and can review total potassium intake from food, salt substitutes, medicines, and other supplements. It may fit someone who dislikes tablets and prefers a sugar-free gummy with magnesium, calcium, and modest sodium included. It is not a substitute for evaluating persistent cramps, recurrent dehydration, or suspected electrolyte deficiency with a clinician, especially because the cramp claim is not well supported for typical adult leg cramps.
Who is it not for
It is not suited to people with chronic kidney disease, reduced kidney function, heart failure, adrenal insufficiency, type 1 diabetes, liver disease, existing high blood potassium, or unexplained palpitations or muscle weakness unless a clinician has directed use. People taking ACE inhibitors, ARBs, potassium-sparing diuretics, potassium-containing medicines, regular NSAIDs, or trimethoprim-containing medicines should seek clinician or pharmacist guidance first. It is also not a good fit for children, for people needing treatment of a diagnosed potassium disorder, or for households wanting independently certified and lot-tested supplement quality evidence.
Integrity
The available product label is transparent about the active formula. Per two gummies, it lists 1,000 mg potassium as potassium citrate, 150 mg magnesium, 200 mg calcium, 50 mg sodium, 5 mg zinc, vitamins B6 and B12, and 10 mg black pepper extract. It also identifies pectin, monk fruit extract, stevia, coconut oil, sodium citrate, and natural raspberry flavor. The label states zero added sugar and excludes several common dietary ingredients, including dairy and gelatin. A retailer repeats the manufacturer's statements that the gummies are made in a cGMP-certified U.S. facility and third-party tested, but no exact-product certification listing, independent laboratory report, or batch-matched certificate of analysis was verified. Searches did not identify a product-specific FDA recall or warning letter, which is not proof of finished-product quality. The product is supplied in small plastic gummy bottles, and no recycled-content, recyclability, refill, or other packaging-impact documentation was found.

Univera KM Liquid Mineral Supplement
Buyer Score 80/100Integrity Score 65/100Univera
Overview
KM is a 32 fluid ounce liquid mineral and botanical supplement. The manufacturer describes it as a roughly one-month supply and directs adults to shake it, then use a 15 mL serving directly or mixed with water. Its current directions are ambiguous, saying 15 mL daily while also referring to morning and evening use. The manufacturer lists potassium citrate and glycerophosphate, calcium, iron, iodine, 13 named botanicals, caramel color containing sulfites, glycerin, flavoring, and methylparaben and propylparaben. It does not publish a current elemental-potassium amount or botanical quantities on the product page. A Canadian KM licence record lists 2.4 mg potassium, but is marked not marketed and cannot confirm the composition of this U.S. product. The formula's strongest claims involve pH balance, blood oxygenation, detoxification, energy, digestion, and cramp comfort, none supported by product-specific human trials located in this review.
What works
- Liquid directions allow dilution with water, which may make the earthy, bitter flavor easier to tolerate.
- The manufacturer names mineral forms, 13 botanicals, preservatives, caramel color containing sulfites, and flavoring rather than using a single undisclosed blend name.
- The product page provides a U.S. customer-service phone number and email contact.
- The manufacturer states that finished product testing includes heavy metals, although it does not provide a batch-matched report.
What does not
- The currently published information does not state a usable elemental-potassium amount per serving or per day, so it cannot be compared reliably with dietary intake or a clinician's recommendation.
- The directions conflict between a daily 15 mL serving and morning-and-evening use, which creates avoidable dosing uncertainty.
- Claims about changing body pH, oxygenating blood, eliminating toxins, and predictable results within days are not matched to disclosed doses or product-specific human evidence.
- No current USP, NSF, Informed Sport, or Informed Choice certification listing, or public lot-specific certificate of analysis, was located for this finished product.
- Licorice is part of the formula. Its glycyrrhizin content is not disclosed, despite known concerns for blood pressure, heart rhythm, and potassium balance in susceptible people.
Who is it for
This product is most suited to an informed adult who wants a bitter liquid botanical-mineral tonic, accepts a 15 mL routine that may be mixed with water, and is not relying on it to correct a medically confirmed potassium deficiency. The user should have normal kidney function, no relevant medication interactions, and a clinician who can review the complete formula if regular use is planned. It is more practical for someone comfortable with a one-month bottle than for someone needing precise nutrient dosing.
Who is it not for
It is not suited to people with chronic kidney disease, heart failure, liver disease, adrenal insufficiency, diabetes with potassium concerns, or a history of high potassium. People taking ACE inhibitors, ARBs, potassium-sparing diuretics, potassium-containing medicines, trimethoprim, or medications affected by herbs should use clinician guidance instead. Pregnant or nursing people, children, people with hypertension or heart-rhythm concerns, and anyone seeking measured potassium replacement should choose a product or treatment with clear dosing and tailored medical oversight.
Integrity
The public ingredient list identifies potassium citrate and glycerophosphate, calcium, iron, iodine, chamomile, sarsaparilla, dandelion, horehound, licorice, seneca snakeroot, passionflower, thyme, gentian, saw palmetto, alfalfa, dong quai, and celery. It also lists caramel color containing sulfites, natural flavors, glycerin, methylparaben, and propylparaben. This conflicts with the manufacturer's broader statement that the formula contains nothing artificial. The manufacturer says KM is tested for heavy metals, but no independently issued, lot-matched certificate was available to verify assay or contaminant limits. Searches of public USP, NSF, Informed Sport, and Informed Choice registries did not identify a current certification for this finished product. Searches of FDA public recall and warning-letter resources did not identify a KM-specific action. No recycled-content, recyclability, refill, or responsible-sourcing documentation was found for the plastic bottle, so its packaging footprint remains unverified.

NEVISS Potassium Gluconate Gummies with Magnesium & B6
Buyer Score 79/100Integrity Score 71/100NEVISS
Overview
This is a 60-count strawberry gummy supplement with 30 two-gummy servings. The independently photographed Supplement Facts panel lists 1,300 mg potassium gluconate, providing 100 mg elemental potassium, plus 200 mg magnesium as magnesium glycinate, 2 mg vitamin B6 as pyridoxal-5-phosphate, and 100 mg L-theanine per serving. The ingredient amounts and the distinction between potassium gluconate and elemental potassium are unusually clear. The potassium amount is only 2% of the Daily Value, while magnesium supplies 48%. That makes it a modest potassium add-on rather than a replacement for dietary potassium or clinician-directed treatment of low potassium. The product presents hydration, leg-cramp, heart-rhythm, energy, calm, and sleep-related claims, but no finished-product independent certification, batch-matched certificate of analysis, or product-specific clinical evidence was located. The visible label also does not present kidney-disease, medication-interaction, or hyperkalemia guidance.
What works
- The Supplement Facts panel clearly identifies 100 mg elemental potassium from 1,300 mg potassium gluconate per two-gummy serving.
- It supplies 200 mg magnesium as magnesium glycinate, or 48% of the Daily Value, alongside modest vitamin B6 and L-theanine amounts.
- The photographed label lists zero total sugar and states that it is vegan, gelatin-free, gluten-free, and free of several listed allergens and artificial colors or flavors.
- A two-gummy serving is portioned rather than a bulk powder, which limits accidental large scoops.
What does not
- The prominent 1,300 mg figure is potassium gluconate weight, not elemental potassium. The actual elemental potassium amount is 100 mg per serving.
- Hydration, cramp, heart-rhythm, energy, calm, and sleep claims are broader than the product-specific human evidence located for this exact formula and dose.
- No active listing was located in USP or NSF finished-product certification registries, and no lot-matched independent certificate of analysis was available to review.
- The visible label does not show specific warnings for chronic kidney disease, heart failure, diabetes, adrenal disease, liver disease, ACE inhibitors, ARBs, potassium-sparing diuretics, or other medicines that can raise potassium.
Who is it for
This product suits a healthy adult who specifically wants a low elemental-potassium gummy rather than a high-dose potassium medicine, and who also values a meaningful magnesium contribution. Its 30-serving bottle and two-gummy format may suit someone who dislikes tablets and wants to track intake from a fully itemized label. It is most appropriate as a modest dietary supplement, not as self-treatment for confirmed low potassium, recurrent cramps, dehydration, palpitations, or a heart-rhythm concern.
Who is it not for
It is not appropriate for people with chronic kidney disease, heart failure, type 1 diabetes, liver disease, adrenal insufficiency, or known high potassium unless a clinician advises the total potassium intake. Avoid self-selecting it while taking an ACE inhibitor, ARB, potassium-sparing diuretic, potassium-containing medicine, or other medicine that can increase potassium. It also does not fit buyers seeking clinician-directed correction of hypokalemia, since 100 mg elemental potassium per serving is small and recurrent cramps or palpitations need medical assessment.
Integrity
Potassium is essential for nerve, muscle, kidney, and heart function. In healthy people with normal kidney function, kidneys usually regulate excess intake. Risk changes substantially with impaired potassium excretion or medicines that retain potassium. NIH notes that ACE inhibitors, ARBs, and potassium-sparing diuretics can raise potassium, and severe hyperkalemia can cause weakness, palpitations, paralysis, and dangerous arrhythmias. The visible product label does not provide these targeted safeguards. The formula is transparent about its active ingredients, has zero listed sugar, and states vegan and gelatin-free status. Those are label claims, not independent certification. Searches did not locate a product-specific USP or NSF certification listing, a lot-matched independent certificate of analysis, or documented recycled-content, recyclability, refill, or sourcing evidence. The packaging appears to be a conventional single-use gummy bottle, so its environmental attributes cannot be confirmed.

Nutricost Potassium Chloride Powder 1kg
Buyer Score 76/100Integrity Score 74/100Nutricost
Overview
This is a 1 kg tub of unflavored potassium chloride powder. Nutricost states that one 1/8 teaspoon, 0.7 g serving, provides 365 mg elemental potassium from potassium chloride. The stated directions are to mix one serving daily with 6 to 10 ounces of water, or use as directed by a health professional. A container is stated to hold about 1,425 servings. The clearly stated elemental-potassium amount is useful for tracking intake, but this is still a concentrated bulk powder. Its 365 mg serving is a modest contribution to daily potassium intake, not a substitute for clinical evaluation or monitored treatment of low blood potassium. Nutricost states that the product is third-party tested and made in a GMP-compliant facility. The manufacturing facility is listed by NSF to its GMP facility standard, but no current public certification for this exact finished product or batch-matched certificate of analysis was found.
What works
- The stated 0.7 g serving clearly identifies 365 mg elemental potassium from potassium chloride.
- Single-ingredient, unflavored format avoids added sweeteners and multi-electrolyte trade-offs, according to the manufacturer.
- Nutricost states the product is soy-free, gluten-free, and non-GMO.
- Nutricost Manufacturing is listed by NSF as meeting NSF/ANSI 455-2 GMP requirements for dietary-supplement manufacturing facilities.
What does not
- The label information located gives only a broad medication consultation warning, rather than prominent, specific warnings for kidney disease, heart failure, hyperkalemia, ACE inhibitors, ARBs, potassium-sparing diuretics, or NSAIDs.
- A bulk powder can be mismeasured or added repeatedly. The located directions do not state a maximum daily amount, use with food, or urgent symptoms of high potassium.
- No public, lot-matched certificate of analysis was located to confirm this purchaser's potassium assay, heavy-metal results, microbiology, laboratory, methods, and limits.
- The NSF listing covers the manufacturing facility's GMP system. It is not an NSF finished-product certification for this potassium powder.
- No packaging recycled-content, recyclability, refill, or material documentation was located.
Who is it for
This product fits a healthy adult who has been advised to increase potassium intake, understands their total intake from foods, salt substitutes, drinks, and supplements, and wants a plain potassium chloride powder rather than capsules or flavored electrolyte mixes. The small stated serving, 365 mg potassium, can be measured into a beverage for a routine that has already been discussed with a clinician or dietitian. The 1 kg size is most practical for regular, careful home use rather than occasional supplementation.
Who is it not for
It is not appropriate for people with chronic kidney disease, known high potassium, heart failure, type 1 diabetes, liver disease, adrenal insufficiency, or a history of potassium-related heart rhythm problems unless their clinician has specified a dose and monitoring plan. People taking ACE inhibitors, ARBs, spironolactone, amiloride, eplerenone, aliskiren, or regular NSAIDs should not self-dose potassium. It is also a poor fit for households where children could access a bulk powder, or for anyone needing clinician-managed treatment of confirmed hypokalemia.
Integrity
Potassium is an essential nutrient, and the stated serving provides 365 mg elemental potassium. In people with normal kidney function, potassium from foods is generally handled by kidney excretion. Risk changes substantially with impaired potassium excretion or interacting medicines. NIH notes that kidney disease and medicines including ACE inhibitors, ARBs, and potassium-sparing diuretics can raise the risk of dangerous hyperkalemia. Prescription potassium chloride labeling also directs dilution and administration with meals to reduce gastrointestinal irritation. Nutricost states that this product is independently tested by ISO-accredited laboratories, but a buyer-accessible, lot-specific report was not located. NSF currently lists Nutricost Manufacturing for GMP facility certification, which supports process controls but does not verify the identity, potency, or contaminants of this finished tub. No product-specific recyclable-content, refill, or recycling documentation was found, so its 1 kg plastic container has no verified lower-waste packaging advantage.
