Analysis

Citrate, aspartate, and gluconate provide three soluble potassium sources in one capsule. The listed amount is modest, so it adds only a small share of typical daily potassium needs.

Its focused design supports fluid balance and normal electrical signaling without unrelated ingredients. No magnesium or other nutrients broaden the formula beyond basic potassium support.

The long supply is practical for people who deliberately want a low amount. People with kidney impairment or medicines that retain potassium should still count it toward total supplemental intake.

Who is it for
  • Adults seeking a small potassium top-up
  • People who prefer capsules with organic mineral forms
Best for
  • Low-dose daily potassium support
  • Sodium-potassium balance

Pros

  • Three disclosed organic potassium forms
  • Simple single-mineral formula
  • Long container supply

Cons

  • Only a modest contribution to daily potassium needs
  • No complementary magnesium
  • Narrow cardiovascular pathway coverage

Warnings

  • The 99 mg potassium serving may be unsuitable with impaired kidney function because potassium can accumulate.
  • ACE inhibitors, ARBs, and potassium-sparing diuretics can increase the risk of excessive blood potassium.
  • Taking potassium without enough fluid or food may cause stomach irritation in sensitive users.

Nutrient quality

78 High impact

Citrate, aspartate, and gluconate are useful organic potassium forms. The elemental serving amount is too small to contribute much toward daily potassium needs, while the low amount avoids obvious overdosing in healthy adults.

Ingredient transparency

71 High impact

The three source lines repeat the same potassium amount, leaving the combined elemental total less intuitive. Serving totals are apparent, but full directions and inactive ingredients are not supplied.

Customer satisfaction

66 High impact

The supplied average rating is exceptionally strong. The moderate rating base offers some confidence but is not extensive, while complaint and firsthand experience details are unavailable.

Value for money

89 Highest impact

Formula quality provides partial support for the asking position. The serving value is highly competitive within the category.

B- Goal FitD+ Strength of SupportD- CoverageA Formula Quality

Potassium citrate, aspartate, and gluconate provide usable forms for sodium-potassium balance. The capsule is simple and clearly focused.

The amount is only a small fraction of daily potassium needs and is unlikely to materially affect vascular support alone. No complementary magnesium or other cardiovascular active is included.

Report overview
A+ Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyD+ Value

Citrate and aspartate provide well-absorbed organic potassium forms, with gluconate adding another usable source. The 99 mg serving remains modest for general potassium support. A very low serving cost partly offsets the limited dose.
