Overview

Low-dose potassium gluconate caplet from Nature's Bounty, providing 99 mg per caplet, the regulated over-the-counter ceiling, in a vegetarian, gluten free, 100-count bottle meant to round out dietary potassium intake.

US regulations cap over-the-counter potassium supplements at 99 mg per dose because larger single doses of potassium salts can affect the gut or heart rhythm, so this reflects the standard ceiling rather than a therapeutic amount. It's meant to complement diet, not replace a potassium-rich eating pattern.

  • 99 mg potassium gluconate per caplet
  • Vegetarian and gluten free
  • One caplet per day
  • 100-count bottle

Who it's for

People wanting a modest, regulation-capped daily potassium supplement to round out their diet. Not for anyone with a diagnosed potassium deficiency, since 99 mg is far below the doses used for medical replacement.

Pros and cons

Pros
  • Vegetarian and gluten free formula
  • Simple one caplet per day
Cons
  • 99 mg will not correct a deficiency
  • Just over three months' supply

Performance notes

At 99 mg, the dose sits at the FDA's over-the-counter ceiling for potassium supplements, a limit set because larger single doses can irritate the gut or affect heart rhythm. The caplet uses potassium gluconate and is vegetarian and gluten free.
