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.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vegetarian and gluten free formula
- Simple one caplet per day
- 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.
