Overview

A vegetarian caplet delivering 99mg of potassium gluconate per dose, the standard OTC potassium level in the US. The 250-count bottle is sized for once-daily use across roughly 250 days.

This sits at the conventional low-dose end of the potassium category rather than a higher-potency softgel or gummy format. Vitamin World frames it around electrolyte, muscle, nerve, and heart support, and the once-daily, gluten-free format keeps the routine simple.

  • 99mg potassium gluconate per caplet
  • 250 caplets, about 250 days of use
  • Vegetarian formula
  • Gluten-free

Who it's for

Adults wanting a straightforward, standard-dose potassium caplet for daily maintenance rather than a higher-potency product fit this one well. It's less suited to anyone seeking a chewable or softgel format, or a higher milligram dose.

Pros and cons

Pros
  • Vegetarian and gluten-free caplet
  • Long 250-day supply per bottle
  • Standard once-daily dosing
Cons
  • 99mg is a maintenance dose, not high-potency
  • Caplet form only, no flavor masking

Performance notes

At 99mg per caplet, this sits at the conventional OTC potassium ceiling used across the US supplement market, a level set well below food-based potassium intake for safety reasons rather than a strength limitation specific to this brand. Once-daily dosing across a 250-count bottle gives around eight months of use before a refill.
