Overview

365 by Whole Foods Market's Sustained Release Potassium tablets deliver 99mg of potassium per tablet across a 250 count bottle, formulated as vegan and labeled certified.

99mg per tablet is the standard dose regulators allow for over the counter potassium supplements in the US, well below what a prescription potassium supplement would provide, so this fits a maintenance role rather than a diagnosed deficiency. The sustained release format is meant to spread absorption over time instead of a single spike.

  • 99mg potassium per tablet
  • 250 tablets per bottle
  • Sustained release formula
  • Vegan

Who it's for

Works for someone looking for a basic, vegan, sustained release potassium tablet at the standard over the counter dose. Not suited to anyone whose doctor has prescribed a therapeutic potassium dose, since 99mg tablets are capped well below that level.

Pros and cons

Pros
  • Vegan tablet formula
  • Sustained release format
  • Large 250 count bottle
Cons
  • 99mg dose is capped at the standard OTC limit, not a therapeutic dose
  • Unflavored, no added nutrients

Performance notes

Sustained release tablets are designed to break down gradually rather than all at once, spreading the 99mg potassium dose over a longer window after swallowing. That dose reflects the FDA cap on over the counter potassium supplements, a limit set due to potassium's narrow safety margin at higher doses.
