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.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vegan tablet formula
- Sustained release format
- Large 250 count bottle
- 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.
