Overview
A potassium citrate capsule from Pure Encapsulations, 90 capsules per bottle, unflavored and gluten free, positioned to support nerve and muscle function, adrenal and hormone activity, heart health and energy.
Potassium citrate is the electrolyte form used here rather than a food-based potassium source, and capsule potassium supplements are generally kept to conservative per-serving amounts for safety, since this data doesn't state the exact milligrams per capsule, anyone dosing precisely should confirm that on the physical label. The unflavored, gluten-free formulation keeps the product simple rather than layering in extra ingredients.
- Potassium citrate electrolyte support
- Gluten free formula
- 90 capsule count
- Targets nerve, muscle and heart health
Who it's for
People who want a straightforward potassium citrate capsule without flavoring, particularly anyone tracking electrolyte intake alongside diet. Not a fit for someone who needs a high, prescription-level potassium dose from a single capsule.

Performance notes
