Overview
Thorne's Potassium Citrate is a third-party certified electrolyte capsule aimed at muscle function, heart health, nerve function and urinary tract support, sold in a 90-capsule, unflavored, gluten free bottle.
Potassium citrate is the specific salt form used here rather than potassium chloride, and citrate forms are typically the ones associated with urinary tract and kidney-related use. Thorne markets the product as third-party certified, which speaks to manufacturing verification rather than any effect on outcomes.
- Potassium citrate electrolyte formula

Who it's for
Suits someone whose electrolyte or urinary tract support routine calls specifically for potassium citrate rather than a generic multi-mineral blend. Not intended as a substitute for medical treatment of kidney stones or heart rhythm issues, both areas where potassium levels need clinician oversight.
Pros and cons

Performance notes
Citrate is the counter-ion Thorne uses here instead of chloride, a form more commonly tied to urinary tract and kidney-related supplementation, and the capsule is unflavored with a 90-count bottle for daily use.
