Potassium is a vital mineral serving as a core intracellular electrolyte linked to muscle and nerve function, and supporting heart health. This formula uses potassium citrate, a highly absorbable form, which is often picked for its friendly bioavailability in vegan capsules.

Potassium helps keep fluid balance stable, supports normal muscle contraction and nerve signalling, and helps offset sodium's impact on blood pressure. Dr. Sakhaee from the University of Texas showed that potassium citrate therapy raises urinary potassium with a favourable safety profile in adults, backing its part in cardiovascular health through steady blood pressure and muscle function.
