What it is
Potassium citrate supplies potassium and citrate; citrate participates in acid-base balance and changes urinary citrate.
Core function and why it is studied
The core connection is the recognized physiological role described above. Research therefore examines electrolyte and urinary-mineral measures, while supplement value still depends on baseline intake or status, the form used, and the outcome being measured.
What the evidence means
The physiological role is well established. Supplement benefit is most predictable when intake or status is inadequate; more is not automatically better.
How to compare products
Compare the exact nutrient form, amount per serving, Daily Value where applicable, elemental amount for minerals, and total intake from other products.
