What it is

A non-chloride potassium salt useful when additional potassium is needed without the GI irritation and metabolic acid-base effects of potassium chloride. US supplements are limited to 99 mg elemental potassium per tablet (FDA), which is a small fraction of the ~3500-4500 mg daily requirement — most dietary potassium must come from food. Useful for gentle top-up in high-sweat situations, low-potassium diets (eg carnivore), and alongside thiazide diuretics under supervision.
