What is Potassium Citrate?
Potassium is a major intracellular electrolyte essential for nerve signaling, muscle contraction (including the heart), and blood pressure regulation. The 4,700 mg/day recommended intake is met by fewer than 5% of US adults. Inadequate potassium relative to sodium contributes meaningfully to hypertension. Supplementing potassium to balance dietary sodium consistently lowers blood pressure in trials. By US law, single-supplement potassium doses are capped at 99 mg to prevent acute hyperkalemia, but multiple servings per day are safe for most. Avoid with kidney disease or potassium-sparing medications.
Most adults eat too little potassium. Adequate intake lowers blood pressure and counteracts excess sodium.
