What is the recommended dosage for Potassium?

Supplements: Typically 99 mg/dose (FDA limit per unit); Dash Diet Target: 4,700 mg/day; Who Recommendation: 3,510 mg/day from food

What are the side effects of Potassium?

Potential side effects include: Gastrointestinal irritation (nausea, vomiting, diarrhea), Hyperkalemia risk in patients with renal impairment, Cardiac arrhythmias at excessively high serum levels.

What is potassium and how may it support cardiovascular health?

Potassium is an essential mineral critical for heart rhythm, muscle contraction, and blood pressure regulation. Higher potassium intake is consistently associated with lower blood pressure and reduced stroke risk. The DASH diet, which is high in potassium, is a cornerstone of hypertension management.

What is the recommended intake of potassium for cardiovascular health?

The Adequate Intake for potassium is 2,600 mg/day for women and 3,400 mg/day for men. Most Americans consume only about 2,500 mg daily. Supplemental potassium is limited to 99 mg per pill in the US due to safety concerns. Food sources (bananas, potatoes, beans) are preferred over supplements.

What are the potential side effects of potassium supplements?

Hyperkalemia (excess potassium) can cause life-threatening cardiac arrhythmias. Potassium supplements are particularly dangerous for individuals with kidney disease, those taking ACE inhibitors, ARBs, or potassium-sparing diuretics. Nausea and diarrhea may occur. Potassium supplementation should be medically supervised.

About

Potassium is the primary intracellular cation essential for maintaining cell membrane potential and cardiac rhythm. It promotes sodium excretion, directly counteracting sodium's hypertensive effect. A 2013 Cochrane-grade meta-analysis found increased potassium intake reduced systolic blood pressure by 3.49 mmHg in hypertensive adults. The DASH diet (4,700 mg K/day) reduces systolic BP by 8-14 mmHg.

How It Works

Primary intracellular cation essential for cardiac rhythm; promotes sodium excretion by inhibiting renal sodium reabsorption, directly counteracting sodium's hypertensive effect; relaxes vascular smooth muscle via Na+/K+-ATPase activation; suppresses reactive oxygen species in vascular endothelium.
