Potassium

MODERATE EVIDENCEMineralLast updated

AVELOR SUMMARY

Potassium is the most under-consumed essential mineral in Western diets — 98% of Americans fail to meet the adequate intake of 4,700mg/day. Our research shows robust evidence for blood pressure reduction: a meta-analysis of 33 RCTs found potassium supplementation reduced blood pressure by 3.5/2.0 mmHg, with greater effects (nearly 6 mmHg systolic) in hypertensives with high sodium intake. The critical safety concern: potassium supplements are FDA-limited to 99mg per unit dose due to hyperkalemia risk, which can cause fatal cardiac arrhythmias — especially in patients with kidney disease or on potassium-sparing medications.

WHAT IT DOES

Potassium is the primary intracellular cation — 98% of body potassium is inside cells, creating the electrical gradient essential for nerve impulses, muscle contractions, and cardiac rhythm. For blood pressure, potassium works through: (1) increasing renal sodium excretion (natriuresis) — directly countering sodium's hypertensive effect; (2) vasodilation via endothelial nitric oxide; (3) reducing sympathetic nervous system activity. The sodium:potassium ratio in the diet is now considered more important than absolute sodium intake — high potassium blunts the BP-raising effect of sodium.

OPTIMAL DOSAGE

Look for: Potassium citrate or potassium chloride; 99mg per capsule (FDA max); third-party tested
Avoid: Large-dose potassium tablets (GI ulceration); sustained-release potassium (duodenal ulcers — prescription only for a reason); potassium products marketed as "high-dose" circumventing FDA limits
Minimum effective dose: Food-first approach — 4,700mg/day total from diet. Supplements bridge the gap.
Third-party tested brands: NOW Foods (potassium citrate), Nature Made, Life Extension
