BioStacksHow Potassium supports heart
When it comes to heart, Potassium is one of the most supporting nutrients to consider. Primary intracellular electrolyte essential for maintaining fluid balance, nerve impulse transmission, and muscle contraction—including cardiac rhythm. Works in opposition to sodium: higher potassium intake helps lower blood pressure by promoting sodium excretion. The FDA limits over-the-counter potassium supplements to 99 mg per dose due to risk of GI irritation; most dietary potassium should come from foods like bananas, potatoes, and leafy greens.
How much potassium do you need
Research points to 200–500 mg as the effective range for potassium. Supplemental range; FDA limits OTC potassium to 99mg/dose. Most dietary potassium comes from food. Lower doses may provide some benefit, but most studies showing clear results used this range.
Clinical research
Potassium has strong clinical evidence for heart benefits. Multiple trials confirm blood pressure reduction via sodium excretion; FDA limits supplements to 99mg/dose Learn more
