Potassium

mineral Unit: mg

Potassium is the principal positively charged ion inside cells and is essential for maintaining membrane potential in nerve and muscle cells, regulating heart rhythm, and counteracting the blood-pressure-raising effect of sodium. The adequate intake is 2,600–3,400 mg per day; most adults do not meet this target. Fruits, vegetables, legumes, and dairy are the best dietary sources.
