Potassium magnesium citrate is a single supplement that delivers two essential minerals—potassium and magnesium—bound to citrate, a natural base. Taken daily, it supports several parts of the body at once.

Muscles and nerves work best when their electrical signals fire smoothly. Potassium sends those signals, while magnesium helps stop cramps; together they keep your muscles contracting and relaxing on cue.

PMC also protects bones. A Western diet can leave the body slightly acidic, and bones “lend out” minerals to neutralize that acid. By supplying an alkaline citrate salt, PMC eases the acid load and slows the normal breakdown‑and‑build cycle of bone, a benefit confirmed in studies of people stuck in bed or eating high‑acid diets.

For the heart, potassium blunts the blood‑pressure‑raising effect of excess sodium, and magnesium relaxes blood‑vessel walls. Clinical work shows the combination can trim fasting blood‑sugar levels and make arteries less stiff—two wins for long‑term cardiovascular health.

Because the citrate form is easy to absorb, PMC delivers potassium as effectively as potassium chloride but supplies magnesium far better, with fewer stomach upsets than plain potassium citrate. That high absorption, plus the added citrate, explains why PMC outperforms chloride or plain citrate salts in head‑to‑head tests.
