The Ecology of Humans (47-5) Magnesium


Magnesium is highly reactive. That quality is key to magnesium’s biological value.

Magnesium is abundant in the body. Half of the magnesium in our bodies is stored in the bones.

Over 300 enzyme systems employ magnesium as a cofactor to regulate biochemical reactions, including energy (ATP) production and protein synthesis. Magnesium is needed for proper muscle, circulatory, immune and intelligence system functioning.

Coupled with phosphate, magnesium drives basic nucleic acid chemistry. Magnesium is active in the transport of calcium and potassium ions across cell membranes.

Magnesium competes with calcium. For good health, magnesium, calcium, and potassium must stay in balance at sufficient levels. Excess magnesium is readily filtered by the kidneys and eliminated in urine.

Rich dietary sources of magnesium include green leafy vegetables, beans, nuts, and seafood.
