Manganese health

Manganese is an essential trace element for humans. The average adult body contains between 12 and 20 mg with the highest concentrations in the bones, liver, kidneys and heart.

Benefits

Manganese appears to be involved in many enzyme systems, although its functions are not well understood. It acts as a co-factor for enzymes necessary for energy production and is involved in glucose metabolism, the stimulation of glycogen storage in the liver, protein digestion and cholesterol and fatty acid synthesis. It is also necessary for the synthesis of DNA and RNA.

Manganese is necessary for growth, maintenance of the nervous system, the development and maintenance of healthy bones and joints, the formation of blood clotting factors, female sex hormone function and thyroid hormone function.

Manganese healthSuperoxide dismutase

One form of the antioxidant enzyme, superoxide dismutase, contains manganese. Proper function of this enzyme helps protect against free radical damage. (See page 417 for more information.) Laboratory studies have shown that it can protect brain cells from the type of damage seen in stroke and Alzheimer's disease. It may also help to protect against liver damage. Manganese superoxide dismutase levels are higher in alcoholics and may help to protect against oxidative damage by alcohol.

Absorption and metabolism

Only 3 to 5 per cent of dietary manganese is absorbed. After absorption, manganese is transported to the liver.

Manganese healthRecommended dietary allowances

Suggested daily intake ranges from 2 to 5 mg. Such amounts are easily obtained from diets high in whole grains and vegetables.
