Manganese is a gray-white metal, resembling iron. The classes of enzymes that have manganese cofactors are very broad and include such classes as oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, lectins, and integrins.
Forms part of the enzyme copper-zince superoxide dismutase (CuZn SOD) system.
Rich Food Sources of Manganese
The largest quantities of manganese are found in avocados, nuts and seeds, seaweed, and whole grains. This mineral may also be found in blueberries, egg yolks, legumes, dried peas, pineapples, and green leafy vegetables.
Benefits and Functions of Magnanese
Manganese is essential for proper coordination between brain and body. Too little manganese may result in abnormal muscular movements, bad balance or muscular twitching. It may be useful for the treatment of male and female sterility, impotence in men, digestive disorders, convulsions or seizures. Manganese may be of some value to expectant mothers, because of its association with the maternal instinct and its action in maintaining healthy glands, including the mammary glands.
Taking 4 mg or less of manganese supplements a day is unlikely to cause any harm. For older people, taking 0.5 mg or less of manganese supplements a day is unlikely to cause any harm. This is a lower amount because older people may be more sensitive to manganese.
What are the deficiency symptoms of Magnanese?
Deficiencies are unusual but may lead to:
Rashes & skin conditions;
Reduced hair growth;
Retarded growth (in children).
Overdosage Signs of Magnanese
Excessive intake has been associated with brain conditions such as symptoms similar to those resulting from Parkinson's disease.
Taking high doses of manganese for long periods of time might cause nerve damage and neurological symptoms such as fatigue and depression.
