The main function of manganese is to activate enzymes, the body's catalysts, without which our biochemical processes could not work. For example, manganese is an essential component of the enzyme processes in both cholesterol synthesis and the synthesis of cartilage and bone.

Therefore, it isn't surprising that manganese is critical for your growth, reproduction and skeletal development. It is also an important part of the synthesis of interferon, a natural anti-viral agent your body uses to defend itself when attacked by disease-producing viruses and it is critical for a healthy nervous system.

Manganese is not easily absorbed from food or supplements. If your nutritional score indicates a manganese deficiency, add more manganese-rich foods to your diet daily. Good sources are lentils, beans, brown rice, whole grains, dark green leafy vegetables, almonds, many spices, nuts and blueberries. However, manganese content varies depending on the location in which food is grown. Do not eat excessive amounts of wheat or oat bran, as they contain a substance which prevents absorption of manganese. Take a good multivitamin/mineral capsule (which includes manganese) on a daily basis.
