Where is manganese found in the body?

The human body contains about 10 to 20 mg manganese, of which 25% to 40% is in bone [1,2]. The liver, pancreas, kidney, and brain also contain manganese. The body maintains stable tissue manganese concentrations through regulatory control of manganese absorption and excretion [5].

What does manganese do to the body?

Manganese is a trace mineral that is present in tiny amounts in the body. It is found mostly in bones, the liver, kidneys, and pancreas. Manganese helps the body form connective tissue, bones, blood clotting factors, and sex hormones.
