Manganese is an essential nutrient that is involved in a number of bodily reactions affecting the metabolism of amino acids, cholesterol, and carbohydrates. Manganese is also involved in bone and joint formation. It plays a role in collagen production, blood clotting, brain function, reproduction, and natural bodily defenses. In adults the body contains around 15 milligrams of manganese that is spread throughout the liver, kidneys, and bones.
