The main food sources of manganese in the U.S. diet are tea, vegetables, and whole grains. Manganese is a component of an antioxidant called superoxide dismutase (SOD), which can protect against cell damage caused by free radical molecules. SOD is an enzyme that breaks down the free radical superoxide into smaller, less harmful molecules.
