Minerals and trace elements - Manganese
Manganese is required for bone formation and for energy metabolism. It is also a constituent of an antioxidant enzyme, which helps prevent free radical-mediated damage to cells.
Manganese deficiency is rarely seen.
Manganese toxicity is not a problem because blood levels are carefully controlled.
It is present in plant foods such as vegetables, cereals and nuts. Tea is also a rich source. In the UK, 50% of manganese intake is derived from cereals and cereal products.
