In the US, estimated average dietary manganese intakes range from 2.1 to 2.3 mg/day for men and 1.6 to 1.8 mg/day for women. People eating vegetarian diets and Western-type diets may have manganese intakes as high as 10.9 mg/day (4). Rich sources of manganese include whole grains, nuts, leafy vegetables, and teas.
1. Manganese (Mn) is an essential trace element that is found in varying amounts in all tissues. Manganese concentrations are highest in tissues rich in mitochondria, where it forms stable complexes with ATP and inorganic phosphate. Manganese functions as a constituent of metalloenzymes and an activator of enzymes. key neurochemical alteration associated with manganese neurotoxicity is altered extracellular glutamate levels. Attenuated glutamate uptake by astrocytes has been invoked as the primary cause for this disturbance (Hazell and Norenberg, 1997 and Erikson and Aschner, 2002).
