manganese minerals have been known since the days of the Roman naturalist Pliny, who referred to the black stone for the bleaching of the glass mass.In 1774, Swedish scientist Yu Gang received manganese by heating a mixture of pyrolusite with coal.The name itself comes from him.«Manganerz» - «manganese ore."

This trace element is always present in living organisms and simply indispensable for their full life.Plants and animals need it for normal growth and reproduction.For a man it is important for the activation of several enzymes, the synthesis of proteins, fats and carbohydrates for mineral metabolism.

healthy adult human body contains 10-15 mg of manganese.The greatest concentrations are found in the bones, liver, brain, pancreas, kidneys.

How does the manganese on human health?


  • affect the development of the skeleton;
  • involved in the process of lipid and carbohydrate metabolism, bone formation;
  • promotes normal blood formation and tissue respiration, supports the activities of the reproduct
    ive system;
  • is located in a part of the active site of enzymes that are important in the redox processes (pyruvate kinase, and superoxide dismutase);
  • Promotes connective tissue, normal bone and cartilage;
  • necessary for the nervous system and brain, and nucleotide synthesis of cholesterol;
  • prevents excessive deposition of fat tissue, maintain normal blood sugar levels, reduces it by diabetes;
  • regulates blood glucose and essential for the synthesis of insulin, helps the absorption of ascorbic acid.

as interactions with other substances?



assimilation of manganese is reduced by an excess of iron, together with copper and zinc, a trace mineral that acts as an antioxidant.
