Manganese is an element that is part of many tissues. It is mainly stored in the liver, brain, kidneys and pancreas.

Manganese is a component of many enzymes, it participates in the process of proper digestion and absorption of carbohydrates, fats and proteins. It takes part in the action of enzymes necessary for the body to properly absorb biotin (vitamin B7), vitamin B and vitamin C. In addition, it is responsible for the proper functioning of the nervous system and has a strong influence on the level of libido, sexual performance and fertility. It is an element necessary to maintain healthy bones.

Manganese affects the skin’s good condition and plays an important role in the production of thyroxine, an inactive form of thyroid hormones. Manganese facilitates the absorption and storage of iron.

Apart from zinc and copper, manganese is included in the superoxide dismutase (SOD) enzyme – a powerful antioxidant produced by the body to protect cells, tissues and essential physiological compounds from damage caused by free radicals.
