What is it?

Manganese is a trace mineral needed for formation of bone and joint tissue; production of the antioxant SOD; immune function; nervous and reproductive systems; stimulation of glycogen production.

Function How it helps
Connective tissue health

Manganese facilitates the synthesis of both collagen and mucopolysaccharides, the two primary structural components of all connective tissue. Manganese is also involved in the proper development of the hard structures of the inner ear that are responsible for maintaining balance/equilibrium.

Antioxidant Manganese is an essential mineral component of the enzyme superoxide dismutase (SOD). SOD is an antioxidant which prevent free radical damage to tissues.
Joint health Manganese plays a significant role in joint integrity, including within the vertebral discs, due to its involvement in cartilage and bone growth and stability.
Gluose metabolism Manganese is a component of various enzymes that catalyse the metabolism and utilisation of glucose, critical in the maintenance of blood sugar control.

Other information

Manganese is usually taken in combination with other bone nutrients, calcium, magnesium, zinc and boron. It is often used to treat minor wounds and help regulate blood sugar levels.



  • Although standard doses of manganese found in supplements are unlikely to cause side effects or toxicity, very high levels of exposure (usually from environmental or occupational exposure) can lead to many symptoms of manganese toxicity, such as symptoms resembling Parkinson’s Disease and Wilson’s Disease, irritability, depression, insomnia, hallucinations, delusions, violent acts, defects in motor function, loss of appetite, impotence, weakness, difficult breathing and leg cramps.

  • Patients suffering from Parkinson’s Disease or Wilson’s Disease should only take manganese on the advice and under the strict monitoring of a doctor.

  • High intakes of manganese may interfere with the absorption of iron, zinc and copper. If suffering with iron-deficiency anaemia, it is advisable to consult a qualified healthcare practitioner before taking a manganese supplement.



Factors which deplete levels, impair absorption and/or inhibit activity:

Calcium, copper, iron, magnesium, zinc at very high intake levels



Oral contraceptives
