Health Effects of Manganese

Function

Manganese is essential for bone formation, blood clotting, carbohydrate metabolism, and antioxidant defense (as part of manganese superoxide dismutase). It activates many enzymes.

Deficiency Signs

Manganese deficiency is rare. Experimental deficiency causes impaired growth, skeletal abnormalities, altered carbohydrate and lipid metabolism, and impaired reproductive function.

Excess / Toxicity

Inhaled manganese (occupational) is neurotoxic (manganism). Dietary excess is rarely problematic due to tight homeostatic control. UL is 11mg/day for adults.

Absorption & Interactions

How It’s Absorbed

Absorbed in the small intestine at 1-5% efficiency. Absorption is regulated by body stores and is inhibited by iron (shared DMT1 transporter). Excreted primarily via bile.

Key Interactions
Iron Inhibitor
Iron and manganese compete for the DMT1 transporter; high iron status reduces manganese absorption
