Manganese is a trace element that acts as a powerful antioxidant in mitochondria (MnSOD). How manganese protects cells from oxidative stress and supports joint health in athletes.

Manganese is a trace element that acts as a cofactor for many important enzymes: manganese superoxide dismutase (MnSOD — mitochondrial antioxidant), pyruvate carboxylase (gluconeogenesis) and arginase (urea cycle). For athletes, manganese is important for antioxidant protection, bone formation and carbohydrate metabolism. MnSOD is the main antioxidant in mitochondria — the cell's energy powerhouses.
MnSOD is the main antioxidant in mitochondria, neutralizing superoxide radicals, whose production increases 10-20 times during training. This protects the cell's energy production centers.
Manganese is essential for the synthesis of glycosaminoglycans — components of cartilage and synovial fluid. This helps maintain healthy joints, especially for runners and weightlifters.
Manganese participates in gluconeogenesis (new glucose production) and the insulin signaling pathway. Sufficient manganese intake helps maintain stable sugar levels.
Manganese participates in the metabolism of neurotransmitters (dopamine, glutamate). This is important for motor coordination and reaction speed.

True manganese deficiency is rare because typical diets contain enough of it. However, athletes with a very restricted diet (e.g., vegans without nuts and grains) may be at risk.
Yes, together with glucosamine and chondroitin, manganese is one of the three most commonly used components of joint supplements. It helps synthesize proteoglycans — structural components of cartilage.
From food — practically impossible. From supplements — yes, especially if you take more than recommended. Manganese toxicity manifests as neurological symptoms similar to Parkinson's disease. Stick to the recommended doses.
