nutrient
Manganese
A trace mineral that activates enzymes involved in metabolism, antioxidant defence, bone formation and connective tissue.
Educational draft · Human scientific and editorial review pending. About review status
Manganese is present in grains, nuts, legumes and tea. The body regulates absorption and excretion, but high supplemental exposure can create a different safety context from food.

How it works
What it does
Manganese is a cofactor or activator for enzymes including manganese superoxide dismutase and enzymes involved in carbohydrate, amino-acid and cholesterol metabolism. It also supports connective-tissue and bone formation.
Where it comes from
Whole grains, nuts, legumes, leafy vegetables and tea can contribute manganese.
Roles and processes
Manganese supports formation of Bone
Manganese-dependent enzymes participate in bone and connective-tissue formation.

Worth knowing
Many plant foods contribute. Whole grains, nuts, legumes, leafy vegetables and tea can provide manganese. The amounts vary between foods and preparation methods.
A closer look
Concentrated manganese has a different risk context
The body regulates manganese absorption and excretion, but high supplemental exposure can affect the nervous system, especially in susceptible settings. A food reference value does not justify a high-dose product.
