Manganese is a required cofactor for an enzyme called prolidase, which is in turn necessary to make collagen as a structural component of skin. This role of manganese in collagen production makes this mineral important for everyday skin health.
Manganese is a ubiquitous element that is essential for normal physiologic functioning in all animal species. Several disease states in humans have been associated with both deficiencies and excess intakes of manganese. Thus any quantitative risk assessment for manganese must take
