Manganese Deficiency
Introduction
Manganese(Mn), necessary for healthy bone structure, is a component of several enzyme systems, includingmanganese-specific glycosyltransferases and phosphoenolpyruvate carboxykinase. Median intake is between 1.6 and 2.3 mg/day; absorption is 5 to 10%. Manganesedeficiencyhas not been conclusively documented, although one experimental case in a volunteer resulted in transient dermatitis, hypocholesterolemia, and increased alkaline phosphatase levels.
