Manganese is an essential nutrient that activates a number of enzymes involved in the formation of bone and in amino acid, lipid and carbohydrate metabolism. Dietary manganese can be found in grain products, vegetables and beverages such as tea. Only a small percentage of dietary manganese is absorbed through the intestine 1.
The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 2.0 mg manganese for adults and children 4 or more years of age (21CFR101.9). RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.
