Fact 2 of 9
The U.S. National Academy of Sciences' Food and Nutrition Board has issued a Recommended Daily Allowance (RDA) of 0.9 mg of copper per day for both men and women between the ages of 19 and 70. Copper is an especially important nutrient for expectant mothers and developing fetuses (1.0 mg per day), as well as nursing mothers and newborns (1.3 mg per day). Children between 9 and 18 need only 0.7 mg to 0.89 mg per day. The U.S. Department of Agriculture's Nutrition Center estimates that less than half of the U.S. population consumes the MDR for copper.
