Micronutrient Nutrition for Older Adults
Listed below are vitamin and mineral dietary intake recommendations for individuals over the age of 50 years. For each micronutrient, the Food and Nutrition Board of the Institute of Medicine establishes a recommended dietary allowance (RDA) or adequate intake (AI). Generally, the Linus Pauling Institute supports the recommendations of the Food and Nutrition Board, but any discrepancies in dietary recommendations are listed in the rightmost column of the table. Additionally, more information on the Linus Pauling Institute recommendation for a specific micronutrient can be found by clicking on the name of the micronutrient of interest.
