Recommended Daily Allowance for Vitamins for Men 31 to 50 Years Old. According to the Food and Nutrition Board of the Institute of Medicine, the RDAs for fat-soluble vitamins for men are as follows: Vitamin A is 900 micrograms, vitamin D is 15 micrograms, and vitamin E is 15 milligrams.
However, experts suggest that the Institute of Medicine's current recommended daily intakeâ600 IU for men and womenâis simply too low. Optimal blood levels of vitamin D to reduce your risk of disease is 28 to 42 ng/mL, says Joel Fuhrman, MD, author of Super Immunity.
