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.
Over-the-counter and prescription supplements can increase your vitamin D3 intake. The amount of vitamin D necessary for good health is a matter of sharp debate. The Food and Nutrition Board's adequate intake amount is 600 IUs per day between the ages of 1 and 70 and 800 IUs per day for adults over age 70.
