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.
The current daily value for vitamin D is 10 micrograms or 400 units, according to the Office of Dietary Supplements. A milk label that states an 8-ounce serving provides 25 percent of your daily value therefore contains 2.5 micrograms, or 100 international units, of vitamin D.
