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.
Between age 50 and 70 the adequate daily intake is 400 IU for men and women. After age 70 the adequate intake is 600 IU for men and women. Because seniors are at greater risk for vitamin D deficiency, there have been many recent studies to determine if vitamin D supplements are useful in preventing falls and fractures.
