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, to obtain the benefits of the vitamin, you must take 700 to 1000 IU a day. These studies buttress other research that has shown that vitamin D improves strength, balance and bone health in the elderly. Each year, one third of people 65 and older, and one half of people 50 and older fall at least once.
