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 major role of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D helps the body absorb calcium, which forms and maintains strong bones. It is used alone or together with calcium to improve bone health and decrease fractures. Vitamin D may also protect against osteoporosis, high blood pressure, cancer, and other diseases.
