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 safe upper limit for vitamin D is 1,000 to 1,500 international units (IU) per day for infants. For children aged one to eight years, the safe upper limit is 2,500 to 3,000 IU/day, and 4,000 IU/day for children nine years and older, adults and pregnant and lactating teens and women.Excessive sun exposure will not cause vitamin D poisoning because the body limits the amount of this vitamin it produces.ome experts suggest that men and women over fifty take 800 IU of vitamin D year-round. Check with your VA doctor to see how much vitamin D you need. The usual recommended dietary allowance (RDA) for vitamin D is 400 IU.
