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.
How much vitamin D should adults take? According to the National Institutes of Health (NIH), the daily Adequate Intake (AI) for adults is 5 mcg (200 IU) daily for males, female, and pregnant/lactating women under the age of 50. People 50 to 70 years old should get 10 mcg daily (400 IU) daily, and those over 70 should get 15 mcg daily (600 IU). Based on recent research, Dr. Weil recommends 2,000 IU of vitamin D per day. Look for supplements that provide D3 (cholecalciferol) rather than D2 (ergocalciferol).
