Recommended intake of vitamin D
The U.S. recommended daily allowances (RDAs) for vitamin D are 200 IU (birth to age 50), 400 IU (age 51-70) and 600 IU (age 71-plus).
Substantial peer-reviewed evidence supports leading researchers' recommendations that the U.S. Institute of Medicine raise the U.S. RDAs substantially.
To help ensure optimal health, most researchers involved in vitamin D studies recommend minimum blood levels ranging from 90 to 120 nmol/L (36 to 48 ng/mL),and normal human blood levels* of vitamin D extend above 200 nmol/L (80 ng/mL).
Though the official upper intake limit is now 2,000 IU per day, vitamin D intake is proven safe* at a daily intake level of 10,000 IU ... which is 25 times the current RDA for adults 51 or older (400 IU).
Most experts say that the evidence supports a daily intake of at least 1,000 IU via food and supplements, and most prefer an intake of 2,000 IU to 4,000 IU per day*. This intake level applies to all people, but is especially advised for darker skinned people who spend less than 30 minutes per day in strong sunlight.
Darker skinned people, whose greater amount of skin pigment blocks the UV rays that make vitamin D, need more sun exposure. You will find more information in an article by vitamin D researcher professor Edward Giovannucci, M.D., Sc.D., of Harvard University's School of Public Health.
