controversy over the Institute of Medicine's new recommendations (RDA) for vitamin D and calcium
You'll hear controversy over the Institute of Medicine's new recommendations (RDA) for vitamin D and calcium. They call for MORE vitamin D and LESS calcium...but many experts say the vitamin D doses are still not high enough.
Vitamin D. The new RDA is 600 IU for people up to age 70...and 800 IU for those over 70. But keep in mind that the RDA is set at the amount needed to prevent rickets and osteomalacia.
Higher amounts of vitamin D are associated with a lower risk of falls, cancer, heart disease, autoimmune disorders, etc. But the RDA is not set higher because there's not sufficient proof of a benefit.
