A role for vitamin D in inflammation is supported by studies in laboratory animals. In particular, mice lacking the vitamin D receptor or the vitamin D activating enzyme, 25-hydroxyvitamin D3-1-hydroxylase, have increased susceptibility to inflammation, especially inflammation of the gastrointestinal tract (61-63).
Vitamin D promotes calcium absorption, and it is needed for bone growth. It also has a positive role in the function of the immune system and reduces inflammation. Women aged 19 to 70, pregnant or nursing are required to get 600 international units, or 15 micrograms, of vitamin D. After age 70, the RDA for vitamin D is 800 IU, or 20 micrograms.
