Within the last decade, Vitamin D has rapidly gone from a relatively obscure and overlooked nutrient to the subject of intensive research and study as scientists continue to identify important new roles for this nutrient. Vitamin D supports the health of the whole body, but is of particular importance to the immune system and bone health.The trouble is, unless you're out in the sun everyday, your body simply can't make enough vitamin D, and no matter what your diet is, it doesn't supply much vitamin D.

In fact, the recommended amounts have been creeping upwards, with the 2000 IU products like NOW Foods Vitamin D rapidly overtaking the lower potency 1000 IU and 400 IU products.
