Known as the sunshine vitamin, one of the key roles of vitamin D is maintaining serum calcium and phosphorous balance. The body makes vitamin D by converting vitamin D2 to D3, or cholecalciferol, when the skin is exposed to sunlight. Vitamin D supplements come in two forms, D2 and D3. Studies have found vitamin D3 is the preferable form, as it has been found to maintain active vitamin D levels for a longer period of time.

The Vitamin D formula is delivered as D3 (cholecalciferol) for optimal use by the body, and is available in 1,000 and 5,000 IU capsules to meet a variety of individual needs.

Suggested Use:

1 or more capsules per day or as recommended by your health care professional.
