Vitamin D3

Vitamin D has long provided significant support for healthy bone density. However, scientists have validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and has profound effects on human immunity.

Vitamin D is synthesized in the body from sunlight. But, due to the winter season, weather conditions, and sunscreen blockers, the body's ability to produce optimal vitamin D levels may be inhibited. In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza. All of these factors point to the value of taking a daily vitamin D supplement to ensure optimal vitamin D intake.

Just one capsule a day supplies 1000 IU of vitamin D3 (cholecalciferol), a form of the vitamin that is identical to that derived from sunlight on the skin.
