Product Description

Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight. But, due to the winter season, weather conditions, and sun block, the body’s ability to produce optimal vitamin D levels may be inhibited.70 In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza.71 All of these factors point to the value of taking a daily vitamin D supplement.

Vitamin D has long provided significant support for healthy bone density.72-77 However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity.78-81 These findings link a deficiency of vitamin D to a host of common age-related problems.

The current RDA is only 600 IU. As a result of startling evidence of a widespread vitamin D deficiency, prominent nutritional scientists are calling on Americans to increase their vitamin D intake to 1,000 IU per day and higher. Currently, most experts in the field believe that intakes of between 1,000 and 10,000 IU for adults will lead to serum 25(OH)D levels above those indicative of vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.

Life Extension recommends that healthy adults supplement each day with at least 2,000 IU of vitaminD. Elderly adults may benefit from higher doses such as 5,000
