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 screen usage, the body's ability to produce optimal vitamin D levels may be inhibited.1 These factors point to the value of taking a daily vitamin D supplement.

Vitamin D has long provided significant support for healthy bone density.2-7 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.8-15 These findings link a deficiency of vitamin D to a host of common age-related problems.

As a result of evidence of 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. Life Extension recommends that healthy adults supplement each day with at least 2,000 IU of vitamin D. Elderly adults may benefit from higher doses such as 5,000 IU daily up to 10,000 IU daily. The objective of taking a vitamin D supplement is to achieve an optimal 25-hydroxy vitamin D blood level of 50 ng/mL (and higher).

Vitamin D in the amount of 2,000 IU is contained in the multinutrient Life Extension Mix and the multivitamin Two-Per-Day tablets. A vitamin D blood test (available online or by calling the Life Extension Blood Lab at 1-800-208-3444), can help you determine the additional amount of vitamin D you may need to supplement to achieve an optimal level.

For those already obtaining 1,000-3,000 IU of vitamin D in their multinutrient formulas, this 5,000 IU potency is what many need to achieve optimal vitamin D blood levels.

Life Extension has upgraded its vitamin D capsules to a small, easy to swallow softgel form that does not include allergen ingredients or vegetable stearate.
