Liquid Vitamin D3 2,000IU Mint Flavor 1 Ounce Life Extension
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.
The current RDA for vitamin D is only 600 IU which has resulted in startling evidence of a widespread deficiency for this vitamin. Most experts in the field now recommend intakes between 1, 000 - 10, 000 IU for adults to achieve a serum 25(OH)D level above those indicative of vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.
Life Extension suggests that healthy adults supplement each day with 5000-8000 IU of vitamin D with the objective of achieving an optimal 25-hydroxy vitamin D blood level between 50-80 ng/mL. A vitamin D blood test can help you determine the amount of vitamin D you need to supplement to achieve an optimal level.
