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. These factors point to the value of taking a daily vitamin D supplement.

Benefits at a Glance:

• Supports healthy bone density
• Encourages healthy cell differentiation
• Promotes healthy immune function
• Shown to increase vitamin D blood levels with daily use
• Perfect for those whose multivitamin already contains vitamin D

Supports bones, cellular health, and immune function

Vitamin D has long provided significant support for healthy bone density.^1-7 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.^8-14 These findings link a deficiency of vitamin D to a host of common age-related problems.

Getting enough vitamin D

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 an intake 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 5,000–8,000 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 additional amount of vitamin D you may need to supplement with to achieve an optimal level.

Complements multivitamins with vitamin D

If your calcium supplement or multivitamin also contains vitamin D3, this softgel is an excellent way to complement that intake and reach an optimum blood level of D3 for whole-body health!
