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 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!Ratings based on results of the 2016 ConsumerLab.com Survey of Supplement Users.

|Dosage and Use|
Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.
