Understanding Vitamin D Supplementation
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.
As a result of evidence of widespread vitamin D deficiency, prominent nutritional scientists are calling on Americans to increase their vitamin D intake to 1000 IU per day and higher. Life Extension recommends that healthy adults supplement each day with at least 2000 IU of vitamin D. Elderly adults may benefit from higher doses such as 5000 IU daily up to 10000 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).
Why Choose Life Extension Vitamin D3 Over Others?
Commercial companies offered only 400 IU vitamin D products when Life Extension long ago introduced its 1000 IU version. It has since added dosages as high as 5000 IU and 7000 IU. For most people, a 1000 IU potency is insufficient to attain optimal vitamin D blood levels, but others may require larger dosages in order to get the same effect.
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.
Caution: 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.
