Amount Per Serving |
|
Vitamin D3 (as cholecalciferol) |
1000 IU |
Other ingredients: safflower oil,
gelatin, glycerin and purified water.
Dosage and Use
Take one softgel daily with food, or
as recommended by a healthcare practitioner.
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.
For most people, this 1,000 IU potency is
insufficient to attain optimal vitamin D blood levels. For smaller
individuals who obtain 2,000-3,000 IU in their multi-nutrient formulas
(and children), this potency of vitamin D may be suitable.

Vitamin D3
1,000 IU 250 softgels
Item# 01751 |
Vitamin D has long provided significant support
for healthy bone density. 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. These findings link a deficiency of vitamin D to a host
of common age-related problems.
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, skin tone 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.
The current RDA is only 600 IU. As a result of
startling evidence of a 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. Currently, most experts
in the field believe that intakes of between 1,000 and 10,000 IU for
adults will lead to serum 25(OH)D levels above those indicative of
vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.
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 between 50-80 ng/mL.
Vitamin D in the amount of 2,000 IU is contained
in the multi-nutrient Life Extension Mix™ and the multivitamin
Two-Per-Day Tablets. A vitamin D blood test can help you determine the
additional amount of vitamin D you may need to supplement to achieve an
optimal level.
For most people, this 1,000 IU potency is
insufficient to attain optimal vitamin D blood levels. For smaller
individuals who obtain 2,000-3,000 IU in their multi-nutrient formulas
(and children), this potency of vitamin D may be suitable.
