FOUR BOTTLES FRESH PRODUCT! SHIPS TO YOU STRAIGHT FROM LIFE EXTENSION! BUY IT NOW AND SAVE! Vitamin D3 1,000 IU, 250 softgels 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. 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. 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. SUPPLEMENT FACTS Supplement Facts Serving Size 1 softgel Amount Per Serving Vitamin D3 (as cholecalciferol) 1000 IU Other ingredients: extra virgin olive oil, medium chain triglycerides oil, gelatin, glycerin, purified water, rosemary extract. Non-GMO Dosage and Use Take one (1) 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.
