THORNE RESEARCH - Vitamin D-25,000 - 60ct [Health and Beauty]
Thorne Research D-25,000, 60 Vegetarian It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age. Vitamin D helps protect a number of important functions in the body. The current recommended daily vitamin D intake is 200-600 IU, and is based on the minimum allowance to protect against bone disease. However, an upward revision of the FDA's guideline is now under consideration in light of new research, especially pertaining to immune function. Cutting-edge research suggests serum vitamin D levels should be in the range of 32-80 ng/mL 25-hydroxyvitamin D (25(OH)D). Although direct sunlight exposure is a good source of vitamin D, many people do not get enough sun due to season change, latitude, or lifestyle. Therefore, vitamin D supplementation can be of great benefit in these cases. Individuals deficient in vitamin D may need 5,000-10,000 IU of vitamin D daily to replenish tissue stores. Other individuals who may need higher doses of vitamin D include the obese (the more a person weighs, the greater their vitamin D requirements), individuals with chronic disease, darker-skinned populations, and those with fat malabsorption. Some individuals respond well to an initial loading dose of 25,000-50,000 IUs for several days to a week, followed by lower maintenance dosing. With these individuals specifically in mind, Thorne's D-25,000 supplies 25,000 IU of pure vitamin D3 in each vegetarian capsule. Short-term (2-3 days) high-dose vitamin D may also support healthy immune function.
