Thorne Research, Vitamin D3 1000 IU 90 veggie caps

It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age. Vitamin D helps protect the body from bone disease and myriad other health conditions. Current vitamin D intake requirements are based on minimum allowances to protect against bone disease. These guidelines are now being revised upward in light of new research, especially pertaining to immune function. Cutting edge research suggests serum vitamin D levels should be in the range of 33-80 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, latitude, or lifestyle. Therefore, vitamin D supplementation can be of great benefit in these cases.

While several factors contribute to decreased bone density and increased fracture rate, vitamin D deficiency/insufficiency clearly represents a significant factor. In a 2007 case-controlled study of the Women’s Health Initiative Observational Study Cohort, women with the lowest levels of
vitamin D (serum 25(OH) vitamin D less than 19 ng/mL) were found to have a 77-percent higher risk of hip fracture than women with the highest vitamin D level (average 28 ng/mL – which is still considered low). The amount of vitamin D needed to achieve minimum vitamin D sufficiency (commonly defined as a 32 ng/mL 25(OH)D blood level) depends on many factors and can vary significantly from individual to individual. Thus, the requirement for vitamin D supplementation needs to be individualized.

Thorne’s D-1000 supplies 1,000 IU of pure, vitamin D3 in each vegetarian capsule. This potency is ideal for maintaining optimum vitamin D levels in healthy individuals.
