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.*
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.*
Vitamin D deficiency is quite common, particularly among the elderly.* For example, a study conducted at a hospital in Glasgow, Scotland, found an almost universal vitamin D deficiency among a group of 548 elderly patients. Individuals deficient in vitamin D may need 2,000-5,000 IU of vitamin D daily to replenish tissue stores.* With these individuals specifically in mind, Thorne's D-1,000 supplies 1,000 IU of pure vitamin D3 in each vegetarian capsule.
