Vitamin D protects a number of important functions in the body.* In addition to supporting healthy bones and muscles, it supports cardiovascular health and immune function.* Although direct sunlight provides natural vitamin D, many individuals of all ages, especially the elderly, do not get enough vitamin D from sunlight and their diet. 

Vitamin D supplementation can be of great benefit in these situations.* However, the powders used in many pre-mixed vitamin D dilutions frequently contain potentially detrimental ingredients such as lactose, as well as preservatives such as BHT, BHA, sodium benzoate, and sorbic acid. Thorne's vitamin D is formulated for individuals who are sensitive to those ingredients.

The amount of vitamin D needed to achieve minimum vitamin D sufficiency – generally recognized to be a blood level of 32 ng/mL of 25-hydroxyvitamin D – depends on many factors and varies from individual to individual. Thus, the requirement for vitamin D supplementation should be individualized.
