    The requirement for vitamin D supplementation needs to be individualized. 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 of 400 IUs is based on the minimum allowance to protect against bone disease. Thorne Research's D-1,000 supplies 1,000 IU of vitamin D3 in each vegetarian capsule. This potency is ideal for maintaining optimum vitamin D levels in healthy individuals.
