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. However, an upward revision of the FDAs 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.

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 Vitamin 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.
