Product Information

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 FDA's 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 D-1,000 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.*

Some vitamins, because of their potency, are usually given in very small amounts. Examples of such "micro-dose" vitamins include vitamin D, vitamin K, and vitamin B12. Most dietary supplement manufacturers purchase "micro-dose" vitamins from raw material suppliers as premixed dilutions, meaning the vitamins (in powder form) are mixed with other powdered substances that in turn make it easier for the manufacturer to handle and mix a larger quantity of raw material. Unfortunately, the powdered substances used in these premixed dilutions frequently contain potentially detrimental ingredients such as lactose and also the preservatives BHT, BHA, sodium benzoate, and sorbic acid.

At Thorne Research, our promise is to give you the purest supplements humanly possible. Therefore, we do not purchase premixed dilutions of any "micro-dose" vitamins. Instead, we purchase pure, undiluted vitamins and create our own dilutions when it is necessary to do so, using pure, hypoallergenic powders, such as magnesium citrate or plant cellulose The resultant premixture is then added to the dietary supplement being made, ensuring the proper amount of each pure nutrient is contained in each capsule.
