Vitamin D has recently gained the attention of many researchers, and information on it has increased greatly. The number of articles in Medline, the National Library of Medicine's online database, has increased from 2,766 articles in 2000 to 7,039 articles in 2009. This increased information has broadened our knowledge of vitamin D, which functions as a hormone regulating calcium metabolism and supporting cardiovascular health, bone and muscle function, and immune function.* Epidemiological studies are showing higher serum vitamin D levels are associated with a healthier lifespan.*

A Vitamin From the Sun

Humans make vitamin D from exposure to ultraviolet radiation from the sun (or tanning beds). A cholesterol-like molecule, 7-dehydrocholesterol, is converted in the skin to a pre-vitamin D molecule, which is then converted to 25-hydroxy vitamin D [25(OH)D] in the liver. This form of vitamin D is converted when necessary to active 1,25-dihydroxy vitamin D. Laboratory tests of serum 25(OH)D can detect when the body has a sufficient amount of vitamin D.

Why Supplement With Vitamin D?

Most experts agree that a level of greater than 30 ng/mL of serum 25(OH)D is necessary for vitamin D to exert its benefits on all tissues; however, some researchers advocate that higher levels may be needed, claiming an optimal serum level might be 40 ng/mL or higher.* Dietary sources are too low to be beneficial, and most people do not get enough sun exposure, so supplementation is necessary.

How Much is Recommended?

Most vitamin D experts recommend at least 1,000 IU of supplemental vitamin D daily, and 10,000 IU or more might be necessary for some people. Other experts recommend weekly dosing of 25,000-50,000 IU vitamin D3. Also, to acutely optimize the immune response, Dr. John Cannell, Executive Director of the non-profit Vitamin D Council, recommends in an article in Alternative Medicine Review up to 2,000 IU per kilogram body weight for 3-5 days.*

Thorne Takes Purity to Another Level

Some vitamins are needed only 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.
