The Vitamin D Cure

In response to a flood of questions about what vitamin D products to take we have created this helpful guide.

Jerome Burne, at the Daily Mail in London, England, asks the question in his January 15th story on vitamin D and Dr. Dowd's new book, The Vitamin D Cure.

For starters, vitamin D is not a vitamin; it is a hormone from the same family of steroid hormones as estrogen, progesterone, testosterone, and cortisol. This means that, like these other hormones, vitamin D regulates gene expression in the nucleus of a cell. It doesn’t just have a seat on the front row in regulating our biochemistry, it is conducting the orchestra!

Ninety percent of our vitamin D comes from sun exposure. In some cultures they do get closer to half their vitamin D from food. These cultures consume large amounts of fish, particularly Salmon, Tuna, Mackerel, Sardines, seal and seal blubber and Herring. Examples of these people are Icelanders, Finnish, Dutch, Norwegians, Japanese, Okinawans, and Inuit Indians (Eskimos).
