I’d like to share with you information regarding Vitamin D and the immune system. Most of us think that vitamin D is good for bones and is sort of placed in the category with Calcium and magnesium. But Vitamin D is much more than just a vitamin. It is known to influence over 2000 genes of the 30,000 that humans have. JoEllen Welsh, a researcher at the State University of New York at Albany has studied the effects of Vitamin D for over 25 years. Her recent research shows that vitamin D has the same effect on cancer as do cancer drugs. She is finding that cancer cells shrivel up and die when treated with potent levels of vitamin D. See the article here:
In addition, Vitamin D3 can help lower your risk of developing cardiovascular disease, breast, colon and other cancers, and autoimmune disorders like multiple sclerosis, rheumatoid arthritis, and fibromyalgia. See the article:
It is a fairly well established fact that many of us are deficient, which makes sense because we get most of our vitamin D from the sun. Milk has some vitamin D in it, but no where near the optimum levels often required. Many scientists believe that we get colds and flu in the winter not because of the change of seasons or that we’re all inside and are sharing germs, but that we lack vitamin D!!! Below is a fairly large study (n=17,000 participants) looking at vitamin D levels and cold/flu connection. Since we recommend getting enough vitamin D in our program, I thought this was relevant. If you believe you might be deficient, the prudent thing to do is to ask your physician to check your blood levels. Vitamin D is fat soluble and is stored in the body, so over time if you take too much, you can become toxic.
The current RDA is 400 mg/day, but many believe this is too low. The Department of Nutrition at the University of Harvard for example, recommends more like 1000-2000 mg. per day. I personally take 5000 mg. a day. Of course if you’re in the sun, you need no extra supplementation because your skin is the ultimate Vitamin D maker!

Yours in health!
