As stated by Dr. Mercola:
Vitamin D deficiency is pandemic in the United States, but many Americans, including physicians, are not aware that they may be lacking this important nutrient.
There are only 30,000 genes in your body and vitamin D has been shown to influence over 2,000 of them. That is one of the primary reasons it influences so many diseases, from cancer and autism to heart disease and rheumatoid arthritis.
A study by Dr. William Grant, Ph.D., internationally recognized research scientist and vitamin D expert, found that about 30 percent of cancer deaths -- which amounts to 2 million worldwide and 200,000 in the United States -- could be prevented each year with higher levels of vitamin D.
Vitamin D has a protective effect against cancer in several ways, including:
• Increasing the self-destruction of mutated cells (which, if allowed to replicate, could lead to cancer)
• Reducing the spread and reproduction of cancer cells
• Causing cells to become differentiated (cancer cells often lack differentiation)
• Reducing the growth of new blood vessels from pre-existing ones, which is a step in the transition of dormant tumors turning cancerous
Beyond cancer, the researchers pointed out that increasing levels of vitamin D3 could prevent diseases that claim nearly 1 million lives throughout the world each year! And other studies showed that you can decrease your risk of cancer by more than half simply by optimizing your vitamin D levels with sun exposure but it’s always not enough so you must supplement, therefore, if you take a look at www.DrinkSupplements.com you will find a product that is in liquid form, bioavailable and has 1,000IU per serving.
Vitamin D even fights colds and the flu, as it regulates the expression of genes that influence your immune system to attack and destroy bacteria and viruses. In fact, it is very rare for someone with optimized vitamin D levels to come down with the flu.
