Studies Now Show Vitamin D3 Reduces Many Cancers, Heart Disease, Improves Fertility, Diabetes, Weight Control, Memory

Up to 75 Percent of Americans are Deficient in Vitamin D. I feel strongly that the limits based on bone strength is much too low and most should try to attain the higher limits if not beyond what is recommended now.

When I learned just a few years ago that noon sunlight produces 22,000 International Units of vitamin D3 in just 15 minutes for Caucasians, I concluded immediately that vitamin D must serve purposes other than just give us good bones. Think Evolutionary forces. But I found relatively few studies in the USA except at Oregon State University, Australia, and Sweden. The latter two had research indicating that sunscreens may have inadvertently contributed to a sharp surge in melanoma by not screening UVA, the penetrating part of the sun rays but did a good job in stopping UVB, the burning rays. The Oregon State researchers made the alarming guess that the sharp increase in Autism in Oregon, the highest in the nation, may be due to a sharp drop in vitamin D provided to mothers and babies due to sharp increase in sunscreen use, high latitudes, and rainy states.

Vitamin D provides an important contribution during brain growth and probably synaptic connections of neurons during the early life of babies first years. Now over 2,000 studies have been reported just in 2009.

I have found that increasing my dose to 2500 units daily has greatly reduced my skin autoimmune disease as it has for psoriasis where it has long been known that sunlight helps ameliorate psoriasis, an autoimmune disease.

Some doctors are massively increasing the dose of vitamin D to their deficient patients of up to 30,000 units each day and 50,000 once a month to prevent deficiencies. One woman I know has sharply decreased or eliminated the frequent colds she use to get.

Doctors who are very conservative for good reasons, but are not as versed in scientific studies so as President Obama said several months ago, it takes 17 years for published Best Practices to be implemented by 50 percent of the doctors and hospitals. That is why he wants to have a panel of experts make recommendations which are not mandatory, but should be much more coercive.

Many Studies Now Show Vitamin D Reduces Cancers, Heart Disease, Improves Fertility, Weight Control, and Memory Aug 1, 2009, Shari Roan Vitamin supplements have been both heralded and hyped over the years, only to ultimately fall from grace once research proves them to be little more than placebos in our quest for longer life or better health. But at least one substance may have true merit -- vitamin D.

Long considered just a supplement consumed with calcium for bone health, this humble vitamin may have untapped potential in fighting or preventing disease, suggests an explosion of new research. Not only has it shown promise in reducing the risk of, among other things, diabetes, pancreatic cancer, breast cancer and cardiovascular disease, but it also seems to improve infertility, weight control and memory. ...

Five studies on colorectal cancer and breast cancer, taken together, showed that people with levels higher than 34 to 52 ng/mL had a 50% reduced cancer risk, says Cindy D. Davis, a researcher at the National Cancer Institute's Nutritional Science Research Group. ...,0,4706112.story?track=rss
