Vitamin D: the alternative hypothesis. Albert PJ, Proal AD, Marshall TG. Autoimmun Rev. 2009 Jul;8(8):639-44. Epub 2009 Feb 12. Review. PMID: 19393200 Emerging molecular evidence suggests that symptomatic improvements among those administered vitamin D is the result of 25-D's ability to temper bacterial-induced inflammation by slowing VDR activity. While this results in short-term palliation, persistent pathogens that may influence disease progression, proliferate over the long-term.

It seems not a single day passes that I don't learn something new about this unique hormone (mis)named "vitamin D." \nFrom its humble beginnings recognized only as the factor responsible for bone maturation (with deficiency leading to childhood rickets), vitamin D now commands a recognized role in almost every conceivable aspect of health and disease. \n

"Friday Oct 16, 2009 (foodconsumer.org) -- Results of a new trial presented at an international research conference in Bruges suggest that vitamin D supplementation can reduce the risk of premature births and boost the health of newborn babies, the Times reported Oct 10. Vitamin D deficiency, which is common everywhere, has been linked in many previous studies to a variety of illnesses from heart disease, cancers, multiple sclerosis and many others. In the trial, Dr. Bruce Hollis and Dr. Carol Wagner of the Medical University of South Carolina, Charleston, gave one group of pregnant women 4,000 IUs per day of vitamin D at about three months of pregnancy. They gave a second group 400 IUs per day, amounts recommended by U.S. and UK"

Reducing the Burden of Disease Through Adequate Intake of Vitamin D3. A presentation at University of California, San Diego, April 9, 2008 by William B. Grant, Ph.D

"(NaturalNews) People still don't get it: Vitamin D is the "miracle nutrient" that activates your immune system to defend you against invading microorganisms -- including seasonal flu and swine flu. Two months ago, an important study was published by researchers at Oregon State University. This study reveals something startling: Vitamin D is so crucial to the functioning of your immune system that the ability of vitamin D to boost immune function and destroy invading microorganisms has been conserved in the genome for over 60 million years of evolution. As this press release from Oregon State University (http://www.eurekalert.org/pub_relea...) explains: The fact that this vitamin-D mediated immune response has been retained through millions of years of evolutionary selection, and is still found in species ranging from squirrel monkeys to baboons and humans, suggests that it must be critical to their survival, researchers say. "The existence and importance of this part of our immune response makes it clear that humans and other primates need to maintain sufficient levels of vitamin D," said Adrian Gombart, an associate professor of biochemistry and a principal investigator with the Linus Pauling Institute at Oregon State University."

"For more than 80 years, scientists have known that vitamin D is important for building bones. And for most of those 80 years, people thought this was the only thing it was good for. In the past decade, however, we've learned two important things about vitamin D: it appears to have many other important health effects, and many Americans don't get enough of it. In 2008, new research pointed to a vitamin D deficiency as a possible contributing factor in heart disease. And the suspected link between vitamin D deficiency and cancer grew even stronger. This surely will spur much new research in 2009. Why is vitamin D deficiency so common? The vitamin is made in our skin when sunlight strikes it. Many Americans-especially those who live in the northern part of the country, are elderly or have dark skin-don't soak up enough sun. And the vitamin isn't found in many foods. The main sources are fatty fish (such as salmon, mackerel, herring and sardines) and milk, cereal and juices that have been fortified with it. Vitamin D deficiency often is unsuspected because it causes no direct symptoms; like high blood pressure, it does its damage silently."
