Why Vitamin D Supplements Are NOT the Same as Sunlight

The assumption that vitamin D supplements will protect you against diseases associated with low vitamin D levels is incorrect, according to Australian researchers. The report found that vitamin D supplements are immunosuppressive and may actually make diseases worse.
Vitamin D Nuclear Receptor (VDR) influences the expression of over 1,000 genes, including those associated with diseases such as cancer and multiple sclerosis. According to the new study, supplemental vitamin D actually blocks VDR activation, which is the opposite effect to that of sunshine.
Instead of positively impacting gene expression, vitamin D supplements appear to suppress your immune system.
Vitamin D deficiency, the researchers pointed out, is likely not a cause of disease but rather is a result of the disease process. And increasing vitamin D intake may make the diseases worse.
The body regulates production of all the vitamin D it needs, the researchers said, and dysregulation of vitamin D by supplementation has been associated with many chronic diseases.
How Vitamin D Performance Testing Can Help Optimize Your Health
A robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body.
Is it any wonder then that no matter what disease or condition is investigated, vitamin D appears to play a crucial role? This is why I am so excited about the D*Action Project by GrassrootsHealth. It is showing how you can take action today on known science with a consensus of experts without waiting for institutional lethargy. It has shown how by combining the science of measurement (of vitamin D levels) with the personal choice of taking action and, the value of education about individual measures that one can truly be in charge of their own health.
In order to spread this health movement to more communities, the project needs your involvement. This was an ongoing campaign during the month of February, and will become an annual event.
To participate, simply purchase the D*Action Measurement Kit and follow the registration instructions included. (Please note that 100 percent of the proceeds from the kits go to fund the research project. I do not charge a single dime as a distributor of the test kits.)
As a participant, you agree to test your vitamin D levels twice a year during a five-year study, and share your health status to demonstrate the public health impact of this nutrient. There is a $65 fee every six months for your sponsorship of this research project, which includes a test kit to be used at home, and electronic reports on your ongoing progress. You will get a follow up email every six months reminding you "it's time for your next test and health survey."
