The Truth About Vitamin D

The Truth About Vitamin D

vit dIt’s called the sunshine vitamin because it’s produced in the skin in response to sunlight, but most of us in the Midwest simply do not get enough of it.  In fact, an estimated one billion people worldwide have Vitamin D deficiency or insufficiency. This deficiency can have significant health consequences.  Every tissue in the body has vitamin D receptors, including the brain, heart, muscles and immune system, which means Vitamin D is needed at every level for the body to function properly.

One of the most important functions of Vitamin D in the body is good bone health, in that it regulates the absorption of the minerals calcium and phosphorous.  Without adequate Vitamin D levels, we are at risk of developing bone abnormalities such as Osteoporosis, which causes our bones to become fragile, as well as Osteomalacia which causes our bones become soft.

New evidence has shown that certain receptors in your brain need Vitamin D to keep hunger and cravings under control, as well as to pump up levels of the mood-elevating chemical serotonin.  It is thought that the hypothalamus (the very small part of your brain that regulates hormonal functions, amongst other things) senses low Vitamin D levels and responds by increasing the body weight set point as well as the release of hunger-stimulating hormones. At the cellular level, Vitamin D may also prevent the growth and maturation of fat cells.

In addition to its primary benefits, research suggests that vitamin D may also play a role in:

Vitamin D may also affect our likelihood of developing different kinds of cancer.  70% of women with breast cancer are Vitamin D deficient.  Vitamin D has been shown to prevent breast cancer cell growth and decrease the expression of cancer causing genes.  JoEllen Welsh, a researcher with the State University of New York at Albany, has studied the effects of Vitamin D for 25 years.  She believes Vitamin D may be just as powerful as the most modern anti-cancer drugs.  She states, “What happens is that Vitamin D enters the cells and triggers the cell death process.  It’s similar to what we see when we treat cells with Tamoxifen, a drug used to treat breast cancer.”

In 1980 epidemiologists reported that low Vitamin D levels were associated with a greater risk of developing colorectal cancer.  Since then, researchers from around the world have linked low Vitamin D levels to a higher risk of ovarian, kidney, pancreatic and aggressive prostate cancer.

Vitamin D deficiency may also have an impact on depression.  According to new findings in the Mayo Clinic Proceedings, “add depression to the spectrum of medical illnesses associated with low vitamin D, and people with depression probably should consider a blood test to see if their vitamin D is low and whether supplements may be needed,” says researcher E. Sherwood Brown, MD, PhD, a professor of psychiatry at the University of Texas Southwestern Medical Center in Dallas. The new study is among the largest to date and shows that the two may indeed be linked.

Do you know your Vitamin D level?  Fortunately, you can get a simple blood test to determine your Vitamin D level. You can then work with your doctor or Olivera Weight Loss to coordinate the needed supplementation to optimize Vitamin D for you and your health. We carry the Metagenics brand of Vitamin D supplements in various strengths that we tailor to your needs based on your Vitamin D level.  Come ask us about them!
