How Vitamin D Reduces Inflammation

Posted by on

As we move through the winter months, we encourage all of our XYW Members to boost their intake of vitamin D. Beyond the immune system boosting and mood improving benefits during this time of year, vitamin D inhibits inflammation. As we discussed in our Reducing Inflammation: How? Why? blog, reducing inflammation boosts your ability to combat disease.*

An article that was published today in Science Daily which describes how researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. Their findings are published in this month's The Journal of Immunology.

According to the lead author, Dr. Elena Goleva, their study "goes beyond previous associations of vitamin D with various health outcomes. It outlines a clear chain of cellular events, from the binding of DNA, through a specific signaling pathway, to the reduction of proteins known to trigger inflammation. Patients with chronic inflammatory diseases, such as asthma, arthritis and prostate cancer, who are vitamin D deficient, may benefit from vitamin D supplementation to get their serum vitamin D levels above 30 nanograms/milliliter."

Quoting from the Science Daily article:

In the current study researchers examined the specific mechanisms by which vitamin D might act on immune and inflammatory pathways. They incubated human white blood cells with varying levels of vitamin D, then exposed them to lipopolysaccharide (LPS), a molecule associated with bacterial cell walls that is known to promote intense inflammatory responses.

Cells incubated with no vitamin D and in solution containing 15 ng/ml of vitamin D produced high levels of cytokines IL-6 and TNF-alpha, major actors in the inflammatory response. Cells incubated in 30 ng/ml vitamin D and above showed significantly reduced response to the LPS. The highest levels of inflammatory inhibition occurred at 50 ng/ml.

Through a complex series of experiments, the researchers identified a new location where the vitamin-D receptor appears to bind directly to DNA and activate a gene known as MKP-1. MKP-1 interferes with the inflammatory cascade triggered by LPS, which includes a molecule known as p38, and results in higher levels of IL-6 and TNF-alpha.

The takeaway according to Dr. Goleva is that "this newly identified DNA-binding site for the vitamin-D receptor, and the specific pathways inhibited by higher levels of vitamin D provide a plausible mechanism for many of the benefits that have been associated with vitamin D. The fact that we showed a dose-dependent and varying response to levels commonly found in humans also adds weight to the argument for vitamin D's role in immune and inflammatory conditions."

In layman's terms, let's make sure that we are getting sufficient vitamin D into our system each and every day. XY Wellness offers 2 high-quality options for you to consider:

  • Vitamin D Synergyis designed to meet the unique daily needs of men faced with prostate concerns, and contains 2,000 IU of vitamin D3 plus with 200 mcg of vitamin K.* 
  • OmegAvail Ultrawhich contains 1,000 IU of vitamin D3 plus 525 mcg of vitamin K.*

Both are great choices. If you have any questions regarding your serum vitamin D level, do not hesitate to contact Dr. Geo. We are are here to help you.
