Research has identified how vitamin D3 and periodontitis influence Type 2 diabetes. They found increased odds of developing Type 2 diabetes among people with gum disease who are also lacking in vitamin D3.

The study, published in BMJ Open Diabetes Research and Care. Participants were over the age of 30, and health interviews and physical measurements were conducted in-home and at a mobile examination centre.

They know that vitamin D is not only helpful for bone health but is also shown to have antimicrobial and anti-inflammatory effects. Sufficient vitamin D levels can potentially decrease inflammation and affect oral microbes related to gum disease.

The prevalence of pre-diabetes and Type 2 diabetes is rising, but the role of gum disease in the origin of the disease is still unclear. According to Zuk, it's critical to explore the impact of novel risk factors associated with disease risk.


Vitamin D is predominantly produced in the skin from sun exposure or through the consumption of some foods. Gum disease is caused by an excess and persistence of gum inflammation that result from oral microbes. At its worst, poorly controlled diabetes worsens periodontal disease.

Researchers have found that half of the American adults have some form of gum disease and lack vitamin D sufficiency.  The author hopes that by better understanding exposures, a targeted treatment can be an additional line of defense against diabetes.

Because it's the first study, they really need to look at these two exposures again in other studies and population. It might impact further diabetes research.
