Vitamin DVitamin D is well-known for its role in the regulation of calcium balance and bone health. Within the last ten years, an enormous amount of research has focused on additional benefits. Observational studies report that low vitamin D levels may increase the risk of TB, HIV, Hepatitis C, respiratory tract, and other infections.

The vast majority of human cells have vitamin D receptors. It is particularly essential for optimal immune system function. Vitamin D stimulates cells that fight against bacterial, fungal, and viral infections while creating an inhospitable environment for microbial growth.

Not only does vitamin D support a healthy immune system, it helps control an overactive immune response by suppressing cells that cause excessive inflammation. If you suffer from multiple infections or inflammatory symptoms, checking your vitamin D level might be just what the doctor ordered.
