Washington: Researchers from Boston University School of Medicine (BUSM) have shown that improving vitamin D status by increasing its level in the blood could have a number of non-skeletal health benefits.

The study revealed for the first time that improvement in the vitamin D status of healthy adults significantly impacts genes involved with a number of biologic pathways associated with cancer, cardiovascular disease (CVD), infectious diseases and autoimmune diseases.

While previous studies have shown that vitamin D deficiency is associated with an increased risk for the aforementioned diseases, these results go a step further and provide direct evidence that improvement in vitamin D status plays a large role in improving immunity and lowering the risk for many diseases.

Vitamin D is unique in that it can be both ingested and synthesized by the body with sun exposure.

It is then converted by both the liver and kidneys to a form that the body can use.

An individual`s level of vitamin D, or their vitamin D status, is determined by measuring the level of 25-hydroxyvitamin D in the blood.

Vitamin D deficiency, which is defined as a status of less than 20 nanograms per milliliter (ng/mL) of 25-hydroxyvitamin D, can cause a number of health issues, including rickets and other musculoskeletal diseases.

Recently, however, data suggests that vitamin D deficiency (
