However, the main question posed is whether healthy people would benefit from vitamin D supplements and a resounding yes is the answer to this question. As far as the results of a research conducted at Boston University School of Medicine go, increased levels of vitamin D in blood can have numerous health benefits. In the study findings which were published on the Internet in PLOS ONE, it was revealed that increased status of vitamin D in healthy adults can have a significant impact in their genes especially those associated with cardiovascular disease, autoimmune disease, infectious diseases and even cancer.

Vitamin D helps prevent diseases

Even though past studies have shown that a deficiency in vitamin D can increase the risk of one suffering from these diseases, this new study was the first one to provide a direct evidence showing that improving the status of vitamin D in the body plays a crucial role in boosting immunity as well as minimizing the risk of diseases, most of which can be potentially deadly.

Exposure to sun helps the body to synthesize vitamin D, which can also be taken orally. A blood test is used for measuring vitamin D level in the body and it shows 25- hydroxyvitamin D level in the blood. Lack of enough amount of vitamin D in the blood is usually defined as when the level of this vitamin is no more than 20 nanograms in every milliliter. For a long time now, it has been known as one of the leading causes of many health problems like musculoskeletal diseases like rickets. However, as previously reported by Natural News, scientists have now found that a link exists between deficiency of vitamin D and other serious illnesses, including breast cancer, rheumatoid arthritis and MS.

How the research was conducted

In this study, a double blind, randomized trial was conducted by the researchers which involved eight health women and men aged 27 years in average. All the subjects used in the research had a deficiency of vitamin D or the level was insufficient when the trial was starting. Three participants in the study took 400 IU of vitamin D every day while five of them were given 2000 IU per day for a period of two months. The researchers conducted white blood cell samples when the trial was starting and at the end as well. Researchers also conducted a broad analysis of gene expression. According to the investigations of the analysis, it was found that having enough levels of D vitamins had a significant effect on the gene’s activity. Such alterations could be crucial in enhancing prevention of autoimmune diseases, cancer, cardiovascular disease and infectious diseases.
