Food sources that are plentiful in vitamin D are less and rare for a great many people, in spite of certain food varieties being strengthened with vitamin D. Supplementation of vitamin D is subsequently fundamental for certain individuals.

Fortunately Vitamin D, otherwise called “the daylight nutrient,” is normally created by our bodies when presented to the sun’s UVB (Bright B) beams. Nutrient D2 is made by plants and organisms, while people and different creatures produce D3.

Vitamin D and Disease Prevention

Vitamin D is considered crucial for its important function in aiding the absorption and retention of Calcium and Phosphorus in our bodies, which are vital minerals for bone formation. Recent studies have revealed that the advantages of vitamin D extend beyond just bone health. Here are a few significant roles of vitamin D in preventing diseases.

1. Vitamin D for Better Cognitive Function

 A study utilizing Mendelian randomization on approximately 427,000 white Europeans revealed a 54% increased risk of dementia among individuals with lower levels of vitamin D in their blood, in contrast to those with adequate vitamin D levels.

2. Vitamin D for Colon Cancer

Approximately three decades ago, scientists uncovered a fascinating connection between colon cancer and geographical location. It was noted that individuals residing in regions with higher altitudes, like the northern United States, exhibited increased mortality rates from colon cancer compared to those living nearer to the equator. This finding prompted the theory that decreased levels of vitamin D could potentially contribute to the development of colon cancer.

The Journal of the National Cancer Institute published a new joint study by the American Cancer Society and other international research organizations looking at the relationship between vitamin D and colorectal cancer. Findings from the study show that higher blood levels of vitamin D are associated with a low risk of developing colorectal cancer.

Besides, other animal and laboratory studies show that Vitamin D inhibits the development and growth of breast, prostate, brain and ovary tumors.

3. Vitamin D for Cardiovascular Health

Cardiovascular diseases are currently the leading cause of death globally, with over 32% of deaths (17.9 million) annually caused by heart disease complications. Past research has shown that certain health conditions, family history, age, diet and lifestyle could all contribute to the risk of developing heart disease.

Recent results from a study in Australia that appeared in the European Heart Journal found compelling evidence that vitamin D deficiency could lead to high blood pressure and the risk of developing cardiovascular disease.

The heart is made of large muscles, and similar to skeletal muscle, the heart has vitamin D receptors. Furthermore, vitamin D helps regulate high blood pressure, impacting cardiovascular health.

One of the crucial roles that vitamin D plays in the body is boosting our immunity. Our body’s immunity is the first defense against disease-causing pathogens, and anything that can help support our immune system should be highly regarded. Vitamin D plays an important role by supporting the optimum function of dendritic, T and B cells.

Insufficient levels of vitamin D can elevate the susceptibility of individuals to infections like seasonal flu and respiratory diseases. Moreover, inadequate vitamin D levels have been associated with autoimmune conditions such as rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease.
