Vitamin D is a fat-soluble vitamin. It belongs to compounds, including vitamins D1, D2, and D3.
The human body is capable of producing vitamin D naturally. This happens when it is directly exposed to light from the sun. Vitamin D can also be obtained from certain foods and supplements to ensure its adequacy in your blood.
Vitamin D has a wide range of essential functions. The most vital include regulating the absorption of phosphorus and calcium and enhancing the immune system’s role (1).
Here’s the thing — getting adequate vitamin D is vital for the growth and development of your teeth and bones, as well as improved resistance to specific diseases.
This article discusses the benefits of vitamin D, information about its downsides, and how much of it you need.
It helps in disease-fighting
Apart from its primary benefits, studies suggest that vitamin D may also be involved in:
· Minimizing the risk of multiple sclerosis. A review of population-based studies conducted in 2018 found that low vitamin D levels are associated with a high risk of multiple sclerosis (2).
· It decreases the risk of heart disease. Vitamin D deficiency has been linked to a risk of heart diseases, including stroke, heart failure, and hypertension. However, it is unclear whether vitamin D deficiency contributes to heart disease or is simply an indication of poor health when you have a chronic ailment (3).
· Vitamin D reduces the likelihood of severe ailments. Although the studies are mixed, it is essential to note that vitamin D may decrease the severity of flu and make COVID-19 infections less likely. In addition, according to a recent review, low vitamin D levels play a role in acute respiratory distress syndrome (4, 5).
· Supports immune health. People who do not have adequate vitamin D levels may have a high risk of infections and autoimmune conditions, such as type 1 diabetes, rheumatoid arthritis, and inflammatory bowel disease (6).
