Vitamin D is one of the essential nutrients that our body requires. Lack of adequate vitamin D in the body can lead to several health problems. The vitamin can help strengthen bones, reduce the risk of heart disease, rheumatoid arthritis and multiple sclerosis.
Some studies have also pointed out that the deficiency of Vitamin D increases can increase the risk of developing dementia. It also plays a major role in managing respiratory tract infections and autoimmune diseases among others  .
It is a fat-soluble vitamin that our body can make from sunlight or can be ingested via food or supplements. A very small amount comes from a few foods you eat, such as some fish, fish liver oils, egg yolks and fortified dairy, cereals and grain products.
Vitamin D deficiency symptoms can appear in the form of any disease involving heart, bones and many organs. A simple blood test can determine whether or not you have a vitamin D deficiency. Your doctor can advise if you need to take a vitamin D supplement. There is no consensus on vitamin D levels required for optimal health, and it differs depending on age and health conditions. Compared to women, vitamin D deficiency is increasingly reported in men  .
The deficiency of vitamin D can lead to rickets in children and osteomalacia in adults. This occurs when a bone tissue does not properly mineralize, leading to soft bones and skeletal deformities. It is estimated that around one billion people worldwide have a vitamin D deficiency, according to the Harvard School of Public Health  .
Researchers have also established associations between low vitamin D levels and prostate cancer. It was also found that men with erectile dysfunction were found to have low levels of vitamin D. People with low vitamin D levels were also found to be diagnosed with schizophrenia when compared to those who had a sufficient amount of vitamin D in their body, as noted by a study  .
