Your skin makes vitamin D when it's exposed to sunlight, and it is also in fortified foods and supplements. While vitamin D plays a number of roles, its main function is to sustain normal levels of calcium and phosphorus in the blood to maintain the hardening of the bones, cell operations and correct nerve and muscle function.
Vitamin D and Calcium Levels
Vitamin D helps the body sustain the correct levels of calcium and phosphorus. This helps keep bones, teeth and nails strong. The vitamin can help adults avoid osteoporosis, and it can prevent rickets in children. It can help fight prostate cancer, depression, high blood pressure, breast cancer and heart disease, notes MayoClinic.com. It may also play a role in preventing obesity, diabetes and sclerosis.
Cancer Prevention
The vitamin may help fight several types of cancer, including prostate, lung, breast, kidney and uterine cancer, according to Laboratory Scientist Dennis Mangan. Vitamin D in sufficient amounts can help normalize the growth of cells, which prevents them from becoming cancerous. Studies show individuals who had a considerable amount of vitamin D in their blood had a decreased risk of getting cancer, notes Physorg.com.
Immune System Support
Vitamin D may help fight against diabetes, multiple sclerosis and rheumatoid arthritis because it decreases irritation and strengthens the immune system. The vitamin has been connected to more than 200 genes, including those of the autoimmune system, according to Physorg.com. If taken during pregnancy, vitamin D may reduce the chances the newborn develops a disease later in life, notes Physorg.com. Therefore, the vitamin is essential for a overall growth and development.
Supporting Skin Health
Vitamin D also plays a role in skin disorders, such as skin disease or psoriasis, according to MayoClinic.com. For psoriasis treatment, vitamin D is generally used topically.
