What Does Vitamin D Do in the Body - Nutrition Tutorial Series

Vitamin D Overview


Vitamin D is a hormone produced in the skin from the ultraviolet rays of the sun.
Vitamin D is commonly taken as a supplement as it is only found in small amounts in some animal foods.


Health Benefits of Vitamin D


Vitamin D is known for having many health benefits. It is known as the "sunshine vitamin".
The following is a list of the health benefits associated with Vitamin D:

  • Important for normal bone development. Children with a Vitamin D deficiency are often afflicted with rickets, which is a disease caused by defective mineralization of growing bones.
  • May protect against some forms of cancer, including colon and breast cancer, leukemia, malignant melanoma and lymphoma.
  • Helps with psoriasis, as does sunlight.
  • Helps fight against colds and flu. Tuberculosis was once treated with sunshine. Some of these patients probably had a Vitamin D deficiency.


Vitamin D Deficiency Symptoms


Inadequate intake of Vitamin D may result in Crohn's disease, celiac and non-celiac gluten sensitivity, and inflammatory bowel disease.

Other symptoms may include muscle weakness and bone pain, asthma in children, cancer, cognitive impairment in older adults. Vitamin D deficiency has also been linked to an increased risk of death from cardiovascular disease.


Foods Rich In Vitamin D


Vitamin D is found naturally in very few foods. The main source of Vitamin D is from the sun.
However, Vitamin D can be found in some fish, fish liver oils, and egg yolks.
Dairy products, such as milk and yogurt, and some grain products, such as cereals, are fortified with Vitamin D.
