Additional Information

Vitamin D is a nutrient that can be readily produced by your body after being exposed to sunlight. As a vitamin found in foods, it is fat soluble and is absorbed in the jejunum of the small intestine. Some of the produced or absorbed Vitamin D is converted to an active hormone form called calciferol by the liver and kidney. This hormone actively helps maintain levels of calcium and phosphorus in the bloodstream.

Bodily Functions Performed by Vitamin D

Vitamin D’s primary function within the body is to maintain an appropriate calcium and phosphorus balance. By doing so, the bones are able to absorb minerals properly and go through continual reformation. Vitamin D also is necessary for the utilization of calcium and aids in healthy growth and development in children.

Symptoms Of Deficiency:
  • Leads to rickets
  • Contributes to tooth decay
  • Osteoporosis
  • Weak muscles
  • Fatigue
  • Pyorrhoea
  • May enhance aging
Foods High In Vitamin D

The American Dietetics Association (ADA) recommends 5-15 minutes of sun light exposure to the hands, arms and face a day. This vitamin can also be found in various fishes, soy milk and other dairy products as well as oatmeal and cereals.
