Does Vitamin D Deficiency Cause Symptoms?

Yes, deficiency of vitamin D can cause bone pain and muscle weakness. However, mild vitamin D deficiency is not necessarily associated with any symptoms. Vitamin D has been referred to as the "sunlight vitamin" because it is made in our skin when we are exposed to sunlight. It can also be obtained through dietary sources, but the main source of vitamin D in our diet is foods that have been fortified to include the vitamin (such as in milk and other dairy products). Vitamin D is only found naturally in significant levels in a few foods, including fatty fish, cod-liver oil, and eggs.
