What happens when someone suffers from vitamin D deficiency?

Vitamin D has fat soluble compounds known as calciferols. Vitamin D is not a true vitamin because it can be absorbed by your skin when cholosteral reacts with ultraviolet light from the sun. Sunscreens and clothes can block UV sunlight rays from reaching the skin and would cause vitamin D deficiency. To help prevent this possibilty, foods or drinks like milk or vitamin water would work very well with Vitamin D2 and D3. However, a very severe deficiency of vitamin D can lead to softening of bones called the osteomalacia in adults and rickets in teens and children.
