Vitamin D is not considered a true vitamin, but a steroid hormone, due to its ability to be synthesized in the skin. It can be acquired through adequate exposure to sunlight, and through some foods and supplements. Vitamin D deficiency can cause osteoporosis and also cause rickets in children.
Function
Adequate vitamin D intake is important for the absorption of calcium required for strong bones and other needs of the body. Vitamin D also helps in the reduction of inflammation.
Side Effects
If you consume to much vitamin D it can cause the intestines to absorb to much calcium. This can cause high levels of calcium in the blood which can lead to a build up of calcium deposits in the heart and lungs. Kidney stones, vomiting, and muscle weakness can also be caused by too much vitamin D.
