Vitamin D

Vitamin D is a fat-soluble vitamin. Fat-soluble vitamins are stored in the body's fatty tissue. Vitamin D helps the body absorb calcium. Calcium and phosphate are two minerals that are essential for normal bone formation. Throughout childhood, your body uses these minerals to produce bones. If you do not get enough calcium, or if your body does not absorb enough calcium from your diet, bone production and bone tissues may suffer. Vitamin D deficiency can lead to osteoporosis in adults or rickets in children.
