Vitamin D3, also known as the sunshine vitamin, is a fat-soluble, naturally occurring compound made in the human body when the skin is exposed to sunlight. The vitamin is crucial for healthy growth of bones and teeth. Among the several functions it supports in the human body, the most important one is aiding in the absorption of calcium and phosphorus. These two minerals are required by the body in trace amounts to help strengthen the bones, joints, and teeth.
Vitamin D3 plays a major role in the prevention of bone diseases. A deficiency of D3 in the body can lead to rickets, a disease that can stunt growth and cause bones to soften. To maintain the overall health of your skeletal system, vitamin D3 is the order of the day.
