Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies produce vitamin D-3 when our skin is exposed to UV rays from sunlight, but the ability to do so decreases as we age.

Vitamin D-3 maintains healthy levels of calcium and phosphorus in the body for strong bones; increases muscle strength in the elderly; and also plays an active role in a healthy immune response

. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body produces in sunlight and the most efficient form for the body's needs.
