Source Naturals Vitamin D-3 provides the optimal form of vitamin D, cholecalciferol. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body's needs. Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to sunlight. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones; it supports muscular strength; and it also plays an active role in a healthy immune response.
