Vitamin D-3 is an important hormone precursor that helps support bones, immunity, and cellular health. Vitamin D-3's main function is to maintain normal levels of calcium and phosphorus in the blood which is crucial for muscles, and particularly the heart muscles to carry out their work. Scientists believe that vitamin D affects the healthy expression of over 200 genes, more than many other single compounds. Researchers and health professionals report that dificiency of vitamin D is widespread since it is not available in many foods and most people try to limit their sun exposure. Studies also suggest that vitamin D appears to interact with many different cells within the immune system and can help support the immune system’s normal function of protecting the body.
Sunlight is a 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 UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones, it helps maintain muscle strength in older adults, and it 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 manufactures in sunlight, and the form most efficient for the body's needs.
