Vitamin D is required to promote calcium absorption, which helps to maintain healthy bones and teeth. Vitamin D also supports a healthy immune system and the health of the pancreas, as well as the health of various tissues including breast and colon tissue. It may also support neuromuscular function in older adults. The natural Vitamin D3 in this product is the same form produced by the body when our skin is exposed to sunlight. As we age, our bodies produce this important nutrient less efficiently. This formulation provides premium, natural Vitamin D3 in convenient, easy to swallow vegetable capsules.*
