Vitamin D is required to promote calcium absorption, which helps to maintain healthy bones and teeth. Vitamin D also supports a healthy immune system, the health of the pancreas and supports 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 offers advanced Vitamin D3 support in oil based Softgels to promote optimal absorption and assimilation.
