Vitamin D3 (Cholecalciferol)

Vitamin D3 is a natural form of Vitamin D. It is essential for the regulation of calcium and phosphorus within the body, and plays an important role in maintaining the structure of bone and teeth, and normal immune function. The most abundant sources of Vitamin D3 are found in animal products such as oily fish and egg yolks, making it difficult for those consuming a plant-based diet to consume sufficient amounts naturally. Fortified foods such as spreads and breakfast cereals, and supplements are often required to ensure an adequate intake for this group.
