Vitamin D3 is a fat-soluble vitamin essential for healthy bones and immune system function. This form is the everyday cholecalciferol supplement and is often paired with minerals to help metabolism work better and absorption. Vitamin D3 helps regulate calcium absorption, supporting healthy bones and teeth, and also helps immune function in line with NHS and EFSA guidance. Dr. Martineau from the University of Oxford found that Vitamin D3 supplementation is linked to lower risk of acute respiratory infections, reflecting its immune support role.
