The Active Ingredient Is: Vitamin D3 (Cholecalciferol)
Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for supporting bone and immune health.
This form is delivered as cholecalciferol in tablet form and supports the body's normal handling of calcium and phosphorus to aid in bone mineralisation.
What Does Vitamin D3 Do?
Vitamin D3 helps regulate calcium absorption, supporting normal bones and immune function. It is involved in maintaining serum calcium levels and normal muscle function, in line with NHS and EFSA guidance cited in scientific volumes.
Dr. Smith of Harvard University found that this nutrient plays a role in supporting immune health and skeletal maintenance through its action on calcium and phosphorus metabolism.
