The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for bone and immune health. This form is derived from lanolin and is used by the body to support calcium metabolism and immune function.

The Primary Benefit Is: Vitamin D3 Support

Vitamin D3 helps regulate calcium absorption, supporting normal bone structure and immune system function in line with NHS and EFSA guidance. This form is converted by the body into an active hormone that aids mineral balance. Dr. Gallagher of the University of Leicester found that supplementation can improve serum vitamin D levels and bone mineral density.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, maintaining strong bones and supporting immune function. It is a fat-soluble nutrient that contributes to normal mineral balance in the body.
