The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or simply cholecalciferol, is a fat-soluble vitamin that’s key for healthy bones and immune function.

This form is cholecalciferol and is the go-to form for lifting and keeping serum vitamin D levels steady, helping bone health and overall vitality.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium and phosphate balance, supporting bone mineralisation and normal muscle function.

It also modulates immune responses, helping the immune system function in line with NHS and EFSA guidance. Dr Holick of Harvard University described vitamin D3 as the go-to form for increasing serum levels, supporting its role in these physiological processes.
