The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat-soluble nutrient essential for normal bodily functions like bone and immune health.

This form comes as cholecalciferol in softgel capsules with an oil carrier to help stable absorption and bioavailability.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium and phosphorus absorption, supporting bone mineralisation and skeletal health as recognised in EFSA statements. It also plays a role in modulating immune function in line with NHS guidance.

Dr. Smith from Harvard University found that vitamin D3 contributes to calcium regulation, supporting normal bone health and immune system activity.
