The Core Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also called cholecalciferol, is a fat-soluble vitamin essential for bone wellbeing and immune function.

This form is a natural analogue of the nutrient found in animal sources and supports normal processes involved in calcium balance and skeletal maintenance.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, supporting normal bone and teeth health. It also contributes to the normal function of the immune system, as recognised in EFSA guidance.

Dr. Johnson of University of Oxford found that vitamin D3 supports immune function and calcium metabolism.
