The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for maintaining normal bone and teeth health and supporting immune function.

This form is cholecalciferol supplied in olive oil to aid absorption from the gut.

What Does Vitamin D3 Do?

Vitamin D3 helps maintain normal bone health and supports immune function, in line with EFSA and NHS guidance.

Dr. Manson of Harvard University found that daily Vitamin D3 improves serum vitamin D status, underpinning its role in supporting these normal bodily processes.
