The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for normal bodily functions involved in mineral metabolism and bone support.

This form is sourced from natural origins and packaged in a softgel capsule to aid stability and delivery.

What Does Vitamin D3 Do?

Vitamin D3 helps with normal calcium absorption and supports bone mineralisation, a function recognised in EFSA guidance. It also helps with supporting immune system regulation and cardiovascular health in line with scientific assessments.

Dr. Autier from a European university found evidence backing these roles, reflecting Vitamin D3’s involvement in these physiological processes.
