The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for bone and immune health.

This form is commonly used in supplements to support normal calcium metabolism and overall nutritional wellbeing.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, contributing to normal bone health and immune function in line with NHS and EFSA guidance.

Dr. Schwalfenberg of the University of Alberta found that vitamin D3 and vitamin K2 together may synergistically support bone density and arterial elasticity.
