The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for supporting normal calcium use in the body.

This formula also contains Vitamin K2 MK-7, which helps to direct calcium to the bones and supports overall mineral utilisation.

What Does Vitamin D3 Do?

Vitamin D3 contributes to the normal absorption of calcium and supports bone and muscle health, in line with NHS and EFSA guidance. This benefit is supported by research indicating improved calcium management with adequate D3 status.

Dr. Holick of Harvard University has highlighted Vitamin D3's role in regulating calcium uptake and utilisation to support skeletal health.
