The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for everyday bodily function linked to bone support and immune health.

This form is commonly derived from suitable sources and is widely used to support your body's normal calcium handling and mineralisation processes.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and supports bone mineralisation, with extra roles in immune function in line with EFSA guidance.

Scientific research suggests that Vitamin D3 and Vitamin K2 team up to optimise calcium use for bones and arterial health, with the combination boosting bone strength and cardiovascular support as described by experts at Maastricht University.

This formula also includes Vitamin K2, which helps direct calcium to bones and away from arteries, supporting your body's normal calcium utilisation.

Dr. Knapen of Maastricht University found that Vitamin K2 activates proteins involved in calcium metabolism, underpinning the synergy between D3 and K2 for bone and vascular health.
