1. Supports Bone Health: Vitamin D3 and K2 work together to promote the absorption of calcium and maintain healthy bones, reducing the risk of osteoporosis and fractures.
2. Boosts Immune System: Vitamin D3 is known as the "sunshine vitamin" and is crucial for a strong immune system. The addition of K2 helps to activate certain immune cells, further enhancing immune function.

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3 is a fat-soluble vitamin essential for normal skeletal health and immune function.

This product pairs Vitamin D3 with Vitamin K2 cofactors to optimise calcium utilisation and support healthy mineral balance in the body.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption in the gut, supporting skeletal strength. It also supports immune function in line with UK and EU health recommendations.

In this formula, Vitamin K2 acts as a cofactor to direct calcium into bones and away from soft tissues, while Vitamin D3 enhances calcium availability; studies indicate that combining these nutrients may have added benefits for bone and vascular health.

Dr. Zhang of the University of Exeter found that combined supplementation may have a greater effect than either nutrient alone.

This combination supports calcium handling and mineralisation processes essential to healthy bones and a resilient vascular system.
