The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for normal calcium metabolism and immune function.

This form is commonly sourced as bioavailable vitamin D3 and is paired with Vitamin K2 in this product to support calcium handling and bone health pathways.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption in the gut and supports immune function in line with NHS and EFSA context. It plays a role in maintaining normal bone structure and mineral balance.

In this formulation, Vitamin K2 MK-7 complements D3 by directing calcium to the bones, a combination discussed in the scientific context surrounding bone and cardiovascular health.

References to the synergistic action come from research led by Dr. Vermeer of Wageningen University, which highlights the interaction of D3 with K2 in bone and vascular contexts.
