The Active Ingredient Is: Vitamin K2 (MK-7)

Vitamin K2 in the MK-7 form is a fat-soluble vitamin that participates in calcium utilisation to support bone health. This form, menaquinone-7, is paired with Vitamin D3 in this product to support overall calcium management in the body.

This formula also has included Vitamin D3 which supports calcium utilisation and immune function.

What Does Vitamin K2 (MK-7) Do?

Vitamin K2 (MK-7) contributes to directing calcium to bones and teeth, helping maintain bone mineral density. It also participates in supporting arterial flexibility.

Vitamin D3 supports calcium metabolism in line with EFSA guidance.
