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

The Active Ingredient Is: Vitamin K2, or menaquinone-7, is a fat-soluble nutrient essential for directing calcium to where it is needed for bone mineralisation and away from tissues where it is not required. This form is derived from natto, a fermented soybean product, and is used to support normal physiological processes related to calcium handling.

This formulation uses menaquinone-7 sourced from natto and is presented as a high-strength vitamin K2 supplement. The primary role of this ingredient is to participate in activating proteins that regulate calcium distribution in the body.

What Does Vitamin K2 Do?

Vitamin K2 helps activate osteocalcin and matrix Gla-protein, which are involved in bone mineralisation and the regulation of calcium deposition in the body. It supports normal bone health and contributes to maintaining arterial elasticity as part of normal physiology.

The activation of these proteins by Vitamin K2 aligns with EFSA-endorsed nutrient functions and general nutritional guidance for healthy bones and cardiovascular support.
