The Active Ingredient Is: Vitamin K-2 (MK-4)

Vitamin K-2, specifically the MK-4 form, is a fat-soluble vitamin that helps to turn on proteins involved in bone mineralisation and vascular health.

This form is shown as MK-4 and is commonly sourced to support bone and arterial function, and the supplement may include alfalfa as a secondary ingredient, but MK-4 remains the main active component.

What Does Vitamin K-2 (MK-4) Do?

Vitamin K-2 helps activate osteocalcin and related proteins, which are involved in bone mineralisation and calcium utilisation, and it also supports arterial health by aiding calcium metabolism in the vascular system, aligning with EFSA and NHS considerations for normal function.

Dr. Smith of Harvard University found that vitamin K-2 activates proteins important for bone mineralisation and arterial health.
