The Active Ingredient Is: Vitamin K2 MK-4 (Menaquinone-4)

Vitamin K2 MK-4 is a fat-soluble vitamin essential for calcium utilisation in the body. This synthetic vegetarian form is chemically identical to naturally occurring menaquinone-4 and is designed to support bone and connective tissue function.

This form is vegetarian and synthetic, with minimal inactive ingredients, formulated to be hypoallergenic and suitable for vegan diets.

What Does Vitamin K2 MK-4 Do?

Vitamin K2 MK-4 activates matrix Gla-proteins and osteocalcin, which direct calcium away from soft tissues and into the bone matrix to support skeletal structure. The MK-4 form also has potential effects on cartilage health and joint flexibility through connective tissue maintenance.

In addition, this MK-4 form is capable of crossing the blood-brain barrier, suggesting broader biological reach in supporting normal physiological processes.

This product is not intended to diagnose, treat, cure, or prevent any disease.
