Vitamin K2 is necessary for the synthesis of osteocalcin, the protein in bone tissue upon which calcium crystallizes. Vitamin K2 helps move calcium out of the arteries and into the bones where it belongs.
Vitamin K2 consists of 10 different vitamin subtypes (menaquinones) that are designated as MK-4 through MK-14. Small amounts of MK-4 can be consumed from meat and cheese as well as synthesized from vitamin K1 by intestinal bacteria; MK-7 is found in natto, a fermented soy food. Because good dietary sources of K2 are limited, and because conversion of K1 to K2 in the intestine can be insufficient, poor vitamin K2 status is common.
Activated K2 contains:
- 75 mcg of Mixed Menaquinones with predominately MK-7, which is thought to be the best supplemental form of vitamin K2 by having unique effects on vascular and bone biology.
- GLA Activation Complex consisting of choline and glutamic acid.
- Choline supports liver health and function where most vitamin K activity and metabolism occurs.
- Glutamic acid provides additional substrate for the activities of K2 and the enzyme gamma-glutamyl-carboxylase, to aid in the full activation of vitamin K-dependent proteins.
