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.
- 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.
- 250 mg of 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.
