Jarrow Formulas® MK-7 is an extract from genetically unmodified (non-GMO) soybeans fermented with Bacillus subtilus natto. MK-7 is concentrated without solvents. MK-7 (Menaquinone-7) is an enhanced bioactive form of vitamin K2, also known as Menaquinones. MK-7 from Natto is ten times better absorbed than K1 from spinach. While vitamin K1 is primarily absorbed by the liver, MK-7 is absorbed in extrahepatic tissues, such as the arterial wall, pancreas, and testes. Vitamin K functions primarily as a co-factor for the enzyme gamma-glutamyl-carboxylase, responsible for carboxylation of specific bone proteins such as osteocalcin, and Matrix Glaprotein (MGP). MGP is a strong inhibitor of vascular calcification. Impairment of the function of osteocalcin and MGP due to incomplete carboxylation results in an increased risk for low bone density and vascular calcification, respectively.
Each softgel of MK-7 offers the amount of menaquinone-7 (MK-7) found in 120 grams of cheese.
