Jarrow Formulas NattoMax 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.

Each softgel of MK-7 offers the amount of menaquinone-7 (MK-7) found in 120 grams of cheese. (LEF has more K2 in its Vitamin K formula, but no nattokinase.)
