MK-7 ( Vitamin K2 ), Jarrow Formulas, 90 mcg, 30 Softgels • Vitamin K2 as MK-7 90 mcg • Natto K2 Natto Extract • Bone and Cardiovascular Health • Dietary Supplement 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. Keep out of reach of children. Usage: Take 1 softgel daily, or as directed by your qualified health consultant. Warning: Do not use if under the age of 18, taking anticoagulant drugs (such as Warfarin) or other medications, or if at risk for any bleeding disorder (such as hemorrhagic disorders).
