Jarrow Formulas MK-7 -- 90 mcg - 60 Softgels

Vitamin K2 as MK-7. Natto K2 Natto Extract. Bone and Cardiovascular Health 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.

"I have been using Jarrow's MK-7 for a few years, very happy with it. If allergic to soybeans, avoid this product, as it clearly states that it is derived from non-GMO fermented soybeans (natto)."

Caution with this product, February 15, 2009
By lorifr1 from Connecticut

"I was very excited to get this product, and looked forward to the first day I would start taking the vitamin. To my dismay, I had an allergic reaction to the soy base in the vitamin. The write-up does not clearly state that this product is made with soy, and so I had to give this product away to a coworker. I was very disappointed."
