Nattokinase Topic

Dear Dietitian,
I have read that one should take nattokinase on an empty stomach to enhance absorption. Nattokinase is a significant source of vitamin K2 (MK-7), which is a member of the fat-soluble vitamin K family; it is required to be taken with fat to be absorbed. It seems that the nattokinase needs to be taken on an empty stomach, but the vitamin K2 needs fat to be absorbed, which are two opposite things. My question is how can you take nattokinase on an empty stomach but also with fat in a meal?

Hello Kedone1-
You are correct- For enhanced absorption, vitamin K-containing foods and supplements should be taken with some healthy dietary fat. I'd suggest talking with your doctor about when to take this supplement based on your health unique health conditions. Have a great day! Joanna (MyNetDiary Dietitian)
