Just thought it is worth sharing my experience with Nattokinase. Took it for a week without any other supplement, everything went fine even noticed a decline in the size of a small cyst.
Yesterday I took the supplement with Chaga mushroom, this morning I woke up and passed blood in my urine, little clots nothing major. Persisted throughout the day, went the GP they confirmed I have no infection and the GP and I both believe it is the Chaga interacting with the Nattokinase in a negative way, so I have no stopped Nattokinase and will stop all supplements for a few days to allow my body to reset.
Once this is done, I will resume with just chaga. Natto is good but make sure due to its blood thinning properties you are careful with what you mix it with.
Take care all, Joe

The other thing worth mentioning is to be very careful if you take nattokinase with Advil as it may cause blurry vision. I took an advil at night a few days ago to help with muscle stiffness and the next morning my vision was extremely blurry for the most of the day. Advil can cause blurry vision (one of the listed side effects), but I have never had that before. Worth noting. Would love to hear from other's experience. Can't find much about feedback from real people about nattokinase side effects on the web.
