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
