Dangers of Nattokinase

Pretty upset right now. My stomach has been hurting on and off for the past week and a half, it's been doing it more since last night, I actually woke up with a bit of pain last night. Nothing extreme, but enough to wake me up. I mentioned before that I have stomach ulcers, and I think they are what make my stomach so incredibly sensitive to when I eat out, which I've been doing more since last Sunday. It only occurred to me tonight, after I ate dinner and my stomach began hurting, that since I have ulcers and Nattokinase is a blood-thinner, that the Nattokinase is probably what has been contributing to my stomachaches. I looked it up, and lo and behold, the website says, 

"Nattokinase should also not be taken by those who bleed very easily. It should be avoided by those who have recently had a bleeding ulcer, surgery, stroke or heart attack." 

This is all even more upsetting to me because my health has been feeling a bit more poor in different ways as well, and I can't be certain, but I wonder if my elevated heart rate during my work outs was not attributed to the Nattokinase in my system. As I said to a friend last night who said I should live it up more, "my health is a full time job." It gets incredibly frustrating when I have setbacks such as these. I was doing really well on the Serrapeptase and Liquid Chlorophyll alone and I really should have done more research before adding Nattokinase to my diet. It should have popped out at me that it was a blood thinner, but then again, I really wanted to be rid of the clutches of this disease. 

So this is where I am now, my ulcers are once more proving to be a problem when I eat, and it will take several weeks before they heal sufficiently to not bother me anymore. I'm not sure if they will ever heal completely, hence my absolute and essential need to stay away from blood-thinners, Ibuprofen, and anything else that might irritate them. Really can't say how frustrated I am about my ulcer situation, but I gotta press on. My warning to everyone is to really do your research before you add anything new to your diet, please look into the side effects. I still suggest eating a diet high in Thiocyanate and eat healthy in general. Eat as natural as possible because that's always best for your body.
