WARNING !!!! Nattokinase can have very bad side effects
Posted by Reviewer3202446 on Sep 01, 2012
I easily have bruises on my legs, more particularly when I'm trekking. Therefore I thought that product would help me. I could clearly feel the sensation in my legs and it was really agreeable the first week. But one morning I woke up with huge shocking bruises on my legs and behind my left hip. Finally we discovered that to scratch (insect bite) have been enough to create those. The next days, my capillaries broke all along my legs... When I understood the cause and effect with nattokinase, I stopped the treatment of course. Since then I have been treating my bruises with arnica. Be careful !

I started taking nattokinase after reading positive reviews and learning that I have a genetic tendency for DVTs and PEs (and clot extremely heavily during menstruation). I had only been taking this product for about two weeks when I noticed that my veins are far more pronounced now and I have bruises all over my body where I never have had that tendency before. I am stopping taking this product as I believe it is probably working far too well and has thinned my blood out too much to produce these sort of effects. I was only taking 1 pill each day. I truly hope to see a reduction to the bruising and noticeable veins soon. Be careful taking this product.

I have been using it for nine months, for the prevention of thrombotic events, and so far it seems to be doing the job.

I ordered this for my mother. She has pretty bad blood circulation and due to this she has high BP. After feww weeks on these pills, she feels much better and the BP stared to go down. Will keep reorder them for her****
May help to prevent Alzheimer's disease
Posted by good-day on Apr 20, 2014
I have a family history of Alzheimer's disease, one of the reasons I take nattokinase to prevent it from happening to me later in life. In addition to nattokinase, I am also taking fish oil, spirulina and CocoCardio and I have written reviews for these products as well. You are welcome to check them out on my product review page (good-day).
Worth a try

I have been taking Serrapeptase,Nattokinase and Acetyl-L Carnitinne with Alpha Lipoic acid after developing peyrones disease and scarring on a coronary stent. My doctors could not offer an explanation of what was happening and I felt terrible even though blood tests and ateriogram showed good results after a new stent was inserted. I read as much as I could and discussed with my doctors the possibility that I was suffering from some kind of underlying inflammatory condition. Since the doctors could not offer any other options, (I already take a bucket of daily medications and exercise regularly)I decided to try these as supplements. After 6 months the peyrones disease effect seems to have eased rather than progressed and I have had a thorough physical and blood tests which showed normal results. More importantly, I do not feel like I am walking through treacle just to get out of bed and go to work. My doctors are encouraging me to stick with the supplements as they can see not detrimental effects on my blood chemistry or blood enzyme activity. I definately do feel better and think it is worth my while to persist with these supplements.I feel I should add the rider that my view is these are supplements to a careful diet and regular exercise. Diet and exercise provide the foundation on which to re-build health. cheers, Brad
Blood clot protection

We like this product because it is made from non-GMO soybeans and has the K2 removed. We use it to help protect against blood clots causing strokes, heart attacks or phlebitus.

I am 71. Three months ago, I noticed my pulse was "missing beats", maybe one in six. After EKG and Holter monitor, my doctor and a cardiologist he consulted diagnosed me with PAC (premature atrial contraction) and PAT (paroxysmal atrial tachycardia), but it wasn't serious enough for medication yet, though he did recommend magnesium. He said come back and see me in a while. Since then my pulse seemed to get more irregular, despite magnesium aspartate. I searched reviews on iherb and found Doctor's Best Nattokinase. I took four capsules a day. Within a week my pulse was totally even and the rate around 70 (from 100). I am also much more energetic and can feel my blood flowing. To me this is a small miracle! Thanks.

I'm a very active 62 year old male in good health and physical condition. However, I recently experienced severe "burning" pain in the calf muscles of both legs. My doctor examined me and informed me that I had developed P.A.D.s (peripheral vascular disease). I've always walked 3-5 miles daily, but with the onset of this condition walking is "extremely" painful. The doctor informed me that I should keep walking and eventually the "burning" pain would become less severe and hopefully go away entirely. In the meantime, there was nothing he could prescribe to eliminate the "burning" while walking! While talking with my my aunt one day, she suggested that I try Doctors Best, Best Nattokinase. Upon receipt of the product I took one capsule that morning and another that evening. The next morning I went for a 4 mile walk and you guessed it, "No more burning pain"! And, I continue to take two capsules daily.
Good product at a good price

It helped my wife. It cleared a blocked artery. She was to have surgery, but did not need it after taking nattokinase.
