Be careful!

Purchased at iHerb

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.

Blood Thinning

It seemed apparently to work in the early stages - I had to stop as I started to bleed which was very worrying. Stopped bleeding once stopped taking this product. I have no disorder to be affected like this.

Vitamine K was removed and I did not realize that before I bought this brand. I want K to help my bones and this product not only says it has removed it but says do not take with product containing K. So, it is in the drawer with the products that are bought and rarely used. My accupuncturist had originally recommended I take Nattonkinase, but it was another brand.

Did not feel any appreciable, positive cardiovascular improvement. If you neuropathy, please beware of taking this on a daily basis. I did and found that it makes my arm numb, 'go to sleep' and suspect that it is due to the presence of Vit K. The manufacturer insists that it doesn't contain Vit K - that it has been purposely removed in favor of Nattokinase. Doesn't appear to be true - so beware! Will not this again.
