It caused high blood pressure and a fast heart rate This is my case maybe will work for others

I buy this product since a long time. Perfect health resultates. The price is attractive by good quality.

Great!!!! product will buy again.

Tiene maltodextrina que aunque justifiquen que es para preservar el producto, esto bien lo pudieron haber omitido porque simplemente no es necesario y no es bueno para la salud.

I think this is the genuine product available in market.

I have read about this product for a while and did a lot of hunting to find it at a great price and so far this happens to be the best price I could find and it has the right amounts in it. 2,000 Fu seems to be the proper rating. Thanks to those folks in Japan that figured this out back in the 1980's according to what I have read. I wish I had known about this a long time ago. I like that it can dissolve blood clots and other good things that this does. I have just started using this so I will see if this will make me not feel as sluggish with thinner blood. Some articles say that this is kinda like renewing the blood. I like that now that I am in my 50s. If this stuff will make me feel like i am in my 20s I will write another review. I will share good things with people if it works as it is supposed to. It hass a funny name but it does good things.

I felt obligated to write a review about "Doctor's Best Best Nattokinase (2, 000 Fu)" because the improvement my family felt over last 2 years. You are right, 2 years, which qualifies me to write a meaningful review on it. Why did my family start to use it? My father had a heart attack two and a half years ago. The ECG & MRI diagnoses were not good and he also had Embolism. With traditional treatment, I started looking for additional supplements that could help. After some research, I found Nattokinase could be one choice and "Doctor's Best" is quite reputable with very reasonable price. So everything happened there. What is the benefit? The improvement is STEADY and HUGE. AFTER CONSULTING THE DOCTOR, my father started taking the 2k Fu pills everyday. Because some worries about potential risks (see below), I asked him to take 1 pill a day in warm seasons and 2 pills a day in cold seasons, and asked him to regularly do the blood tests. After 1 year, the ECG result showed an improved T-wave from -4 to -3 (I'm not professional and the numbers are direct readings from the ECG curve which was explained by the doctor "a good sign of improvement"). And last week, after 2 years of taking the pills, the T-wave is lifted from -3 further to -2 plus significant improvement in body feeling. According to the doctor, this is GREAT! What is the other benefit? I started to take it about 1 year ago because my blood pressure is a bit high and I know my blood is very viscous. I constantly monitored my blood pressure afterwards and found that it decreased from average low@86~high@131 to low@75~high@119 in about a year. I'm not taking any other blood pressure control pills and my diet habit is the same. So this is definitely due to Nattokinase. And I'm happy about it. What are the RISKS? While doing the research before buying, I noticed there is a scientific paper (published) discussed the improvement of blood mobility (reduction of viscosity) after treatment of Nattokinase (many adults were taking the pills and their blood samples were tested over some time period). And then there are reports stating that longer time is needed to stop bleeding and unexpected bleeding occurs while some people brushing the teeth after taking Nattokinase. So I think there must be risks about it. And indeed, my mom can't take it because several days of Nattokinase intake would always cause her teeth to bleed after brushing. So for those who have this kind of problem, be careful. The best way is to always consult your doctor before taking and when anything unusual happened after taking. In summary, Pro: It worked in my cases; Pills are small; "Doctor's Best" is a good brand. nothing really bad, you just need to know if it fits you.
