Great product, independently lab tested
Excellent product. I had previously purchased a 'lipomal" nattokinase here, but it was no name and I didn't see any results. After reading a Consumers Lab report on nattokinase, I saw that there are many brands which have little to no actual natto. This brand was found to consistently contain over 150% of the label claim, to accommodate depletion with shelf life and to assure users they are getting the full benefit. After a few weeks, I to see great BP readings and feel confident that I'm getting the real thing to help address my CVD. Great price per dose too. To assure that I'm taking the amount shown beneficial in clinical trials (12k FU), I take 5 capsules daily (10k x 150%).

It is a great product for SOME people
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.

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.
