Doctor's Best Nattokinase, Non-GMO, Vegan, Gluten Free, 270 Veggie Caps

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.

I've suffered in the past from high blood pressure and that's why I got this item. Occasionally when I eat salty foods my pressure rises to about 138/90. I bought this as an occasional supplement to help with this problem. So far I've used it 5-6 times and each time it has lowered my blood pressure within 1-2 hours by 20 points or more (both top and bottom numbers).The first day I received this I had eaten Chinese food and shortly after I had a headache even though I ate small portions. My pressure was high. About 8 PM I took 1 capsule of Nattokinase with water. About 10 PM I fell sound asleep on a chair while watching TV. When I awoke at 12:30 AM I immediately tested my blood pressure and was surprised that it went from 142/92 earlier (probably from the Chinese food) down to 104/71! That's why I was so tired.I didn't want to skip my prescription (5 mg amlodipine for HBP) so I took it and went to bed. My pressure must have gotten very low because I slept about 2-3 hours longer than usual.In the morning, after breakfast, my pressure reading was 112/72. Since that day I only use Nattokinase after a salty meal or if my pressure reading is more than 125/85 which,fortunately, is not very often. Also I carefully open the capsule and use a little more than half. This seems to work like strong blood pressure medication. Furthermore it works within 1-2 hours. I'm not sure if this can replace prescription medication but I will talk to my doctor about it next time I see him. Anyone get rid of prescription medicine and use this instead? It seems that if your pressure is moderately high (about 140/90) Nattokinase would probably be all you need. However, seeing your doctor about this is important because some people can have undiagnosed health problems which need to be addressed. Also when blood pressure goes above 140/90 it can lead to very serious health problems.So far I've found 3 products that definitely lower blood pressure here on Amazon. They are Reishi mushroom extract, Carditone and most recently Nattinokase. Although any of these work well I like the Nattinokase because the only side effect is to make you tired. Reishi upsets your stomach a little unless you eat first. Carditone works very well but it can sometimes make you feel a little sick if you take a whole pill. Many people have told me that half a pill works best. It seems that my first choice now will be the Nattinokase because it works well and has the least side effects. Also the capsules are very small and easy to swallow. This supplement surpassed my expectations and I highly recommend it to anyone who suffers from high blood pressure.

Easy to swallow size and price for quantity and quality superb.

By all accounts this is an effective product, and shows promise as a natural blood thinner. It may also be useful in helping the body combat biofilm (a factor in many diseases). (Nattokinase, lumbrokinase and serrapeptase are all effective for clearing biofilm. Some people like taking them together.)With that said, you do have to take some precautions. From Wikipedia:"Nattokinase may be potentially useful as a clot-buster and blood thinner, and is considered by some in the alternative medicine community as a possible adjunctive therapy in cardiovascular disease. There is some evidence for its effectiveness. Possible side effects have been reported. In one case, a patient concurrently taking aspirin and 400 mg of nattokinase daily for seven consecutive days to prevent stroke suffered an acute cerebellar hemorrhage."The point being, if you're going to use Nattokinase (not just this brand, but any brand), be careful not to mix it with other products that thin the blood. Even taking it with fish oil, a natural blood thinner, may be inadvisable. The patient above was trying to prevent a certain type of stroke, but may possibly have caused a stroke of the other type (cerebral hemorrhage), which is just as deadly.It has NOT been established that the combination of aspirin and nattokinase **caused** the patient's stroke. (It may have simply been a coincidence.) But to be on the safe side, it seems wise to avoid taking enzymes of this sort along with aspirin, warfarin, or anything else that thins the blood.

Great item speedy shipping at the best price.
