My husband has a blood clotting disorder and was placed on Coumadin for life. He wasn't doing well on Coumadin. There was so many nasty side effects so we looked for an alternative to Coumadin. This supplement was recommended to us 10 months ago. He is doing so much better since taking Nattokinase. He is off of Coumadin (without his Dr's blessing), it has brought his cholesterol down, brought his blood pressure down (along with vitamin C), and improved his cataracts. He just had an eye exam and his eye glasses prescription was the same as two and a half years ago. That has NEVER happened. His eyes have always gotten worse for every exam. His Dr wasn't happy with him when he got off of Coumadin, but he is happy with the results and can't believe hubby is off of cholesterol and high blood pressure meds. He has never see that happen in his patients. We are excited to see other benefits pop up in the future.

Nattokinase is currently being studied as an effective way to dissolve fibrin and thrombus (blood clots) in study animals (usually rats) as well as in humans. As someone who has suffered and endured more DVTs (Deep Venous Thrombosis) than can be counted across a couple decades and suffers from virtually all the possible complex complications stemming from multiple complete occlusions (including Post Thrombotic Syndrome (PTS), May Thurner Syndrome (MTS), Chronic Venous Insufficiency (CVI), chronic lymphedema and veins that have become destroyed from too many years of warfarin therapy - never again, no matter what, my body simply cannot tolerate the inflammation from warfarin anymore...) finding an effective way to both PREVENT as well as DISSOLVE blood clots is vital for my quality of life.

The many medical professionals I have consulted over the years never explained a basic concept to me - today's oral anti-coagulation therapies are ONLY designed to "prevent" further DVT (which is really ironic considering I always develop extensive new clotting while on warfarin therapy!) There are NO oral medications for "dissolving" existing blood clots OR fibrin which is vital to preventing further complications such as those from which I suffer and have endured. Thankfully for various reasons I was never a good candidate for any of the invasive procedures being tried over the years - whether bypass the MTS, or vena cava filters nor stenting as is being tried in recent years - they all seem to all too frequently cause further cascading series of events that are often very detrimental to quality of life.

I have incorporated nattokinase into my supplement regimen the past few years on a periodic basis as I can afford with obvious success; this is called evidence based experience.

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.

I take Nattokinase along with the Serrapeptase( hope spelling is right).
every morning and I've not felt this great in a long time nor did I ever have an active lifestyle.

I feel refreshed everyday all day and in always a great mood; alot of suppplements I used take I've
stopped taking because of this amazing product.

No longer feel like a slugg, I feel like a very healthy woman!!!

My wife, 63, has been taking Nattokinase -- two per day -- for the last six to eight weeks. It seems to decrease the systolic pressure by 10 to 20 points and the diastolic pr by about 5 to 8 points. We have tried to test that by her skipping it for a day or two and BP rises back to its old level. She is able to take this (or any such) supplement only when it is truly vegetarian and we are glad that the Dr Best's brand has it available.
