Nattokinase For a Healthier Heart Health!

What is Natto and Nattokinase?

Did you know that Japan is home to the oldest population in the world? Japanese individuals have been eating their way to better heart health for centuries and their secret may lie in a simple food called natto, a fermented soy product rich in nattokinase. Natto is fermented with a probiotic bacterial species (Bacillus subtilis) that promotes gastrointestinal health. Nattokinase is a potent blood-clot dissolving protein used in supporting cardiovascular and heart health.

Why Take Nattokinase Supplements? While it is popular in Japan, it is an acquired taste. Eating natto to support a healthy heart may not be for everyone. Natto has a slimy texture, pungent aroma and a distinct flavor comparable to fermented cheese. You may be better off taking tasteless orally nattokinase supplements, the best way to deliver the enzyme throughout your body without having to eat the not-so appealing natto!

Nattokinase Supports Healthy Circulation Nattokinase is known as a potent fibrinolytic enzyme that is extracted and highly purified natto. Years of scientific research demonstrated that nattokinase improves blood circulation. Nattokinase decreases the ability of blood to clot - it "thins the blood" and may help protect against conditions caused by blood clots.

Unlike aspirin, nattokinase doesn’t irritate the stomach! Many studies have shown the positive effects of nattokinase on maintaining healthy blood pressure as it allows better blood circulation throughout the body. Additionally, it may be good to take nattokinase on long flights and other situations that require you to remain seated for prolonged periods to help support blood circulation.

Eating natto or taking nattokinase supplements may be one of the safest ways to naturally improve your cardiovascular health and increase your chances to live a long and healthy life!

Doctor's Best Nattokinase uses the highest quality nattokinase manufactured and independently tested at the industry recognized enzyme manufacturing facility, Deerland Enzymes in Kennesaw, Georgia. We believe by utilizing this manufacturing technology we are providing the highest quality nattokinase available.

An EXCELLENT natural remedy for hypertension

Reviewed in the United States on June 9, 2023

Style: SupplementsVerified Purchase

I had obesity-induced hypertension. I use "had" because within 48 hours of taking 4 pills of nattokinase, in conjunction with 4 pills of serrapeptase every day, I dropped from 151/97 to 116/76. I had not lost a pound of weight. Nothing has changed in my dietary and living habits except for taking natto and serra together. Now, I wouldn't recommend others go as overboard as I did initially, taking 8 pills a day. But, I weigh a lot and needed to throw 'everything' at my body. It's been over 2 months now and my blood pressure has remained remarkably low. Two days ago, I was at 111/77. I'm no longer in the BP danger zones. Every single day since I began taking natto and serra, and I'm a heavy coffee drinker by the way, I need it for my highly intensive job, I've been consistently low in my sys/dias numbers.

I take natto and serra every day now. I have lowered my pills to 4 and 3 respectively, sometimes the reverse, sometimes one pill of each. One side effect I've noticed with taking natto and serra is my huge appetite has been suppressed. I don't eat as much as I used to so I've lost about 10 lbs in the last two months without doing anything. I still eat stuff I shouldn't but those hunger pangs that come at ungodly hours of the night between 8 PM and 2 AM, which is how I gained all that weight in the last two decades, have subsided.

Google "nattokinase and serrapeptase", you will find online medical articles and other research on the benefits of taking the two together. I'll come back here in a year to update. This is a miracle! If I shared how much I actually weigh, even now, all of you will be SHOCKED and AMAZED that a person of my size has systolic/diastolic numbers so low. It's unheard of! No wonder the Japanese, who drink natto tea all day and night, have the largest number of citizens over age 100 in the whole world. They're on to something.

I take no meds whatsoever, no meds at all for anything. I had no medical issues except for the obesity-induced hypertension so I had refused to take meds for it and tried for decades to lose weight naturally. I only take mutivitamins. Hope this helps someone. This is a game-changer!

nattokinase helps dissolve fibrin such as often remains in occluded blood vessels after DVT / blood clots

Reviewed in the United States on December 10, 2012

Style: SupplementsVerified Purchase

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. Despite having multiple diagnosis leaving me permanently disabled and my leg rather disfigured, *all* of my medical professionals (including a podiatrist, interventional radiologist, vascular surgeons, cardiologists, hematologists, etc) are stunned at how healthy my leg appears DESPITE my very well documented medical saga. Yes, my leg is still obviously disfigured and likely always will be, but the skin appearance is visibly improving and healthier as compared to others suffering a similar set of complex diagnosis stemming from chronic recurrent DVTs.

The supplements that go well with nattokinase for leg vein health after DVT include: fish oil, flax seed oil, a whole food sourced multi such as New Chapter Every Woman's One Daily, 72 Count , vitamin D, vitamin K2/mk7 (only if NOT taking warfarin!), B vitamins such as NOW Foods B-12,Liquid B-Complex, 8 ounce , magnesium, horse chestnut, garlic, parsley, as well as red wine as explained to me by a D.O. whom I consulted a couple years ago. The medical professionals generally cannot offer alternatives but will discuss their virtues when asked! Keep in mind if you have any chance of getting "real" information from medical professionals, only have these discussions when storm troopers (pharmaceutical reps) are not around; watch for those all too frequent catered lunches they tend to provide to the most indoctrinated...

Potent Circulation Support Without the Clot-Busting Side Effects

Reviewed in the United States on September 24, 2023

Style: SupplementsVerified Purchase

As someone interested in trying nattokinase for blood flow and circulation support, I opted for Doctor's Best natto-serra supplement. It provides potent enzymes without risk of bleeding side effects.

The nattokinase is harvested in a way that enhances its fibrinolytic activity to break down blood clots and plaque. After a few weeks, I noticed improved circulation and energy.

What I really appreciate is that this formula pairs nattokinase with serrapeptase for dual circulatory benefits. These enzymes promote vascular health without thinning the blood too much like other options.

For those looking for effective nattokinase without the major clot-busting side effects, Doctor's Best is a great option. I've been able to safely improve my circulation with this dual enzyme formula. My cardiovascular health thanks me!
