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.
