Nattokinase is a natural enzyme extracted from natto, a traditional Japanese food made from fermented soybeans.
It’s best known for its ability to support healthy circulation and blood flow by aiding the body’s natural process of keeping blood vessels clear. Nattokinase works by breaking down excess fibrin — a protein that can thicken the blood and contribute to clots and arterial buildup — helping your cardiovascular system stay smooth and unobstructed.

Ours is double-strength, providing 4,000 Fibrinolytic Units (FU) in a single capsule, where many others offer only 2,000 FU.

We also use special delayed-release capsules to protect the enzyme from stomach acid, ensuring more of it gets absorbed where it’s needed most.

Plus, it’s freeze-dried for stability and comes in a 4-month supply.

Nattokinase is an enzyme that can be destroyed by the harsh, acidic environment of the stomach.

A delayed-release capsule is designed to pass through the stomach intact and open up in the small intestine. This ensures the enzyme is delivered effectively for maximum benefit.

No. Because Nattokinase supports healthy blood flow, you should not take it if you are on blood-thinning medications, have a bleeding disorder, or are preparing for surgery, without first consulting your doctor.

The effects of Nattokinase are often subtle and support long-term health rather than providing an instant feeling. Consistent daily use is key. Some users report feeling improvements in circulation over several weeks, but the primary benefits are in maintaining cardiovascular health over time.

Nattokinase can be especially important for people taking TRT or those who have a diet high in saturated fat.

Our Nattokinase is derived from non-GMO soy. While the purification process removes the vast majority of soy proteins, trace amounts may remain. Therefore, it is labeled as "Contains Soy," and we advise anyone with a soy allergy to avoid it or consult their doctor
