It is an enzyme produced during the fermentation of soybeans into natto. It is sold as a supplement, usually described by FU (fibrinolytic units) rather than milligrams alone.

How much is in each capsule?

Each capsule supplies 100 mg of nattokinase, standardized to 2000 FU. The bottle holds 90 vegetarian capsules.

Are the capsules vegetarian?

Yes. The capsules are vegetarian, so they avoid the gelatin used in many enzyme supplements.

Nattokinase is made from fermented soybeans, so people with soy concerns should check with their doctor before using it.

How does it compare with combination enzyme products?

This is a single-ingredient nattokinase. Rivals often pair nattokinase with serrapeptase or other enzymes, which gives more ingredients but makes the dose harder to compare.

People on blood thinners or with bleeding disorders, and anyone scheduled for surgery, should talk to a doctor first, since nattokinase affects clotting.
