Is Nattokinase legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
No. Nattokinase is not an approved medicine in Canada. Its legal category is "Sold as a natural health product; needs a Health Canada product licence and a product number (NPN)". Nothing that contains it is allowed for any use in people. Vials labeled "for research use only" get no exception: that label does not make them legal to use in people. On the evidence, 9 completed human trials are cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
No product containing Nattokinase is approved by Health Canada for any use in Canada. So nothing on sale is allowed for use in people.
- 02
"Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.
- 03
Importing it, supplying it or promoting it for use in people can fall under medicines law in Canada. This page is general information, not legal advice.
What Nattokinase is
Nattokinase is a clot-busting enzyme made when bacteria ferment soybeans into natto, a Japanese food. For a supplement, it has a big human trial record. That includes blood pressure trials against a dummy pill and a 3 year trial with one. There is no trial of heart attacks or strokes. And its famous plaque result did not use a dummy pill for comparison.
Nattokinase is a 275 building block enzyme. It is made when the bacterium Bacillus subtilis natto ferments boiled soybeans into natto, a food eaten in Japan for centuries.
How it works: Nattokinase works in several ways at once. It breaks down fibrin, the mesh that holds clots together, and fibrinogen, the protein fibrin is made from.
Approval history: Sold as a dietary supplement under the US supplement law. It is not an approved drug, and the FDA has never checked it for safety or whether it works. A label may say how it supports the body, such as supporting healthy blood flow, if it carries the required disclaimer that the FDA has not checked the statement. It may not claim to treat, prevent, or lower the risk of a disease. In August 2020, the FDA sent a warning letter to a supplement seller. The seller had marketed a product with nattokinase in it as able to cut plaque build-up in the arteries and help prevent a heart attack or stroke. The FDA said those were illegal disease claims, no matter what the research showed.
How Health Canada treats this kind of product
Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.
The legal category above is how The Longevity Archive reads Health Canada, Health Products and Food Branch listings for Nattokinase on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Nattokinase in sport and the military
Whether Nattokinase is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Canada. Before you compete or get tested, look up Nattokinase by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
