Nattokinase,
without the guesswork.

Nattokinase is an enzyme derived from natto, a traditional fermented-soybean food. “FU” stands for Fibrinolytic Units, the standard measure used to state nattokinase enzyme activity. NF provides a clearly labelled 5,000 FU per capsule, and the activity is checked on the finished batch. The labelled serving is one capsule daily.

Three practical things you can verify before ordering: (1) every finished batch is independently tested by an ISO/IEC 17025 accredited laboratory; (2) the batch certificate is published for you to inspect; and (3) the 5,000 FU activity, capsule count and serving are stated clearly. NF Nattokinase is manufactured in-house under GMP conditions rather than supplied as an anonymous proprietary blend. Open the testing database.

Speak with a qualified healthcare professional before use. This is particularly important if you take an anticoagulant, antiplatelet medicine, daily aspirin, blood-pressure medication or have a medical procedure scheduled. Follow the product label and your clinician’s advice.

Natto has been eaten as a traditional Japanese food for more than 1,000 years. Nattokinase as an isolated supplement is newer—it was identified in 1980—but it has since been examined in peer-reviewed human research lasting from 8 weeks to 12 months. A 12-month observational study reported no noticeable adverse effects, although it used a different dose and was not a randomized trial. That is useful background, not a universal safety guarantee. Follow the labelled serving and ask a qualified healthcare professional about ongoing use if you take medication or have a medical condition.
