Frequently Asked Questions

What are Fibrinolytic Units (FU)?

Fibrinolytic Units (FU) measure nattokinase's enzyme activity rather than its weight. Doctor's Best provides 2000 FU per capsule.

Can I take nattokinase with blood thinning medications?

Nattokinase is a dietary supplement and should never be used as a substitute for prescribed medications. If you take warfarin, aspirin, or other blood-thinning drugs, consult your doctor before use.
