    A: FU is the standardized activity unit for nattokinase — it measures the actual enzymatic activity rather than just mass. A 100 mg serving with 2,000 FU is half as potent as a 100 mg serving with 4,000 FU. Premium nattokinase supplements list FU prominently. NatureBell's 4,000 FU per serving is in the well-studied clinical range used in cardiovascular research.

    A: Nattokinase is the specific enzyme isolated and purified from natto. Natto itself is a fermented soybean food eaten in Japan with a distinctive sticky texture and strong flavor that many Western palates find challenging. Nattokinase capsules deliver the studied enzyme without the texture or flavor. The supplement also avoids the high Vitamin K content of natto, which is important for those on blood thinners.

    A: Yes — talk to your healthcare provider before combining nattokinase with prescription blood thinners (warfarin, clopidogrel, aspirin, NOACs). Nattokinase has fibrinolytic activity that may compound the effects of these medications. Discontinue use 2 weeks before any scheduled surgery. People with bleeding disorders should also avoid use without medical guidance.
