What are side effects of nattokinase?

ANSWER

In food, nattokinase is safe. More studies are needed to see if nattokinase taken as a supplement is safe for repeated or long-term use. Tell your doctor about any supplements you're taking, even if they're natural. That way, your doctor can check on any potential side effects or interactions with medications.
