Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo pill contains three ingredients, but the one that matters here is the aspirin. Aspirin is a blood thinner that keeps your platelets from clumping together, so it already nudges you toward easier bruising and bleeding. Serrapeptase is an enzyme that, at least in lab studies, seems to help break down clots too. Stacking the two together could, in theory, add up and raise your bleeding risk a bit more.

I want to be honest about how soft this evidence is. It comes from test-tube work, not real patients, so it's a maybe, not a proven problem. Still, keep an eye out for things like nosebleeds, bleeding gums, or bruises that show up out of nowhere. Before adding serrapeptase, run it by your pharmacist or doctor first.
