Documented concern based on cited evidence — not a personalized safety check, not medical advice, and not a decision to combine or avoid. That decision belongs with your prescriber.
Documented concern — monitor and disclose
Clinically relevant documented concern. Disclose the supplement to your clinician and keep monitoring in place.
Mechanism and evidence
Garlic inhibits platelet aggregation, which adds to warfarin anticoagulation rather than opposing it; electronic health record screening flags garlic among warfarin-relevant supplements.
Evidence tier: mechanistic-ehr
The tier names the strongest cited study design. Some anchors studied the supplement on its own, or a related drug in the same class — in those pairs the grade rests on that evidence plus established pharmacology, as agreed with our medical reviewer.
What to discuss with your prescriber
- Tell your anticoagulation team about garlic supplements.
- Report unusual bruising or bleeding.
