Documented concern — monitor and disclose
Clinically relevant documented concern. Disclose the supplement to your clinician and keep monitoring in place.
Mechanism and evidence
DOAC labels warn about bleeding with antiplatelet herbs; garlic inhibits platelet aggregation by changing platelet function.
Evidence tier: label-mechanistic
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 prescriber about garlic supplements on a DOAC.
- Report unusual bruising or bleeding.
