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

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.
