Supplements and antiplatelet drugs.

Aspirin, clopidogrel and the additive-bleeding-risk supplements to flag.

Antiplatelet drugs (aspirin, clopidogrel) reduce platelet aggregation. A category of supplements does the same. Combining them is rarely catastrophic at typical doses but the risk profile shifts, especially around surgery, dental work, or any procedure where bleeding control matters.

Supplements with documented additive antiplatelet effects: garlic extract (allicin-standardised), ginkgo biloba, ginger at higher doses, fish oil at higher EPA/DHA, and high-dose vitamin E. The standard surgical rule is to stop these six weeks before any planned procedure. Curcumin and CoQ10 are sometimes named here, but the evidence for those two is weaker; they appear in the Amber tier as monitor-rather-than-stop.
