Garlic’s sulphur compounds have documented effects on platelet aggregation and fibrinolysis. If you are taking warfarin, direct oral anticoagulants (apixaban, rivaroxaban, dabigatran, edoxaban), aspirin, clopidogrel, or any other antiplatelet or anticoagulant medication, you must consult your prescribing doctor or pharmacist before starting this supplement. The interaction can increase bleeding risk, and dose adjustments or monitoring (INR for warfarin users) may be needed.
Similarly, stop the supplement at least 7–10 days before any scheduled surgery, dental extraction, or invasive procedure, and inform your surgeon and anaesthetist. Restart only after your medical team confirms it is safe.
Pregnant and breastfeeding women should seek professional advice before use, as concentrated garlic extracts have not been studied in these populations. Anyone with a known allergy to Allium species (onion, leek, chive, shallot) should avoid the product.
Combining one capsule daily with vitamin C, zinc, echinacea, or a multivitamin is a common seasonal regimen and is generally well tolerated. Space the garlic capsule and any iron supplement by at least two hours if you take both, as sulphur compounds can bind minerals. Always read the full label and do not exceed the recommended serving.
