If by “blood-thinning foods” you mean foods that may reduce platelet clotting or support cardiovascular health, there are several worth knowing. However, food is not a substitute for prescribed blood thinners such as warfarin, apixaban, or rivaroxaban.
7 foods with potential blood-thinning effects
Garlic 🧄 — Compounds in garlic may have mild antiplatelet effects.
Ginger — May modestly affect platelet aggregation.
Turmeric — Curcumin has anti-inflammatory and possible antiplatelet properties.
Fatty fish 🐟 — Salmon, sardines, and mackerel provide omega-3 fatty acids that support heart health and may modestly reduce platelet activity.
Cayenne/chili peppers 🌶️ — Contain capsaicin, which has been studied for cardiovascular effects.
Green tea — Contains compounds associated with cardiovascular benefits, although it can interact with some medications.
Berries 🫐 — Blueberries, strawberries, and other berries are rich in polyphenols and may support vascular health.
⚠️ An important warning
If an older adult is taking a blood thinner, don’t suddenly consume large amounts of garlic, ginger, turmeric, or green tea or start concentrated supplements without asking their doctor or pharmacist. Some can increase bleeding risk or interact with medications.
And if you’re asking because someone recently had symptoms suggestive of a mini-stroke/TIA, don’t try to treat it with food—seek emergency medical care immediately, even if the symptoms have disappeared.
