Can I take Black garlic and Ginger together?

Why this happens

Both black garlic and ginger have 'antiplatelet' properties. This means they make the small cells in your blood (platelets) less 'sticky', which prevents them from clumping together to form clots. When used together, this effect is added together (additive effect), making the blood thinner than usual.

What you should do

For most people, using these together in normal food amounts is fine. However, if you are taking them as concentrated supplements, you should be cautious. Stop taking both at least two weeks before any scheduled surgery or dental work. If you notice unusual bruising, nosebleeds, or bleeding gums, stop using them and speak to your doctor. Avoid this combination if you are already taking prescribed blood thinners like warfarin, aspirin, or clopidogrel.

Important precautions

Surgery or bleeding disorders

Both black garlic and ginger can thin the blood and increase the risk of bleeding. You must stop taking these at least two weeks before any planned surgery or dental procedure.

Taking blood-thinning medication (e.g. warfarin, clopidogrel, aspirin)

These supplements can significantly increase the effect of blood-thinning medicines, making you more likely to bruise or bleed dangerously. Do not combine them without medical supervision.

Gallstones

Ginger increases bile production, which can trigger a painful blockage or gallbladder attack if you have a history of gallstones.

Food and drink warnings

Alcohol

While there is no direct chemical interaction, both black garlic and ginger can have mild blood-thinning effects. Excessive alcohol consumption can also thin the blood and increase the risk of stomach irritation. Combining large amounts of these supplements with heavy drinking may increase the risk of bruising or bleeding.
