Taking black garlic and ginger together may increase your risk of bruising or bleeding. This is because both supplements can slow down the time it takes for your blood to clot.

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.

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.
