Can I take Black garlic and Turmeric with black pepper together?

Why this happens

Both black garlic and turmeric (curcumin) have antiplatelet effects, meaning they make the cells in your blood less 'sticky'. When used together, they have an additive effect on preventing blood clots. Additionally, the piperine in black pepper inhibits certain enzymes in the liver and gut that normally break down supplements, which can lead to higher levels of these substances staying in your system for longer.

What you should do

This combination is generally safe for healthy people in normal food amounts, but you should use caution if taking concentrated supplements. If you notice unusual bruising, nosebleeds, or bleeding gums, stop taking them and speak to your doctor. You must avoid this combination if you are already taking prescribed blood thinners (like warfarin, clopidogrel, or apixaban) or if you have a scheduled surgery, as it could cause excessive bleeding.

Important precautions

Surgery or dental procedures

Both black garlic and turmeric can thin the blood and increase the risk of bleeding. You must stop taking these supplements at least two weeks before any scheduled surgery or dental work.

Blood-thinning medications (e.g., Warfarin, Clopidogrel, Rivaroxaban)

These supplements can significantly increase the effect of blood-thinning medicines, raising your risk of bruising or serious bleeding. Do not combine them without medical supervision.

Gallstones or bile duct obstruction

Turmeric stimulates the gallbladder and can cause painful contractions or blockages if you have existing gallstones or bile duct issues.

Food and drink warnings

Alcohol

Both black garlic and turmeric may have mild blood-thinning effects. Excessive alcohol consumption can also thin the blood and increase the risk of stomach irritation. Combining them may increase the risk of bruising or gastrointestinal bleeding.

Grapefruit juice

Black pepper contains piperine, which, like grapefruit juice, can inhibit certain enzymes (CYP3A4) responsible for breaking down medications. Consuming large amounts of both may significantly increase the levels of other prescription medicines in your system.
