Can I take Ginger and Turmeric with black pepper together?

Why this happens

Both ginger and turmeric have 'blood-thinning' properties (they slow down how quickly blood clots). Black pepper contains piperine, which stops the liver from breaking down turmeric as quickly, leading to much higher levels of turmeric in your bloodstream. This combination creates a 'double whammy' effect on your blood's ability to clot.

What you should do

This combination is generally safe for healthy people in normal food amounts. However, if you are taking high-dose supplements, you should be careful. Stop taking these at least two weeks before any planned surgery. If you notice unusual bruising, nosebleeds, or bleeding gums, stop the supplements and speak to your GP. Do not use this combination if you are already taking prescribed blood thinners like warfarin or aspirin without medical advice.

Important precautions

Gallstones

Ginger can increase the production of bile, which may cause a blockage or pain if you have gallstones.

Turmeric stimulates the gallbladder to produce bile, which can cause painful contractions or blockages if you have existing gallstones or bile duct issues.

Bleeding disorders or use of anticoagulants (e.g. warfarin)

Both ginger and turmeric can thin the blood and increase the risk of bruising or serious bleeding. Black pepper (piperine) further increases the absorption of turmeric, potentially enhancing this effect.

Scheduled surgery

Due to the increased risk of bleeding, you must stop taking these supplements at least 2 weeks before any planned surgical procedure.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol when taking these supplements. Both ginger and turmeric can have mild blood-thinning effects, and alcohol can further increase the risk of bleeding or irritate the stomach lining.

Caffeine (Coffee, Tea, Energy Drinks)

Ginger can speed up the movement of food through the digestive tract. When combined with caffeine, which is a stimulant, this may lead to an increased risk of stomach upset, diarrhoea, or a racing heartbeat.

Grapefruit juice

Grapefruit juice can interfere with how your body processes certain compounds. Because black pepper (piperine) is added to turmeric to increase its absorption, grapefruit juice may further increase levels of the supplement in your blood, potentially increasing the risk of side effects.
