Both turmeric and rosehip have mild blood-thinning properties. Taking them together might slightly increase the risk of bruising or bleeding, especially if you are already taking prescribed blood thinners or have a scheduled surgery. Additionally, the black pepper (piperine) in the turmeric supplement can increase the absorption of many substances, potentially making the effects of the other ingredients stronger than intended.

Why this happens
Turmeric (curcumin) and rosehip can both interfere with how platelets clump together to form clots. Furthermore, piperine (from black pepper) inhibits certain enzymes in the liver and gut that normally break down supplements and medicines, which can lead to higher levels of these substances in your bloodstream.
What you should do
This combination is generally considered safe for most healthy people, but you should use caution. If you notice unusual bruising, nosebleeds, or bleeding gums, stop taking them and speak to your GP. If you are due to have surgery, stop taking these supplements at least two weeks beforehand. Always inform your doctor if you are taking these alongside prescribed anticoagulants like warfarin or aspirin.

Important precautions
Surgery
Stop taking this supplement at least 2 weeks before any scheduled surgery. Turmeric can thin the blood and increase the risk of dangerous bleeding during and after the procedure.
Gallstones or bile duct obstruction
Do not use this supplement if you have gallstones or a blockage of the bile ducts. Turmeric stimulates the gallbladder, which can cause severe pain or worsen a blockage.
Kidney stones
Avoid high doses if you have a history of kidney stones. The vitamin C in rosehip can increase the amount of oxalate in your urine, significantly raising the risk of forming new stones.
Food and drink warnings
Alcohol
Vitamin C can speed up the rate at which your body breaks down alcohol. While not dangerous, it may slightly alter how you feel after drinking.
High-fat meals
Turmeric and black pepper are better absorbed when taken with foods containing fats (such as oils, avocado, or dairy). Taking them on an empty stomach may significantly reduce their effectiveness.
