Taking devil's claw and turmeric together may increase the risk of bruising or bleeding. Both supplements can also lower blood sugar levels, which might cause them to drop too low if you are sensitive or taking diabetes medication. Additionally, both can increase stomach acid, potentially causing stomach upset or irritation.

Why this happens
Both devil's claw and turmeric have mild 'blood-thinning' properties (antiplatelet effects), which can have an additive effect when combined. They also both possess glucose-lowering properties. The black pepper (piperine) in the turmeric supplement is designed to significantly increase the absorption of turmeric, which may also inadvertently increase the absorption or slow the breakdown of devil's claw in the liver.
What you should do
Use this combination with caution. If you notice unusual bruising, nosebleeds, or bleeding gums, stop taking them and consult your doctor. If you have diabetes, monitor your blood sugar levels closely. It is best to take these supplements with food to protect your stomach. Always inform your doctor or pharmacist before starting these supplements if you are taking prescribed blood thinners (like warfarin) or stomach acid reducers.

Important precautions
Gallstones or bile duct obstruction
Both medicines stimulate bile production. If you have gallstones or a blocked bile duct, this can cause a painful gallbladder attack or worsen the blockage.
Stomach or duodenal ulcers
Devil's claw increases the production of stomach acid, which can severely irritate or worsen existing stomach or intestinal ulcers.
Blood-thinning medications (e.g., warfarin, clopidogrel)
Turmeric and black pepper can both thin the blood. Taking them with prescribed anticoagulants significantly increases your risk of serious bruising or internal bleeding.
Food and drink warnings
Alkohol
Devil's claw can increase the production of stomach acid. Combining it with alcohol, which also irritates the stomach lining, may increase the risk of stomach upset or gastric ulcers.
