Side Effects of Curcumin and Turmeric
Question: What are the side effects of curcumin and turmeric?
Answer: Turmeric/curcumin supplements are generally safe, but gastrointestinal side effects may occur with higher doses and they can cause problems for people with gallbladder disease, kidney stones, or those taking blood-thinning, blood-sugar-lowering, or immunosuppressant medications. Curcumin may also inhibit iron absorption. Be aware that black pepper extract (piperine) often added to curcumin to increase bioavailability also interacts with a number of medications.
Although rare, elevated liver enzymes and liver injury have been reported with the use of turmeric/curcumin supplements.
