Roll Call does not check drug interactions or assess personal safety.
A flavonoid found in many plants, including celery, peppers, and chamomile, sold as an isolated supplement ingredient.
Why it’s used
Taken by some for its antioxidant properties and in the belief it may support a calm inflammatory response or seasonal allergy comfort.
What the evidence says
Laboratory and animal studies suggest luteolin has antioxidant and anti-inflammatory activity, but well-controlled human trials on oral luteolin supplementation are scarce, and there is no NIH ODS fact sheet covering it. Claims made for allergy or inflammation support in people are not well substantiated by current clinical evidence.
