Quercetin is a flavonoid, a group of plant compounds. It has many benefits thanks to its role as an antioxidant. [1] The substance can be found naturally in fruits, vegetables, and grains, among others. Not only that, but Quercetin can also be found in some of the best supplements.

One of its many health benefits is it reduces inflammation. According to a study, participants with rheumatoid arthritis felt notably reduced morning pain and stiffness. [2] Quercetin may also reduce both diastolic and systolic blood pressure. Trial results show that 500 mg of Quercetin daily helped lower blood pressure in diabetes participants. [3]

Moreover, this flavonoid can be an allergy reliever. Lab research involving mice shows that taking Quercetin supplements subdues peanut-related anaphylactic reactions. [4] Human studies are still needed, however.

Other benefits of Quercetin also include lowering risks of chronic brain disorders, slowing down the growth of cancer cells, aiding in athletic endurance, helping treat COVID-19, and many more. Although more studies are needed.
