Do you eat a whole onion every day? Probably not. Neither do we. (Pass the mints please...) All jokes aside, unless you are one of the few who can claim this unusual feat, you may not get a good amount of Quercetin in your daily meals. In comes quercetin supplements to the rescue! Quercetin is a flavonoid polyphenol that is naturally present in fruits and vegetables such as apples, berries, grapes, onions, broccoli, and many other foods. By scavenging radical oxygen species, quercetin is an antioxidant and exhibits anti-inflammatory, anti-microbial, anti-allergic, and antiviral activity. Most recently, it became popular as a potential partner in anti-aging stacks due to its senolytic activity in in vitro models, which can make DNA repair more efficient.

Quercetin helps decrease blood pressure and improve the symptoms of type 2 diabetes. Quercetin can reduce symptoms and pain of inflammatory conditions, such as rheumatoid arthritis. In combination with other cell-stimulating drugs, quercetin has the potential to improve cell regeneration and slow down aging. Efficacy Studies A prospective non-randomized clinical study of 20-25 patients, from 2022, showed that supplementation of quercetin together with dasatinib slows cell proliferation and decelerates aging and the risk of age-related diseases. Participants took 500 mg of quercetin and 50 mg of dasatinib oral capsules on Monday, Tuesday, and Wednesday (3 days in a row) per month for the duration of 6 months. Dasatinib is a drug that's usually used to treat certain types of leukemia. A study in the Journal of the American Heart Association found that supplementation of 500 mg of quercetin daily significantly decreased blood pressure, especially among people with diabetes. Multiple studies have shown that quercetin acts on multiple targets of diabetes and regulates key signaling pathways, which improves the symptoms as well as the complications of type 2 diabetes. Several studies have found that supplementing with about 500 mg of quercetin per day helps lower levels of the inflammatory biomarker C-Reactive Protein (CRP), which is elevated in conditions like heart disease, rheumatoid arthritis, metabolic syndrome, and diabetes. A 2016 study on 50 women with rheumatoid arthritis found that 500 mg of quercetin daily for eight weeks significantly helped reduce morning stiffness and pain. Many studies have shown that quercetin offers neuroprotective benefits, due to its ability to defend the brain against oxidative stress and inflammation.
