This little gem belongs to a group of plant compounds called flavonoids. It is found in fruits such as grapes, blueberries, strawberries, cherries, apples, grapefruit, cranberries, raspberries and blackberries; vegetables including onions, peppers and broccoli; and beverages like coffee, green tea and red wine.
Quercetin is one of the most abundant antioxidants, and its role is to fight free radical damage. Free radicals can damage our cells, which in turn can promote inflammation. Hippocrates is often quoted as saying, “All disease begins in the gut,” and this is closely linked to inflammation.
In an eight-week study, 50 women with rheumatoid arthritis took 500 mg of quercetin daily. They experienced significantly reduced early morning stiffness, morning pain and after-activity pain. Quercetin has also been found to help protect against degenerative brain disorders such as Alzheimer’s disease and dementia.
Quercetin offers cardiovascular benefits as well. It may help lower blood pressure and reduce cholesterol levels by improving endothelial function. This makes it a promising candidate for supporting heart health and helping prevent cardiovascular disease.
In addition, studies have found that quercetin exhibits anti-cancer properties by inhibiting cell proliferation and inducing apoptosis — a type of programmed cell death in which a cell destroys itself when it threatens the survival of its host.
Many studies continue to explore the benefits of this powerful flavonoid. Research has shown:
Neuroprotective properties
Inhibition of tumor growth
Liver protection
- Prevention support for macular degeneration and cataracts
- Quercetin has also demonstrated anti:
- Bacterial activity
- Viral activity
- Obesity-related effects
- Diabetic complications
- Hypertensive conditions
- Allergic responses
- Asthmatic responses
This is not an exhaustive list of its benefits, but they are certainly worth noting. Look up foods and herbs that contain quercetin and begin incorporating them into your diet. Check your multivitamin to see whether it contains this antioxidant and in what quantity. A common supplemental target is 500 mg daily.
Quercetin is also available in supplement form; Solaray is one brand often recommended.
Disclaimer: If you are currently taking medication for any of the conditions mentioned above, consult your physician and perform your due diligence regarding potential interactions before beginning supplementation.
