Quercetin, a commonly occurring flavonoid and well-known antioxidant, has been shown to have significant anti-inflammatory effects in two recent studies.

In the first, researchers found that people who spent eight weeks consuming quercetin in conjunction with a high-fat diet experienced a decrease in signs of inflammation. (Stewart LK et al. Metabolism. July 2008; 57(Suppl. 1): S39-S46.)

Another study showed that supplementing with 1 mcg of quercetin for four weeks decreased inflammation markers by 23% and increased the antioxidant capacity in healthy volunteers. (Boots AW et al. Nutrition. Jul-Aug 2008; 24(7-8): 703-10.)

The Anti-Aging Bottom Line: Inflammation has been implicated in many different health problems ranging from arthritis to diabetes. These studies are in line with previous findings that supplementing with quercetin can have long-lasting antioxidant and immune boosting effects—both of which fight off inflammation.

QUICK TIP: Apples are a great source of quercetin. Studies have shown that eating apples can lower cholesterol, protect against cancer and heart disease, and improve lung function. Learn More
