Quercetin – Nature’s Antioxidant Flavonoid

Quercetin is a naturally occurring plant flavonoid found in apples, onions, berries, and leafy greens, prized for its powerful antioxidant and anti-inflammatory effects. By neutralizing free radicals and reducing oxidative stress, quercetin supports immune balance, cardiovascular function, and overall cellular health. Research suggests it may help regulate immune responses, reduce seasonal allergy symptoms by stabilizing histamine release, and lower blood pressure while improving vascular function (Nutrients, 2016; British Journal of Nutrition, 2016). Its anti-inflammatory and antioxidant actions are also linked to a reduced risk of chronic disease, while studies show that supplementation may enhance exercise recovery and endurance by reducing fatigue and oxidative damage (Nutrients, 2020; Med Sci Sports Exerc., 2009). Common supplemental doses range from 500–1,000 mg daily, often combined with vitamin C or bromelain for better absorption. Generally safe and well tolerated, quercetin can occasionally cause mild digestive upset and may interact with certain medications, so professional guidance is advised. With benefits spanning immunity, heart health, inflammation control, and performance, quercetin is a versatile nutrient that strengthens the body’s defenses and promotes long-term wellness.
