The powerful flavonoid nutrient is found in some foods, but only in small amounts. Supplements are the best way to get functional doses of quercetin. But did you know that quercetin comes in two forms? Common supplements supply quercetin dihydrate, which is only about 85% quercetin by weight. Quercetin anhydrous, by contrast, is 98% pure quercetin, making it the preferred form for high-quality, high-value supplementation. Over three decades of scientific research support quercetin’s benefits as a unique antioxidant with specific benefits for cardiovascular health, nervous system function, immune system health, joint comfort and physical performance. Fitness enthusiasts value quercetin as an aid for endurance and recovery, while aging individuals find it beneficial as a daily supplement for total body defense and comfort. Maximum Strength Quercetin from Swanson Ultra features 800 mg of high-purity quercetin anhydrous in every capsule for reliable dietary support.
