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 a natural aid for endurance and recovery, while aging individuals find it beneficial as a daily supplement for total body defense and comfort. New Maximum Strength Quercetin from Swanson Ultra features 800mg of high-purity quercetin anhydrous in every capsule for reliable dietary support.
