  • Highly pure quercetin for maximum absorption potential



  • Unique antioxidant with key benefits for heart health, immune system and more



  • Also a favorite among athletes for its endurance and recovery support


Quercetin is in high demand today among active individuals looking to boost energy and counter the physical stress of modern life. 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 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 800 mg of high-purity quercetin anhydrous in every capsule for reliable dietary support.

Maximum Strength Quercetin 5 5 1 2
A difficult-to-pronounce pill with easy benefits! Quercetin is a supplement that I miss when I run out. This helps assist me with allergen control. There are many health benefits to this, and I have never experienced any noticeable side-effects from taking quercetin for years. Now this is high-potency quercetin though, so keep that in-mind. I am just starting out on this one, but I'm not too worried. One of the reasons I got this one is because I like many of the Swansons lines, because of quality and price, and the amount you get in a product; and this one at the time I got it had a buy-one-get-one-free promotion, and the pills were very potent, which is what I wanted. I also like the fact that the quercetin comes in a light-protective brown plastic bottle. Note that these pills are quite big, so if you have a hard time swallowing pills, then I would suggest either getting a smaller dosage, or opening a pill, and then mixing the quercetin powder into fruit juice with a teaspoon, then just drinking it. Overall, I am thrilled that Swansons has come out with this. I also appreciate the extra bottle for free. If you need or want a lot of quercetin at a high potency with a competitive price, here is an option for you. August 7, 2014
