  • Don't Be Fooled By Cheap Imitations - Not all Quercetin capsules are created equal! Many Quercetin supplements use plain Quercetin, Dihydrate or with Bromelain. These forms are not as easily absorbed. Peak Performance Quercetin Phytosome uses advanced phytosome technology, a process where quercetin is combined with sunflower-sourced phospholipids to create a bioavailable phytosome complex that is more easily absorbed in the stomach.*
  • Immune and Allergy Support - Quercetin  Phytosome is derived from Sophora japonica plant extract which is rich in flavonols (a subclass of flavonoids). It is an effective antioxidant and supports regular histamine levels, thereby helping to sustain a balanced immune and allergy response.*
  • Vegan Formulated - Manufactured without Soy, Milk, Egg, Shellfish, Corn, Wheat, Peanut, Gluten, Binders, Or Preservatives. Made under the highest quality GMP Regulations and USA Standards.
  • Happiness Guarantee - If you don’t absolutely LOVE this product... For ANY reason whatsoever, simply send us a message and we will be happy to offer you a fast, prompt refund. No Questions Asked! That’s how confident we are that you’ll love this product.

The Absolute Best!

Thank you so much for creating all the absolute best products with NO Synthetic garbage! This quercetin is helpful in so many ways. My allergies are gone. My skin looks amazing and I am truly satisfied with this product. I take your other supplements as well and they are all great. Huge difference from the other brands loaded with synthetics that do nothing for your body. You truly provide unadulterated supplements at a time when they are needed so much as our food supply is tainted so much with GMOs, lab created fillers and virtually no nutritional value. Thank you Peak Performance!

Will keep on using!

I used to get sick at least 1-2 times a year, but since using Quercetin in combination with other supplements, I have been totally healthy since December of 2019. Have never isolated from others or masked all thru the Covid years. It’s definitely working for me, and I will continue to use and recommend to others.

As seeen on
