Product Overview


  • Dietary Supplement
  • Now Containing Quercetin Phytosome (Quercetin Bound to Sunflower-Sourced Phosphatidylcholine)
  • A Potent, Well-Absorbed Antioxidant Formula
  • Provides Cardiovascular, Gastrointestinal, and Respiratory Support

Quercenase is a combination of quercetin phytosome and bromelain. Bromelain is a compound of proteolytic enzymes derived from the pineapple plant. Bromelain has protein-digesting and immune-enhancing properties. Bromelain also contains constituents that help maintain the body's normal inflammatory response, and may help the absorption of quercetin.

Quercetin stabilizes mast cells that store and release histamine. Quercetin appears to have many other beneficial effects on human health, including cardiovascular protection, as well as protection of the gastrointestinal tract. A number of quercetin's effects appear to be due to its antioxidant activity. Quercetin scavenges free radicals and inhibits oxidation of LDL cholesterol. By itself, and paired with vitamin C, quercetin can reduce the incidence of oxidative damage to skin and nerves caused by glutathione depletion.

The advantage of quercetin phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to phosphatidylcholine, a key component of cell membranes.

iHerb Customer Reviews

Greatly reduce allergic symptoms with Quercenase

Posted by 4839676326604278529 on May 02, 2017 | Verified Purchase

To mitigate the affects of seasonal allergies in Colorado, I recommend that my clients start Quercenase in the beginning of February and stop at the end of June. Quercenase reduces the accumulation of histamines that can lead to inflammation. Histamines helps each and every one of us combat allergies but, in quantity, they contribute to inflammation that impede the production of histamines when we need them most. Quercenase is a brilliant product that provides a formulary that makes it easy to digest and absorb. Quercenase is safe for children 8 and above. My clients rave about Quercenase, my husband who suffers greatly from allergies does so no more after taking Qurecenase for the last 3 years and I highly recommend this product as a professional.

Good for Allergies

Posted by Rena61 on Jul 19, 2015 | Verified Purchase

Here it is the beginning of April, I take one in the morning, and one before bed time to keep the allergies away. Edit: I notice my allergies went away when I started taking whole food vitamin C. I think this is an important key for me.
