A combination of quercetin phytosome and bromelain that provides support for allergy sufferers‚ as well as helping to reduce bruising and swelling

Quercenase combines bromelain‚ a compound of protein-digesting enzymes‚ with a highly absorbable form of quercetin. Quercetin stabilizes the body's mast cells‚ which store and release histamine.


Quercetin‚ one of the two primary ingredients in Quercenase‚ stabilizes the body's mast cells‚ which store and release histamine‚ so it supports individuals who suffer from allergies.

Quercetin appears to have many other beneficial effects on human health‚ including protection of the gastrointestinal tract and the cardiovascular system‚ where it scavenges free radicals and inhibits oxidation of LDL cholesterol.

Thorne's Quercenase combines quercetin phytosome (quercetin bound to sunflower-sourced phospholipids‚ which increases the body's ability to absorb the quercetin) and bromelain‚ a compound of protein-digesting enzymes derived from the pineapple plant. Bromelain also has immune-enhancing properties because it contains constituents that help maintain a healthy cytokine balance. Bromelain helps reduce bruising and swelling after an injury or surgery.

A number of quercetin's positive effects appear to be due to its antioxidant activity. By itself‚ and paired with vitamin C‚ quercetin can reduce the incidence of oxidative damage to the skin and nerves caused by the natural depletion of glutathione.

The advantage of quercetin phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to a phospholipid‚ which are key components of every cell membrane.

Bromelain‚ which is a mixture of proteolytic (protein-digesting) enzymes from the pineapple plant (Ananas comosus)‚ has been shown to promote healing and reduce temporary and minor swelling and bruising following an injury or a surgical procedure – including dental surgery. One study of patients with bone fractures found bromelain decreased swelling.

Bromelain exerts some of its positive effects because of its significant proteolytic activity. Plastic surgeons have shown interest in bromelain because of its ability to increase the resorption rate of hematomas following surgery.

      Me, my husband, and my 10 year old son suffer from sinus headaches, especially during the spring. Since taking Quercenase by Thorne Research all three of us have been headache free. We also take this with 1g of buffered vitamin C with each capsule, since it is also a natural antihistamine. I give my son 1/2g of C with each capsule. My son's overall level of itchiness has also greatly subsided. He suffers from elevated histamine due to MTHFR. Truly wonderful!

      Pros

      Prevents headaches.

      Cons

      Nothing at all.

      My blood work showed my uric acid levels were constantly high. After taking Quercenase at the recommendation of my ND for about 4 months my levels have started to drop. I use this along with a low-purine diet to help keep levels under control.

      Worked well for my allergies to mold. At first I needed to take a higher dosage but over time my body responds will to one or two a day when molds are high.

      Pros

      It works for my allergies and I dont have to buy drugs.

      Cons

      Can be much more expensive to use than over-the-counter drugs.

      If you have stubborn allergies Quercenase is for you! I found that taking 6-8 per day for 7-10 days works best and then taking 2 a day for maintenance during the allergy season works best!
