Product Code: quercetin-phytosome-THR
Servings per Container: 60
Quantity per Container: 60 Veg Capsules
Widely distributed in the plant kingdom, quercetin is the most abundant of the flavonoid molecules. It is found in many foods, including apples, onions, teas, berries, vegetables of the cabbage family, seeds, and nuts.
The crucial advantage that is attributable to 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. In the case of Quercetin Phytosome, quercetin is combined with sunflower-sourced phosphatidylcholine to create a phytosome complex that easily crosses the gut barrier.
Quercetin has many beneficial effects on human health. Probably its most well-known mechanism of action involves stabilization of mast cell membranes, which helps to decrease the release of histamine. Other benefits include cardiovascular support and protection of the gastrointestinal tract. A number of quercetin's beneficial effects appear to be due to its antioxidant activity. Quercetin scavenges free radicals and inhibits the oxidation of LDL cholesterol. By itself, and when paired with vitamin C, quercetin reduces the incidence of oxidative damage to skin and nerves caused by glutathione depletion.
- Quercetin bound to sunflower-sourced phosphatidylcholine for enhanced absorption*

Amazing for people that suffer from allergies, would highly recommend
by Nick
I have long suffered from allergies seasonally. Every year like clockwork September through November, and April through May, I get intense headaches, runny nose, scratchy throat, and many other symptoms associated with allergies. Sometimes my allergies are so bad that I have sneezing fits wher I sneeze for five minutes nonstop. I have always relied on over-the-counter medication‘s like Claritin and Nasonex to help me. That is until I found this. This pill works so well, and I like that I don’t have to worry about the fact that it’s a pharmaceutically, manufactured chemical, but a naturally occurring compound found in plants. By this medicine, if you suffer from allergies, I know it will help you.

Effective, trusted, supplement. Good quality product.
by Suzy Q
I trust Thorne products. Quercetin helps me with food allergies. If taken at night, I don't wake up congested. Zinc is also good for food allergies. I take both. I'm doing much better since being on these products.

No More Sneezing & Sniffly Nose Allergy Issues
by trees
Claritin and Flonase were not very effective. I researched Quercetin & learned a wealth of information including from NIH. And I learned that it doesn’t work for everyone. I took a chance & after less than 12 hours after my first 250 mg Quercetin, no more sneezing & sniffling nose issues. I take 250mg morning & 250mg evening.

Quercetin for Energy and Inflammation
by CuseSweetnessUSA
I’ve been a fan of quercetin for years and I know it helps me with increased energy and endurance. I had been drinking FRS for years and I love it, but they go in and out of stock frequently and shipping is expensive. Taking it daily, quercetin gave me the energy boost that I needed after long days at work to get my work out done in the evening. I stopped taking FRS for a while and noticed a difference (most notably a weight gain) so I’m glad that I found this supplement by Thorne as my new alternative. Thorne is a reputable company, so I trust the quality of the supplement.
I recommend googling quercetin to see if it’s right for you. Dr Axe is a fan of it as it fights inflammation and free radicals. Inflammation is the root cause of a lot of diseases, so quercetin is a minimal investment with potentially great returns.

Best quercetin on the market, though I wish it were cheaper!
by Jodi
I take 500mg of quercetin twice a day, so I switch between this product and a regular dihydrate version with no phytosome, for cost reasons. I bought this one because studies show it is more bioavailable than regular quercetin. I find it has helped my reactions a lot, and especially seasonal issues with pollen and other allergies. I don't leave home without it now.
