Customer Ratings & Reviews

Rated 4.4 out of 5 by 12 reviewers.
Rated 5 out of 5 by I am thrilled I take 250 mcg in the morning and again in the evening April 19, 2015
Rated 4 out of 5 by Using Quercetin I have find that quercetin is the most effective product for relieving sinus congestion. December 7, 2013
Rated 5 out of 5 by Excellent Product I hardly do product reviews but could not resist this opportunity. I use this product to control the side effects of Niacin flushing. It is extremely effective. I take 1 capsule 30 minutes before meal, and Niacin immediately after meal. I noticed above 70% reduction in the intensity and duration of the flushing. On some days I hardly experience any flushing. Excellent product!! from Life Extension. November 11, 2013
Rated 5 out of 5 by I continue to buy this product I use the product to control niacin flushing May 28, 2013
Rated 5 out of 5 by Extraordinary Supplement Doing extensive research into plant-based ingredients, I found that quercetin is great for a variety of health concerns. I have a life-long problem with poor focus and concentration. Literally within a few hours of taking one capsule of Optimized Quercetin, my focus, concentration and mood were dramatically improved. Making sure it was not a lucky "shot in the dark", I took it again day after day with different foods & supplements...and the results have continued. I never want to be without this fantastic product. Way to go Life Extension! April 13, 2013
Rated 4 out of 5 by Quercetin + Miraforte works Most supplements don't do a thing for me, but this combo did. Bear in mind, I did get my blood tested before starting the combo, so it was targeted to me. I can do more chin ups, bench press, etc since starting. March 24, 2013
Rated 1 out of 5 by Optimized Quercetin Would never recommend this product. Very hard on the stomach. October 28, 2012
Rated 5 out of 5 by Great For Broad Spectrum Support I can't say that I notice any immediate effects, but I don't take supplements to relieve symtoms; I take supplements to provide support for optimal health. Based on the research of this product, that it comes from Life Extension and that it is available at such an affordable price, this will continue to be part of my supplementation plan. October 17, 2012
Rated 5 out of 5 by Optimized quercetin Helped reduce my allergy symptoms quite a bit. October 8, 2012
Rated 5 out of 5 by Excellent Product I use Optimized Quercetin for my seasonal discomforts. Its my alternative for allergy meds. I take 2-6 capsules daily. Love it! June 4, 2012
Rated 5 out of 5 by Multiple uses for Optimized Quercetin Offsets flush from flush niacin and as such, is an alternative to common, over-the-counter tablets. A useful antihistamine as well. April 2, 2012
