Rated 5 out of 5 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.

Rated 5 out of 5 by Vitamin Pro 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!

Rated 4 out of 5 by LDJ 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.

Rated 5 out of 5 by Kettlebell Instructor 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.

Offsets flush from flush niacin and as such, is an alternative to common, over-the-counter tablets. A useful antihistamine as well.
