Boosted immunity
Great supplement. Allergies (nasal) vanished and no side effects. Helped me get over colds n coughs quicker. A super natural antihistamine and anti-inflammatory 🙌.

I don’t see the difference
I was taking this for my allergies and I don’t see any difference… I got on to antibiotics to reduce my allergies. But maybe a continued use of this supplement before the allergy season might help.

I'm a long-perm consumer of anti-depressant and anti-enxiety meds. This Thorne product appears to have have given me the boost that prescription meds cannot match. Such has been the positive change in the six weeks since I began taking it, I am reluctant to put it all down to Quercetin, but I haven't had a single bad day since starting them. Before this, I rarely had a good day. I will update in a few months.

My eustachian tubes have been full of velcro/rice krispie sounds for 5 months. It distorted sounds and the crackling noises every time I yawned or swallowed was so maddening. Learned there was an inflammation in the narsopharynx and now my eosinophils were chaotic and wouldn't calm and kept re-inflaming tissue on their own. I learned that quercetin inhibits the eosinophils so they can "realize" that there is nothing no longer wrong and go back to my normal range. After two weeks of use FINALLY the tube blockage dissipated and function nearly as they should since the eosinophils are finally chilling out and going back to normal numbers. I am nearly recovered and no longer hear crackling in my ears. BLESS THESE PILLS.

Another Quality product as with nearly all Thorne products! I trust Thorne for great research, excellent quality ingredients and a fair price for supplements that actually have proven health benefits.
