These were exactly what I needed after 5 months of torture
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.

Can’t go wrong with Thorne.
It’s hard to say, cause I’m taking so many supplements, but anything by Thorne is top quality.
