Bests & Worsts Reviews from Amazon

It worked miraculously last year when I first took it, and I only had to take it for a few days and I was symptom free for weeks. However...this year for some odd reason it barely worked, and reading this other user’s review, it seems like I’m not the only suspecting of quercitin’s decline in quality...it’s really sad...I had to get actual allergy meds instead, quite disappointing considering how much I loved and trusted it
