Blurry vision issue
It was good, but I experienced blurry vision and an itch as side effects of Quercetin. One week after I started taking it, I had blurry vision in my right eye, which resolved once I ceased taking it. The itch also vanished when I stopped. Be cautious as this site is often just an echo chamber regarding reviews; read the fine print first. This product may not be suitable for everyone.
