I got cat's claw as a stand-in for quercetin, hoping it would save some money because quercetin has benefitted me very well, but it can be expensive; so after researching cat's claw from some of my friends' recommendations on it, I thought I would give this a try.Well, after taking it a while, it was not as effective as quercetin for me as I had hoped, but cat's claw has other benefits that quercetin does not; exactly what I wish I could specifically tell you.... buuuuuut, due to governmental regulations on posting medical and disease claims online here,.... I cannot. :( What I CAN tell you is that information on the specific health benefits of both quercetin and cat's claw can be found online! :)Overall, I am happy with this purchase, because you get so much for your money, and even though cat's claw was not as effective as quercetin for what I had hoped; the OTHER benefits from cat's claw seemed just fine! :D
