Have any of you taken any supplements that miraculously cured or dramatically improved your stuttering?

Have any of you taken any supplements that miraculously cured or dramatically improved your stuttering? Not pharmaceuticals or drugs, but supplements I've heard stories of the wonders of Omega-3s EPAS for some people, and others Thiamine B1. I've even heard stories about Psilocybin. Obviously these just go case by case for each individuals, but do you personally or know anybody who had a success story with any supplement?
