College football teams use pickel juice for fast relief from cramping. There is research to back them up, it It works faster than it can get digested. I know because I get them from time to time myself and I used to just have to wait them out. I drink about a half cup and wait about five minutes, I tried using it proactively but it seems like my body was building up a tolerance, so I just use it as needed and very rarely to prevent them from starting up.
