Muscle Aches

[Star]

A friend of mine over 50 used to take this supplement after workouts to keep his muscles from hurting. He said it had something to do with electrolytes. Anyway he can't remember the name of it and since he started working out again would like to find it. Anyone know the name of this stuff. Thanks for your help!!!!
