This stuff is amazing! My husband suffers from terrible leg cramps some nights. He would be up and down several times a night in terrible pain. No doctor could ever find a solution. I decided to search online and found this remedy. It is truly a miracle. The cramps stop in seconds and do not come back for the remainder of the night. I have stocked up anh iHerb has the very best prices. I read the reviews, I believed and trusted, and it was an excellent choice!
