Hi, I use Epsom Salts from anywhere I can get it. It's very cheap. Most people would recommend that you get it from the chemist, for human consumption. However as it's mostly produced by the same company, I don't think it's any different. Yes it does tast horrid but you get used to it. People add fruit juice to disguise the tast. Good luck on your quest for health. Love and Light, Deotima.
