It's easy to distrust supplements when you think how much they promise and how little many deliver but I found this in a small chemist in London and used it to make my tummy less 'angry' after a short holiday and some very dodgy food. Anyway, believe me this works! It's not like a cork that just bungs you up, it works from within to soooooth! its magic...highly recommended indeed for all you sceptics out there!
