I've suffered from IBS for over a year and tried various remedies without success. I read an article on the internet that stated taking L-Lysine tablets could help cure IBS. I started taking one tablet (500mg) each day on an empty stomach. I noticed an improvement within a week and now two weeks later all symptoms of IBS have disappeared. I mentioned this to the owner at my local health store but she was adamant that L-Lysine would not ease IBS symptoms. I feel totally free of all the symptoms that I have suffered with over the past year so would suggest to any IBS suffers just to try L-Lysine for a month in hope that it works for you. Good luck.
