S.O.
I would never take all those supplements every day. They could build up in your body and cause you to become sick or worse.
Have you been tested for Celiac? I was diagnosed with IBS over 20 years ago and the symtoms just kept getting worse. Finally 2 years ago a doctor suggested I may have Celiac. It is very common to be diagnosed with IBS when you actually have celiac. It is amazing how much better I feel now that I am on a glutten free diet.
