I have generally not been a fan of over the counter supplements because they are not regulated. I have watched & tried to research some antibiotics promotions. I believe as a Crohn sufferer we need nutrients. My dr hasn't taken a strong opinion. Doesn't it stand to reason with constant battles of symptoms or flares that it would be a good idea. Always felt lost on this issue. Do others supplement? How do you know you are getting what is in pills? To me, this is an on going and pretty big issue. What to believe, what to do?
