A Integrated doctor recommended that I try Culturelle, Lactobacillus GG, after I mentioned the pain issue. I forgot to mention that I'm having major problems with constipation. I cant believe I never raised this issue!!The company making probiotic claims it has been tried and tested for Diarrhea and client testomany has proven that it helps with Diarrhea, and ther hasnt been much testing on people with Consitpation.I raised my concern with the doctor and he claims the opposite. I am so confused - instictively I trust the company however feedback from you guys would be the most helpful and trustworthy to me.Please let me know if anyone knows whether this probiotic is more for C or D, or either and what experience you've had.Thanks.
