probiotics will take several months before it really adjusts/balances your immune system.
I use Primal Defense and I am so glad I started them. After about
a month, I noticed less diarrhea/ab. pain, and a better appetite.
I also take digestive enzymes, which enables me to eat more variety and a little bit of typical "no-no" chron's foods.
I did the maker's diet faithfully for several months, it helped a lot.
