For anyone needing L-glutamine, it's currently on sale at 50% off. I just bought 2 x 1000 grams.
Sorry, I don't know how the glutamine is affecting you...
I used to take 15grams a day while flaring, now I am down to 5g per day.
I agree with Gary, if you can afford it, the VSL #3DS would be well worth it.
