I just started it like 10 days or so ago. I am currently taking 4500 mg's daily.(1500 3 times) I started to take it because it was suggested that it would help my "gurgling" stomach and stomach noises. I started to notice last week that my digestion was a bit better. Nothing major but at least i went forward instead of backward. Still feel prett crappy otherwise though. Diet hasn't been the greatest and last week when it was the best the Glutamine did help. Does anyone know how long it takes for the Glutamine to really kick in?
