I was taking the L-glutamine/N-acetyl D-glucosamine on and off for awhile. One bottle of Intestamine is supposed to last like a month, but it took me like 8 months to finish two bottles because I didn't take it consistenly enough. I just recently started my third bottle. I can't say exactly if it helped because I was trying loads of stuff at the same time. I probably should have tried everything one at a time to see if it helped, but I was so desparate to "cure" this problem that I didn't care - sooner was better for me. I do feel like it helped heal my intestinal lining though. If I had an upset stomach and took it, it would help. But as for whether or not it cut down my B.O., I can't say for sure. But it's possible. I'm curious who this lady is that you speak of who cured her B.O. with these two supplements. Were these the only two supplements she took? Also, how much did she take? I'm guessing it was more than a few grams per day. Intestamine is 5 grams (5,000 mg) per serving (twice a day), which seems to be a lot when you compare it to how much say bodybuilders take. But they, of course, take it for a different reason.
