NAG is a pre-biotic amoung other things. It is food for your gut flora to thrive on. For your gut flora to be healthy and repopulate, it needs food. This is how it helps your intestinal health. Take his on an empty stomach with your probiotic with plenty of water. I have found this product to work well for digestive health. FOS is another prebiotic that you can take to help with your gut flora. You can also eat Bananas, Leeks and Onions as they are all prebiotics. I have found it has helped with my digestive track function. This is also a precursor to Hylelonic(sp?) acid which is what helps to lubricates your joints. Many with arthritis take this. I don't have that condition so I cannot give a personal endoursement for that use, but I have read good things about it.

Seems fine so far. I didn't tolerate L-Glutamine powder, but I seem to be doing fine with this. (For GI health)

I've been taking NAG for several years now. If I run out (shame on me), I can tell within a matter of a few days. The relief from discomfort is huge when I DO take it.

I bought his product as I read in a small study it was great for healing the intestinal mucosa in crohns patients (they took about 3g a day). So I have been taking 6 tabs a day in 2 doses, and whilst I can't say yet whether it has had benefits there (I haven't been taking it long enough and I can't see inside!), it certainly has for my skin. I have a little bit of scarring on my face, and it seems to be improved. I will definitely keep taking it.

Great product and price. I am using this with aloe vera flakes and Thorne GI-Encap to heal leaky gut and stomach problems. Used together they are very effective. Great price.

This formula is hard to find. regular glucosamine is everywhere. Getting the acetyl version takes some hunting. I have read that you do need to be careful taking this with some medications. I have also read that it is water soluble and therefor it does not benefit you to take a larger dose at one time. I dont know if I have ever read any such info regarding regular formulations.
