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.

I came across this one day by accident while surfing around the Iherb website. I suffer from a lot of food allergies, digestion problems, and arthritis. After a particularly bad weekend - stomach was upset, arthitis was aching - I started taking this supplement. My stomach felt immediately soothed and my arthritis pain was gone. I can't believe my arthitis is not aching anymore and my digestion problems are practially gone. I don't plan on ever stopping this supplement. I am not sure why I never heard of this before.

I can't believe I have gone this many years with Crohn's disease and have never heard of this product before. It really does help to heal the gut and keep things in check for me. I will definitely keep it on hand.

This product seems to help my irritable bowels and I believe it's helping my dry eyes.

This product seems to be underrated as I don't hear very much about it. I started taking these and noticed a huge difference in my GI pain and inflammation. I also noticed improvement with my sinus issues. So glad I found this product. **edit** 9/29/13 I bought this product once again when I developed bad anxiety issues. It helps to take the edge off anxiety and keeps me from panic attack level. Not sure of the mechanism, but very helpful for anxiety. Google N-A-G and anxiety for others with same effect.

I bought it for a lower intestine problem and within 2 weeks it began to take effect. Surprisingly, I believe it may also be helping my hip arthritis. I seem to be able to move with more ease these last few months. After reading the reviews, I also purchased a bottle for my daughter who has a lower back problem and for my elderly mother who has a chronic gas problem. Without a doubt, my mother's situation has improved. Not yet certain if my daughter has gotten relief for her backache.

Wish I could give higher than a 5 as this made a big difference for me. With my fiber cereals, this has completely solved my ibs problems.

My digestion/elimination was doing fine till I ran out of this stuff. Now, it's doing great again! Thank you for having a great product at a great price.
