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 tried glucosamine sulfate with no effect but NAG was able to cut my neck and intestine problems by 60%.

Since using N-A-G from Jarrow Formulas that nagging joint and coccyx pain I had been experiencing for years has virtually vanished

I use NAG to boost my mood as well as my joint healthy. I have a compromised digestive system and my digestive lining apparently does not make much acetyl. NAG supplies the acetyl and boost my mood better than any form of choline I have tried.

I read about NAG in the Lancet and found this product. This is the acetyl form of glucosamine that isn't the same as the regular glucosamine that everyone buys for joint pain. It has been proven to help the intestinal tract but also effective for joints and now a new study in mice found it helpful for MS. I was having a long bout (exacerbation) of M.S. I have been feeling absolutely wonderful since taking this product. I haven't felt better in yrs.!

acetylated forms of many biological substances are very often the superior forms - in terms of heightened stability, absorption through the intestine, increased solubility in the plasma, and better transport across the Blood-Brain-Barrier. - - - - - - - - - Month ago a friend of mine recommended me this product to treat IBS caused by mercury. 3 grams a day really work because I feel the same improvement as if taking 10 grams glutamine - the main precursor of NAG and an essential building block of intestinal wall. - - - - - - - Like the fact Jarrows use only one filler ingredient.

This glucosamine product assist my system in two ways. I have experienced irritable bowel system in the pass and it keeps it in check. Also without taking this form of glucosamine, my back and muscle pain would be much worst. As long as I am taking it I can keep any discomfort to a minimum. Thanks iherb for continue to have this product for my benefit.

Have been using the product for a few years and as a result my back aches have nearly disappeared. The product also appears to be gentle on my stomach.

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.
