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 felt effect immediately the same day when i drank n-a-g. I have some new terrible pain in my back (i am going to doctor to find out what it is ), until then one capsule twice a day decreases pain. I am very happy for buying this product. Please, click "yes" below, if this review was helpful.

This appears to be helping me with GI track issues. General health seems to also be improving. This may be playing a part.
