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.

As my choice for NAG 750 came from the need to help my cartiledge recover from damage, I can 't possibly give a review now. It 'll take at least a couple of months to find out if this kind of Glucosamine works.

I haven't noticed any changes in my weight at all since taking these capsules. Dissapointed.
