I'm a qualified ketogenic nutritionist and can confirm that N-Acetyl Glucosamine is one of the most important bioactive supplements to be taken for intestinal health. Simply put, it "repairs" the intestinal lining that has been damaged by years of stress, antibiotics & spicy, acidic food. NAG heals the intestinal lining and makes way for the development of good bacteria -- an essential part of colon health.

First of all Jarrow Products are Excellent.
This product , felt some of the capsules might be leaking white powder...since there was a mild white residue on my hands...makes me wonder
