N-Acetyl Glucosamine anyone? in Post Diagnosis, Recovery & Treatment of Celiac Disease Posted August 20, 2018 · Report to Admin About four years ago I started a topic about N-Acetyl Glucosamine. It is supposed to be able to bind to gluten lectins and escort them from your body, before they damage your intestines and joints. I did try a bottle and had ok results, but didn't keep with it. Since then my gluten sensitivity has gotten worse, and so have my knees, to the point where I had to get a cortisone shot for the pain. I am going to try the N.A.G. again, and stay on it longer this time. Any thoughts appreciated!
