N-acetyl-d-glucosamine (nag)

N-acetyl D-glucosamine (also known as NAG) is an amino sugar which is an essential component of body tissue.

This nutrient is very important in reparing the superficial layers of the gut mucosa - the layers which come in direct contact with the intestinal contents.

Like vitamin C, NAG is extremely important in the renewal of all structures which rely on collagen.
