Healthwise® L-Glutamine is a 100% pure pharmaceutical grade amino acid powder. Glutamine is the most abundant amino acid in the bloodstream. It is considered a 'conditionally essential amino acid' because it can be manufactured in the body. However under extreme physical stress such as injuries, burns, infections, trauma or surgical procedures, the demand for glutamine exceeds the body's ability to synthesize it. Did you know? After surgery, nitrogen is vital to repair wounds and about 1/3 of nitrogen used by the body for this purpose relies on adequate glutamine stores.
