You may want to find a product that combines both L-glutamine and glutamine peptides. This would help ensure good uptake, absorption, and stability in the body.
Like L-glutamine, glutamine peptides are credited with helping in the recovery of trauma, surgical and other critically ill patients. It is also believed that they may have immunomodulatory, anticatabolic/anabolic, gut mucosal barrier-protective and antioxidant actions.
In one recent, double-blind, randomized, controlled study, patients who had undergone major abdominal surgery, had their hospital stay significantly reduced, when they were given glutamine peptides. Mean cumulative nitrogen balance was significantly better in these patients, as was immune function, as measured by lymphocyte counts and generation of cysteinyl leukotrienes by polymorphonuclear neutrophils, a measure of neutrophil function.
The dosage for someone who has surgical trauma is typically 12 grams (given as L-glutamine) daily. It is about 25 grams (given as L-glutamine) daily for people with severe trauma and infections. For those who are using it orally as a supplement for fitness or sports purposes, it is recommended to use 1.5 to 4.5 grams (as L-glutamine) daily.
There are no known reports of overdose with glutamine peptides. There have been rare reports of people having constipation and bloating with high doses of glutamine peptides. They are contraindicated in those hypersensitive to any component of a glutamine peptide-containing product.
People with renal and liver failure should be very cautious in the use of glutamine peptide supplements. If you are pregnant or nursing you should avoid the use of oral glutamine peptide supplements unless otherwise directed by your professional healthcare provider.
