Glutamine peptides are small protein structures that contain glutamine. Unlike free L-glutamine, the amino acid is still bound to other amino acids. They are usually extracted from plant proteins, such as wheat protein.

Free L-glutamine is a loose amino acid, directly available for absorption. In peptide form, the amino acid is part of a short chain. Some users choose peptide form because of the difference in stability or absorption characteristics.

The glutamine peptides in this product are derived from wheat, so the product may contain traces of gluten.

Glutamine is a conditionally essential amino acid.

Essential amino acids cannot be formed from other substances by animal organisms and must therefore be supplemented through nutrition or supplements. Non-essential amino acids can in principle be synthesized from other compounds within the organism. Conditionally essential amino acids usually fall into the second category, but may still be needed from external sources under certain circumstances, for example when demand is increased.
