Glutamine Peptides

Glutamine peptides are short chains of amino acids, specifically glutamine. They are typically produced by breaking down larger protein sources, such as whey or plant proteins, through enzymatic or acid hydrolysis. This process yields smaller, more easily digestible protein fragments.

Glutamine peptides are primarily used in sports nutrition products like protein powders and bars, and in some specialised dietary foods. They are added to provide a source of protein and amino acids, which are believed to support muscle recovery and growth after exercise. Their smaller size may also offer faster absorption compared to intact proteins.

Glutamine peptides are not typically classified as food additives in the UK and therefore do not have an E-number or require authorisation on the Register of Food Additive Authorisations. Glutamine is an amino acid naturally present in the body and in many protein-rich foods. The European Food Safety Authority (EFSA) has evaluated glutamine in the context of its role as a nutrient. Evidence regarding specific health benefits from consuming glutamine peptides, particularly in relation to muscle recovery, is mixed and often studied in the context of intense athletic training.
