In the realm of sports nutrition, L-Glutamine, one of the 22 amino acids, takes centre stage, constituting up to 60% of the body’s free amino acid pool.
Although not deemed an essential amino acid for general health, it gains pivotal importance during intense training periods and for individuals contending with specific gastrointestinal disorders.
Recognised as a fundamental building block for both muscular and immune health, glutamine is indispensable for every muscle in the body.

L-Glutamine is a vital amino acid crucial for neural, intestinal, and immune functions in the body. While it’s naturally synthesized in our muscles and commonly found in our diet, during intense exercise, the body’s demand for glutamine may surpass its production, leading some to consider it ‘conditionally essential’.
Understanding its precise effects can be complex, but it is evident that L-glutamine plays a significant role, particularly in exercise and recovery from severe illnesses.
While meats, fish, and certain vegetables naturally contain varying levels of glutamine, athletes benefit from higher quantities.
Scientists have devised a fermentation process utilising glucose as a carbon source, ammonia as a nitrogen source, and a minimal amount of minerals and vitamins as growth factors.
This process yields glutamine on a larger scale, producing approximately 2000 metric tonnes annually, as reported by Isao Kusumoto in 2001.
Strength athletes and bodybuilders turn to glutamine for its anti-catabolic properties, which inhibit the breakdown of crucial muscle tissue.
This attribute proves vital for those requiring functional muscle mass, such as rugby players or bodybuilders preparing for competition while aiming to retain their hard-earned muscles.
One of the ways glutamine achieves this is by enhancing muscle cell hydration, a promoter of anabolic processes.
Glutamine also acts as fuel for the immune system. It’s long been established that a depletion of glutamine due to intense training or illness can adversely affect immune function.
A study published in the European Journal of Applied Physiology and Occupational Physiology demonstrated that athletes engaged in rigorous training, who supplemented with glutamine, experienced less frequent and less severe illness compared to those who did not (L. M. Castell et al, 1996).
The remarkable benefits of glutamine extend to its use in hospitals to counteract muscle loss in post-operative patients (F. Hammarqvist et al, 1989).
Studies showed that those who received glutamine supplements, such as glutamine powder, experienced less muscle mass loss compared to those who did not, even during periods of bed rest.
The optimal time to take L-glutamine can vary depending on your specific goals and lifestyle. Here are some common scenarios:
Remember, individual needs may vary, so it’s always best to consult with a healthcare professional or a registered dietitian who can provide personalised advice based on your unique circumstances and health goals.
