Glutamine is a non-essential amino acid that becomes conditionally essential during times of physical stress, such as intense exercise. It plays a central role in nitrogen transport, immune system function, and muscle recovery.
Athletes and fitness enthusiasts often supplement with glutamine to promote muscle repair, reduce exercise-induced soreness, and support gut health. It is particularly valued during periods of intense training, when the body’s natural glutamine reserves may be depleted.
In addition to muscle recovery, glutamine also supports the integrity of the intestinal lining and is involved in glycogen synthesis—making it a multi-functional amino acid for physically active individuals.
Synonyms:
L-glutamine
Benefits:
- Supports muscle recovery and reduces soreness
- Helps maintain immune system health
- Contributes to gut health and digestive support
- Aids in nitrogen balance and protein metabolism
Sources:
- Found in high-protein foods like beef, chicken, fish, eggs, dairy
- Also synthesized in the body and available in supplement form
Observations:
Commonly used in powder or capsule form post-workout. Typically well tolerated; excessive doses may cause mild gastrointestinal upset. Useful during cutting phases or high-volume training.
