DeepSummary
In this episode of the Ask Dr. Hazel podcast, a listener asked about the claims surrounding the amino acid L-glutamine and its supposed benefits for gut health and exercise recovery. Dr. Hazel Wallace explained that L-glutamine is a conditionally essential amino acid found in high-protein foods, meaning the body can produce it under normal circumstances but may need extra during times of stress or illness.
Dr. Wallace mentioned that while there is some emerging evidence for the use of L-glutamine in supporting gut barrier function in conditions like IBD and celiac disease, supplementation is unlikely to be beneficial for healthy individuals without any gut issues. She emphasized the importance of understanding the root cause of any gut problems before considering supplements.
Regarding the claims of L-glutamine aiding exercise recovery and muscle protein synthesis, Dr. Wallace stated that the evidence is mixed, especially for otherwise healthy people. She expressed interest in the supplement but stressed the need for more research before endorsing its use for this purpose.
