How does l-glutamine affect insomnia and can it be used as a remedy for improving sleep quality?

L-glutamine is an amino acid that may help improve sleep quality by promoting relaxation and reducing stress. It can also support the production of GABA, a neurotransmitter that helps regulate sleep. While more research is needed, some studies suggest that l-glutamine may be beneficial for insomnia. However, it is important to consult with a healthcare provider before using it as a remedy for sleep issues.
