What are the benefits of L-Glutamine for gut health? What are its dietary sources?

L-Glutamine is an amino acid, serving as a building block for proteins and playing a key role in a range of bodily functions. Found in abundance in dietary sources like beef, poultry, fish, dairy and vegetables such as cabbage and spinach. L-Glutamine plays a crucial role in intestinal function and repair, it has been shown to activate protein kinases that facilitate intestinal stem cell differentiation and proliferation into enterocytes, goblet cells, and more. L-Glutamine increases gut enterocyte proliferation by maximizing the effects of growth factors like epidermal growth factor and insulin-like growth factor-I. These growth factors are responsible for influencing the DNA, RNA, protein synthesis, and replication of gut mucosal cells.
