Description
L-Glutamine is a non-essential amino acid, meaning the human body can synthesize it on its own. However, under certain conditions such as intense exercise, injury, or illness, the body's demand for glutamine may exceed its production. L-Glutamine is the most abundant free amino acid in the human body and plays a crucial role in various bodily functions. It serves as a fuel for the gut and immune cells, supporting gut health and immune function. L-Glutamine is also involved in the synthesis of proteins, glutathione, and other amino acids. Additionally, it helps regulate blood sugar levels and supports muscle growth and recovery. L-Glutamine is found in various food sources, including meat, fish, eggs, dairy products, and some plant-based foods like beans and vegetables. However, supplementing with L-Glutamine can help ensure adequate intake, particularly for individuals with increased demands.
