                                While glutamine is a critical amino acid for many bodily functions, excessive levels can contribute to significant health problems, especially in individuals with pre-existing conditions. In patients with severe liver disease, for example, high glutamine can worsen hepatic encephalopathy by increasing ammonia and causing brain swelling.
