Product Parameters

M-glutamic acid, also known as "glutamic acid", can combine with blood ammonia to form harmless glutamine, reducing blood ammonia levels and thereby alleviating the symptoms of hepatic coma. In addition, it participates in cerebral protein metabolism and glucose metabolism, promotes oxidative processes, and improves the function of the central nervous system. It is used for the prevention and treatment of hepatic coma, the recovery period of hepatic coma, and severe hepatic insufficiency. Glutamic acid can also be used as an adjuvant therapy for the recovery period of coma caused by various reasons and neurological diseases (such as schizophrenia and epilepsy). The oral dosage is 2.5-5g each time, 4 times a day.
