Hello, you don't need it. Glutamine is used for high-intensity anaerobic exercise, which is generally a group with a certain foundation for fitness for about 2 years. Its function is to prevent high-intensity exercise from causing a series of problems and causing muscle decomposition. To put it bluntly, it is a tonic used by fitness people whose muscles reach a certain level in order to prevent muscle decomposition. Junior trainers are unnecessary and ineffective. Buying some protein powder or creatine is a waste of money.
