During the recovery period, it favours the storage of muscle glycogen and can stimulate the secretion of GH. Glutamine is considered as being able to fight the overtraining syndrome (chronic fatigue, loss in weight, loss of appetite, minor infections, nausea, depression) and to play the role of energy support in quickly multiplying cells such as lymphocytes and macrophages, contributing to support the immune system. In the central nervous system, it is converted into glutamate that is the most important and widespread central excitatory neurotransmitter. Just as important is the Glutamine ability to detoxify and regulate the blood and urine pH with a buffer effect.
Glutamine intervenes in the formation of glutathione that is the most powerful antioxidant our body produces. This consists of glycine, cysteine and glutamic acid, derived indeed from Glutamine. Apart from these specific functions, Glutamine plays a role transporting nitrogen between cells, therefore helping the organic and metabolic functions that are accelerated during physical exercise or pathological stress. Finally, Glutamine is involved also in collagen synthesis that preserves particularly stressed tissues and promotes the recovery of the traumatized ones.
