Glutamine as a supplement is necessary for all biological processes in the human body. It is, in fact, the amino acid most present in the body for which its presence is necessary and, since it can vary following physical exercise, it is advisable to increase it with a supplement. Its role in maintaining the functionality of the immune system is also of fundamental importance. In the case of periods of severe stress or following trauma, it is advisable to resort to an external source of glutamine, such as BioTechUSA's Glutamine Zero 300 g.

Glutamine Zero by BioTechUSA is a food supplement suitable for combat sports athletes, those who train in the gym and all people who love good-tasting products without added fat. It is therefore a conditionally essential amino acid for athletes. Like all BioTech USA products, Glutamine Zero contains only safe and carefully selected ingredients.
