Glutamine

Glutamine is the most abundant amino acid in muscle tissue and blood plasma, and it plays a fundamental role in both muscle recovery and the immune system . Although it is considered a non-essential amino acid, during situations of prolonged physical stress , such as intense or high-frequency training, its demand exceeds the body's natural capacity to synthesize it, making it conditionally essential.

A decrease in glutamine levels can compromise protein synthesis , hinder recovery, and increase the feeling of muscle fatigue. Furthermore, it is a key energy source for lymphocytes , the cells responsible for the immune response, making it a valuable ally for maintaining defenses during demanding training or periods of high physical exertion.
