Evidence supporting the use of: L-Alanyl-Glutamine
For the health condition: Athletic and Exercise Aids
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
L-Alanyl-Glutamine is a dipeptide composed of the amino acids L-alanine and L-glutamine. It is used in athletic and exercise aids primarily due to its ability to enhance glutamine stability and absorption. Glutamine is a conditionally essential amino acid that plays a key role in muscle protein synthesis, immune function, and intestinal health, all of which can be stressed by intense exercise.
Multiple studies have investigated L-Alanyl-Glutamine in the context of exercise. Clinical trials have shown that supplementation with this dipeptide can improve hydration status and endurance, especially when added to rehydration beverages. Research indicates that L-Alanyl-Glutamine is absorbed more efficiently than free glutamine, leading to increased plasma glutamine levels after ingestion. Some evidence suggests that it may reduce markers of muscle damage, decrease feelings of fatigue, and support immune function in athletes during periods of strenuous training or competition.
However, while the available research is promising, it is not yet robust or extensive. Most studies are small, short-term, or conducted on specific populations such as endurance athletes. There is moderate scientific validation for its use as an exercise aid, particularly for hydration and recovery, but more large-scale and long-term studies are needed to confirm its efficacy and define optimal dosages. Thus, the evidence rating is moderate.
