Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Glutamine is a non-essential amino acid that is abundant in skeletal muscle and plays a role in nitrogen transport, immune function, and intestinal health. Its use as a supplement to support the muscles body system is based on its role in protein synthesis and muscle recovery. Scientific studies have shown that after intense or prolonged exercise, glutamine levels in the blood can decrease, which led to the hypothesis that supplementation might aid muscle recovery and reduce muscle soreness.

However, the evidence supporting glutamine supplementation for muscle growth, strength, or recovery in healthy individuals is limited and mixed. Several clinical trials and meta-analyses have found that glutamine supplementation does not significantly enhance muscle protein synthesis, muscle mass, or exercise performance compared to placebo in well-nourished adults. There is some evidence that glutamine may help reduce muscle soreness and improve recovery in certain populations, such as those undergoing prolonged endurance events or individuals with muscle-wasting conditions, but these effects are not robust or consistent across studies.

Overall, while glutamine is scientifically recognized as important for muscle metabolism, current research does not strongly support its supplementation for muscle health in healthy, active people. Its use is therefore rated low on the evidence scale for supporting the muscles body system in this context.
