Our bodies naturally produce glutamine, a nonessential amino acid that becomes a conditionally essential amino acid during stress, injury, or sickness when the body’s glutamine levels decrease. As the most abundant amino acid in the human body, glutamine is vital for supporting the immune system and promoting gut health.
Compared to other amino acids, glutamine is also the most versatile, used in clinical and sports nutrition for its immunomodulatory functions. Below are the best L-glutamine supplements for promoting the many benefits of glutamine to support your health and fitness goals, like gaining muscle and reducing recovery time!
