The Claim
Many fitness enthusiasts believe that supplementing with L-Glutamine can significantly increase muscle mass and strength. This belief stems from L-Glutamine's role as an amino acid, which is a building block of protein.
Origin
This myth likely originates from marketing campaigns by supplement companies and anecdotal evidence from bodybuilders in the fitness community.
What Science Says
Current research, including randomized controlled trials (RCTs), indicates that L-Glutamine supplementation does not have a significant effect on muscle growth in healthy adults engaged in resistance training. A meta-analysis of studies on amino acids and muscle hypertrophy showed no substantial benefits of L-Glutamine alone on muscle mass or strength.
Verdict
False
