The Claim
Some fitness enthusiasts claim that glycine supplementation can directly increase muscle mass and improve strength.
Origin
This misconception may arise from glycine's role as a component of creatine and collagen, which are involved in muscle and connective tissue health.
What Science Says
Current evidence does not support glycine as an effective supplement for muscle hypertrophy. While glycine is a precursor to creatine, which does enhance muscle mass and strength, glycine alone does not show significant effects in this regard. Meta-analyses of amino acid supplementation typically do not include glycine as a primary agent for muscle gain.
Verdict
False
