L-Glutamine Supplements consist of pure L-Glutamine powder or capsules. L-Glutamine is an amino acid found in abundant amounts in muscle tissue. Heavy exercise depletes muscle stores of L-Glutamine, which leads to catabolism (muscle wasting). Using L-Glutamine is thought to decrease catabolism - particularly important when dieting to get lean.

Please note that many other supplements contain L-Glutamine as part of a protein blend.

Bodybuilding Supplements and Sports Supplements containing L-Glutamine include:

  • AST GL3 Glutamine;
  • AST GL3 Micronized L-Glutamine;
  • CNP Pro-Glutamine;

  • Sci-MX L-Glutamine.
