In the last two decades, L-Glutamine has become an integral product in virtually any and every bodybuilder’s arsenal to insure proper immune function, possibly reducing skeletal muscle recovery time from heavy exercise and increasing endurance. Over 130 scientific studies have been conducted at universities and independent testing sites around the world clearly testifying to the safety and usefulness of this ingredient. Both The American College of Sports Medicine (ACSM) and The Journal of The International Society of Sports Nutrition (JISSN) have sponsored presentations and published scholarly research regarding the use of L-Glutamine. Athletes as well as many university professors, sports medicine physicians and sports trainers agree that L-Glutamine is a critically important and useful amino acid and is needed to insure optimal health and a functional immune system.
