                                According to manufacturers and lab studies, dry L-glutamine powder is highly stable and can last for several years when stored properly. The shelf life is primarily determined by environmental factors, with moisture and temperature being the biggest threats to its potency. Protecting your supplement from these elements is key to preserving its quality over time.
