Glutamine plays a key role in healthy immune function, protein metabolism, intestinal health, and may support the balance of nitrogen in your body. Vigorous workouts, high levels of stress, and poor nutrition can deplete our bodies' natural stores of Glutamine, a vitally important element in muscle growth. This can lead to your body tearing down muscle tissue to supply the rest of your system with Glutamine, reversing the effects of your training. It provides your system with the high-grade Glutamine it needs to spare precious muscle, increase protein synthesis, boost muscle glycogen storage (energy stores), and support healthy immune function. With all the work you do to build strong, hard muscle, don't let lagging Glutamine levels sabotage your results. Glutamine supplements may decrease muscle soreness and improve recovery after intense exercise. Glutamine supplements may improve health, decrease infections.
