Glutamine is a conditionally essential amino acid that plays a crucial role in muscle recovery, immune function, and gut health. It is widely used by athletes, bodybuilders, and fitness enthusiasts to reduce muscle soreness, speed up recovery, and prevent muscle breakdown after intense workouts. Glutamine also supports gut integrity by fueling intestinal cells, making it beneficial for those with digestive issues or high physical stress. Additionally, it helps strengthen the immune system, especially during periods of intense training or illness. Found naturally in foods like beef, eggs, and dairy, glutamine supplements provide a convenient way to replenish levels and support overall health and performance.
