Role of Ingredient:

Remember that a proper concentration of Glutamine amino acid is necessary for the optimal performance of muscles in our body. Heavy training, exercise, or strenuous workout lower the average glutamine level in the body. [1, 2] Thus, L- glutamine supplementation regulates glutamine level and provide various health benefits, including protein synthesis. It aids the muscle recovery process, delays fatigue, relieves muscle soreness, and assists immune functions against various pathological agents. Moreover, Glutamine increases energy production and restores glycogen reservoirs that significantly benefit athletes. [1-3] Plus, it preserves gut mucosal integrity, improves healthy digestion, and strengthens the body’s resistance against infections and inflammation. [1, 4, 6] Besides, Glutamine supports neurotransmitters in the brain that promote nerve calmness, improve mood and help stressful conditions. [5] Thus, L-Glutamine intake enhances physical performance, stimulates muscle growth, potentiates workout productivity, and benefits overall health and wellness.
