MusclePharm Core Series Glutamine is a unique blend of three types of Glutamine: L-Glutamine, Glutamine Peptides and Alanyl-l-glutamine. These aid in muscle growth, recovery time and digestion. Through three different yet highly effective blends of glutamine, your muscles, brain and digestive tract enjoy a tremendous range of benefits. You can also expect to support the absorption of protein, allowing for increased recovery and growth hormone facilitation. Glutamine promotes a healthy digestive system so your body absorbs the protein and nutrients it needs after sustained physical activity. It is also the main fuel for the intestinal tract and a more effective gut metabolism, structure, and function. The Glutamine Peptides in MusclePharmï¿½s unique blend increase protein synthesis and support the immune system, increasing your absorption and keeping you free of adverse side effects. The Alanyl-l-glutamine has excellent stability and solubility, supporting your intestinal and immune system health. Also, expect enhanced rehydration and endurance, which leaves you with more energy in the gym.
