Glutamine is the single most abundant amino acid in your body making up over 20% of the circulating amino acids. It is involved in a variety of cellular functions including protein synthesis, gastrointestinal health, immune function, acid-base balance and of course muscle growth! Your muscle cells are responsible for synthesizing approximately 90% of the glutamine found in your body but much of this gets used up by your gastrointestinal system, kidneys and immune system. Therefore, your body is continually manufacturing glutamine to help offset this loss. Glutamine helps repair muscle, improve immunity, replenish liver glycogen, and it even plays a role in detoxifying your brain! But when it comes to muscle growth, Glutamine is one of the most important amino acids which is why it’s developed a cult-like following amongst bodybuilders and other athletes. Nutrabolics manufactured m|GLUTAMINE to deliver exactly 5000 milligrams of the purest form of glutamine commercially available. One serving os so concentrated that it contains more glutamine than 4 eggs, 4 oz. of beef or chicken! m|GLUTAMINE is also unflavoured so you can add it to fruit juice, protein shakes or your favorite sports drink. If you need to build muscle fast, then you need the help of m|GLUTAMINE.
