Urban Muscle 100% Pure L-Glutamine - Naturally fermented. 
Urban Muscle uses only the absolute highest quality naturally fermented Glutamine to ensure the best possible results for recovery and/or lean muscle growth.
Glutamine is the most common amino acid found in your muscles - over 61% of skeletal muscle is Glutamine. Glutamine consists of 19% nitrogen, making it the primary transporter of nitrogen into your muscle cells.
During intense training, Glutamine levels are greatly depleted in your body, which decreases strength, stamina and recovery. It could take up to 6 days for Glutamine levels to return to normal - and Glutamine plays a key role in protein synthesis. Studies have shown that L-Glutamine supplementation can minimize breakdown of muscle and improve protein metabolism.
Glutamine plays key roles in protein metabolism, cell volumizing, and anti-catabolism. Glutamine also increases your ability to secrete Human Growth Hormone, which helps metabolize body fat and support new muscle growth. Glutamine\'s anti-catabolism ability prevents the breakdown of your muscles.
This is especially useful for people 'cutting down'. Especially during summer when you're trying to get rid of some body fat without losing any muscle. Glutamine is needed throughout your body for optimal performance. Your small intestines requires the most Glutamine in your body, and your immune system also needs Glutamine because Glutamine levels deplete during workouts, bodybuilders are more susceptible to illnesses - this is why L-Glutamine supplementation is so important, not necessarily to gain more muscle, but for the 'maintenance' effects of
 L-Glutamine.
