L-Glutamine: Prevents muscle breakdown • Major source of energy for the entire body • Builds, repairs, and maintains muscle tissue • Essential ingredient in numerous brain functions which are vital to brain metabolism • Performs a major role in DNA synthesis and supports the immune system What is L-Glutamine and what does it do? L-Glutamine is the most abundant amino acid in muscle tissue and plays a key role in many bodily functions. During stressful situations (i.e. heavy resistive weight training) the body can lose a large amount of glutamine. A loss of glutamine during exercise may be a signal for protein catabolism (muscle breakdown). Glutamine supplementation has been shown to prevent the loss of body mass through the positive role glutamine plays in protein synthesis and its action as a potent muscle growing agent. When muscle glutamine levels are restored and in a positive nitrogen balance muscle synthesis can return to a normal rate. Glutamine also has actions on glucose metabolism and the regulation of gluconeogenesis. Glutamine converts to glucose without changes in insulin or glucagen, the hormones that regulate blood sugar. During dieting, and times of carbohydrate depletion, glutamine can exert positive effects on the amount of body fat burned. Why take L-Glutamine? Glutamine is the most important component of muscle protein, and helps repair and build muscle. Glutamine has been linked to protein synthesis. It prevents your muscle from being catabolised (eaten up) in order to provide Glutamine for other cells in the body. Glutamine helps maintain cell volume and hydration, speeding up wound and burn healing and recovery. Glutamine benefits you by replenishing declining Glutamine levels during intense workouts. Research has shown Glutamine can help you produce growth hormone levels. A study has shown 2 grams of L-Glutamine increased growth hormones by over Glutamine may serve to boost your immune system. For bodybuilders, this is important since heavy workouts tend to greatly deplete Glutamine levels. (Glutamine is a primary energy source for your immune system.) Glutamine is one of the most important nutrients for your intestines. It has the ability to 'repair a leaky gut' by maintaining the structural integrity of the bowels. It can also cure ulcers. Studies have found that 1.6 grams of Glutamine a day had a 92% cure rate in 4 weeks.
