Dietary Supplement. Pure HPLC tested pharmaceutical grade. Enhances Muscle Nitrogen; Restores Muscle Glycogen; Increases muscle cell volume. Boosts circulating growth hormone levels by over 430%! Glutamine represents over 63% of the amino acid content in the amino acid pool of muscle tissue. Intense training and exercise put greater demands on your body's need for Glutamine, making it a conditionally essential amino acid. Micronized GL3 L-Glutamine represents a leap forward in Glutamine supplementation. GL3 uses a state-of-the-art Particle Micronization Technology (PMT). Each tiny particle of GL3 is 20 times smaller than regular Glutamine powder. This allows for ultra-fast absorption and utilization. Glutamine is the most common amino acid in the body and is key to the metabolism and maintenance of muscle tissue. Glutamine is also the highest concentrated amino acid in the muscle cell and acts as a primary shuttle for nitrogen from the blood stream to inside the muscle cell. Glutamine has a multifaceted role in human nutrition and is essential for the support of muscle tissue and immune function.
