Glutamine 1000mg- Essential Amino Acid for Muscle Form
L-Glutamine is a flavorless, easy-mixing powder and an extremely versatile free form amino acid formula. It is the most abundant, naturally occurring amino acid in muscle tissue, but it can be depleted during prolonged training. Supplementing with L-Glutamine replenishes depleted stores, to help build new lean muscle and protect hard-earned gains by supporting protein synthesis. L-Glutamine also supports acid-base homeostasis. L-Glutamine supports post-workout muscle energy repletion, volumization, and repair. This "conditionally essential" amino acid functions as a critical factor in muscle form and function.† Supports Muscle Cell Volumization And Muscle Development Taking L-Glutamine supplements will help you improve exercise performance and gain muscles. The supplement also hydrates your body cells which are critical for repair and growth. Replenishes Depleted Glutamine Levels When one is stressed, ill, or injured, the L-Glutamine levels will go down, causing your body to look for the amino acid in your muscles to fill the gap. Glutamine supplements can support faster recovery for several ailments.
