Doctor’s Best Pure L-Glutamine Powder contains L-Glutamine, an amino acid that is a building block of protein. L-Glutamine is most commonly used to support muscle growth, skeletal muscles and athletic endurance. Supplementing with L-Glutamine allows the body the much-needed amino acids to increase muscle hydration. This is an essential process in the body that supports muscle recovery from high intensity workouts.*

L-G lutamine has an important role in maintaining muscle growth and health in both children and adults.* L-Glutamine is also the most abundant free amino acid in the body. It is synthesized mainly in the skeletal muscle, liver, and lungs and has an important role in energy production, being the major fuel source for the liver, the intestines, and immune system. L-Glutamine is an essential amino acid in critical states (stress, intense physical activities, injuries, illness) when the body’s need for glutamine exceeds its own capacity to produce sufficient amounts. Biological, pharmaceutical and safety aspects of L-Glutamine have been well studied. Based on research and many clinical studies, L-Glutamine has become widely known and used for its ergogenic capabilities, improving physical performance, stamina, and recovery after intense exercise among athletes. L-Glutamine supplements is also very popular among the general population and athletes for its role in immune health and exercise.*

Extended benefit - Helps Promote Muscle Growth and Athletic Performance* - L-Glutamine is considered as one of the most important amino acid involved as a building block of protein, promoting muscle growth. L-Glutamine is therefore very popular among athletes who undergo heavy workouts. Many studies highlighted the importance of L-Glutamine supplementation in stimulating anabolic functions such as protein synthesis, cell growth and differentiation, and inhibiting catabolic functions such as protein degradation. Individuals who engage in intense physical activities have an increased need of L-Glutamine to restore its levels to normal to avoid loss of muscle mass and preserve other biological functions. Therefore, L- Glutamine supplementation may promote muscle growth and support athletic performance.*

May Help With Recovery of Muscle Strength and Reduce Muscle Soreness After Physical Exercise* - Any intense exercise can lead to muscle damage. Various clinical studies showed the importance of L-Glutamine supplementation on the recovery of muscle strength after heavy workouts. Being the central free amino acid in the body, L-Glutamine is vital to muscle function. Research has demonstrated L-Glutamine plasma level could greatly be reduced during post-exercise recovery period. This decline, if not corrected, lead to acidosis and muscle soreness. Studies showed the positive effects of L- Glutamine supplementation on muscle strength recovery and muscle soreness reduction after intense exercises.*
