Glutamine, one of the most abundant amino acids found in skeletal muscles, serves as fuel for the immune system, provides an anti-catabolic effect and is involved in protein synthesis.*  Prolonged high-intensity exercise has shown to decrease glutamine levels, which may result in glutamine deficiency.  Supplementing with Pro Performance® Glutamine Powder may help in maintaining glutamine stores.  Each serving supplies 5 grams of L-Glutamine and blends easily with any beverage or sports drink.
