Created for athletes to refuel after demanding activity, GU Recovery Drink Mix packs energy-dense whey protein isolate to promote protein synthesis and reduce muscle-protein breakdown. The carbohydrate, dextrose, helps replenish glycogen stores and also play a role in inhibiting exercise-stimulated muscle-protein breakdown. The amino acid arginine (1400mg) is the rate-limiting amino acid in nitric oxide production, which can potentially increase vasodilation and improve oxygen transport. The amino acid glutamine (2800mg) helps promote proper immune function. Sodium, the primary electrolyte lost in sweat, aids in rehydration by maintaining water balance.
