Glutamine is the most abundant non-essential free amino acid in your body – more than 20% of the total circulating amino acids in your body are glutamine. Your muscles are especially high in glutamine, making it extremely important for muscle metabolism. When you’re training hard, your muscles can lose up to 50% of their glutamine stores, so you need to replace them fast! WHO SHOULD USE IT Glutamine, is designed for everyone, from active men and women and fitness enthusiasts to high-performance athletes, powerlifters, crossfitters, bodybuilders, endurance athletes, and anyone looking to boost their glutamine intake to help replenish plasma glutamine, and support cell volumization, protein synthesis and glycogen replenishment after training. STACK IT Glutamine can stack with any supplement you’re using. Try stacking it with a creatine supplement like Creactor along with Clear Muscle for a great musclebuilding stack! Direction use: take one serving before and after exercise and one serving befor bed.
