Glutamine

L-Glutamine is the most common amino acid found in the human body. It plays a vital role in protein metabolism, shunting nitrogen into the muscle tissue. Glutamine helps to build muscle by increasing the levels of leucine within the muscle fibres and it also decreases muscle fatigue enabling you to work longer and harder at the gym. This key amino acid boosts your immune function which enables you to recover quicker post exercise and it increase your human growth hormone levels which are essential for building muscle mass.
