L-Glutamine plays an important role in many bodily functions – one of them is brain function. It converts more quickly into glucose than other amino acids helping maintain healthy blood sugar levels. As it can pass the blood-brain barrier, it is known as brain fuel. Increasing cerebral function, it is possible that it will reduce depression.
