A popular favourite with fitness enthusiasts, glutamine is the most abundant amino acid in skeletal muscle tissues, where it works to promote strength and endurance, but that's not all it does.

Glutamine's unique molecular structure allows it to pass through the blood / brain barrier to nourish vital brain tissues.

Once in the brain, glutamine is converted to glutamic acid, the base material for key neurotransmitters necessary for the healthy functioning of the nervous and mental systems.
