L-Glutamine, a free-form amino acid, can be converted to glutamic acid. Glutamic acid is a usable energy source for the brain and a precursor to the important inhibitory neurotransmitter GABA (gamma-aminobutyric acid). L Glutamine also plays an important role in ammonia disposal.

  • The brain needs glumatic acid as a fuel to power numerous brain functions but it cannot cross the blood brain barrier. l-Glutamine can more easily enter the brain and be converted into glutamic acid, a neurotransmitter believed to support mental alertness and mood.*
