Source Naturals L-Glutamine, Free Form Amino Acid That Supports Metabolic Energy* - 16 oz Powder

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 suggested use is 1/4 to 1/2 teaspoon daily between meals. Please contact our in-house customer support if you have any questions.

• 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.
