Glutamic acid, a free form
amino acid, and glucose are the only two sources of energy the brain can use. Glutamic acid does not cross the "brain-blood-barrier" easily, so it is not very bioavailable, but l-glutamine, also a free-form amino acid, can cross the barrier easily. It is then converted to glutamine acid for energy production. L-glutamine is also a precursor for gaba (gamma amino butyric acid), an important relaxing or inhibitory neurotransmitter.
Ingredients:
