Glutamine is highly concentrated in
the brain , being 10-15 times more concentrated in
the cerebro-spinal fluid than in
the blood. It is an important fuel for the brain, & can provide adequate energy in the absence of glucose (the other major brain fuel). For this reason it is helpful with focus, concentration, memory, intellectual performance, alertness, attentiveness, improving mood, & eliminating brain fog & cloudiness.
I hope all goes well for you. it should!
