Glutamic acid can be used as fuel in the brain. It can attach itself to nitrogen atoms in the process of forming glutamine, which detoxifies the body of ammonia. This action is the only way in which the brain can be detoxified from ammonia.

Glutamic Acid is an excitatory neurotransmitter for the central nervous system, the brain and spinal cord; important in the metabolism of sugars and fats.  It aids in the transportation of potassium into the spinal fluid.  Glutamic Acid acts as fuel for the brain. 

fUS utilizes single, free form, pharmaceutical grade glutamic acid. This is not the bulk free glutamic acid used in processed foods and may be identified with MSG which has many dangerous side effects.
