PROCESS AND COMPOSITION FOR INCREASING DOPAMINE AND NOREPINEPHRINE LEVELS IN NEURAL SYNAPSES

摘要

The levels of dopamine and/or norepinephrine in neuronal synapses are regulated by administering a neutral amino acid composition to a human wherein increased or decreased brain levels of dopamine and/or norepinephrine are effected when the compostion contains increased or decreased amounts of tyrosine and/or phenylalanine. Increased or decreased brain levels of serotonin are obtained when the amino acid composition contains increased or decreased amounts of tryptophan. The neutral amino acid composition can be administered alone or concomitantly with a drug which increases or decreases dopaminergic or noradrenergic neurotransmission.
