L-Phenylalanine is an essential amino acid that converts to tyrosine. It follows the catecholamine pathway and is a precursor to thyroid hormone. L-Phenylalanine helps support the normal production of mood-elevating chemicals in the brain such as dopamine and norepinephrine. The L form may help support normal mood and attention. It should not be used with MAO inhibitors or tricyclic antidepressants, or by patients who have PKU, or hypertension. *

Description: L-Phenylalanine is an essential amino acid that is converted to tyrosine. It follows the catecholamine pathway and is a precursor to thyroid hormone. L-Phenylalanine helps support the normal production of mood-elevating chemicals in the brain such as dopamine and norepinephrine.  The L form of phenylalanine may help support normal mood and attention. It should not be used with MAO inhibitors or tricyclic antidepressants, or by patients who have PKU, or hypertension.

Uses: Insufficient activity of the neurotransmitters serotonin and norepinephrine is a central element of the model of depression most widely held by neurobiologists today. The synthesis of most neurotransmitters is controlled within the brain, and for some neurotransmitters, the amount of biochemical precursors present in the brain can influence their rate of synthesis [1]. Reduced serotonin and/or catecholamine neurotransmission increases vulnerability to lowered mood. As L-phenylalanine is a precursor for neurotransmitter production, its supplementation can support the maintenance of a balanced mood [2].

There is a substantial body of literature linking the B vitamins with mood. Vitamin B-6 intake has also been positively associated with memory performance. Research indicates vitamin B-6 may act as a catalyzing cofactor in methylation in the central nervous system, thereby influencing cognitive function and mood [3].
