Phenylalanine supplementation helps in the production of neurotransmitters (dopamine, norepinephrine, and epinephrine). Clinical trials suggest that it can promote positive mood. Phenylalanine is an essential amino acid, which means that your body cannot produce sufficient amounts and requires it from an external source. It is converted to L-tyrosine in the liver, which is then converted to the hormones dopamine, norepinephrine, and epinephrine (adrenaline) that can be depleted for a variety of reasons. Replenishing norepinephrine in the brain can support brain health.
