Phenylalanine supplementation helps in the production of healthy neurotransmitters (dopamine, norepinephrine and epinephrine). Clinical trials suggest it may promote positive moods.

What Is D, L-Phenylalanine Capsules?

Phenylalanine is an essential amino acid, which means your body can’t produce sufficient amounts and requires it from an external source. It’s converted to L-tyrosine in the liver, which is then converted into dopamine, norepinephrine and epinephrine (adrenaline) hormones that can become depleted for a variety of reasons. Replenishing norepinephrine in the brain can support brain health.

The neurotransmitters produced from phenylalanine supplementation bring a wide range of cognitive health benefits.

Essential Nutrient to Support Mood and Cognitive Health

D,L-phenylalanine is a 50/50 mixture of its two stereoisomers that can be converted to L-tyrosine in the liver, which is then used to make dopamine, norepinephrine and epinephrine. In addition to acting as a neurotransmitter that supports healthy mood and sleep, norepinephrine is known to protect brain cells by promoting a healthy inflammatory response, inhibiting oxidative stress and supporting healthy neuronal growth.

Phenylalanine is an essential amino acid that can be converted to L-tyrosine in the liver. Tyrosine is used in the nervous system to make a class of neurotransmitters called catecholamines: dopamine, norepinephrine and epinephrine. Epinephrine, made from tyrosine in the adrenal medulla, functions as a neurohormone and is known as adrenaline.
