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.

D, L-Phenylalanine Benefits

  • Supports production of L-tyrosine, which is used to make dopamine, norepinephrine & epinephrine
