Gluten Free Non-GMO LE Certified Enhances Mood Dietary Supplement What Are 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 Helps promote healthy mood & sleep Supports healthy cognitive function Provides protection for brain cells
