Life Extension D, L-Phenylalanine

Overview

Life Extension D, L-Phenylalanine is a dietary supplement made with the essential amino acid D, L-phenylalanine. The formula is presented in capsule form and is designed to help support mood, cognitive function, and overall brain health.

Phenylalanine must be obtained from outside sources because the body cannot produce enough of it on its own. In the body, it is converted to L-tyrosine in the liver, which then serves as a precursor for dopamine, norepinephrine, and epinephrine. Because these neurotransmitter related compounds can become depleted for different reasons, replenishing phenylalanine may help maintain healthy levels involved in normal brain function.

This product is also described as gluten free and Non GMO LE Certified. The suggested use notes that it is best taken together with vitamin B6 and vitamin C, which are identified as co-factors in the directions.
