Pure Encapsulations DL-Phenylalanine is a dietary supplement providing DL-phenylalanine in free-form, delivered in a vegetarian capsule. DL-phenylalanine is a combination of d-phenylalanine and l-phenylalanine, formulated to support mental acuity, emotional well-being, and musculoskeletal relaxation.
L-phenylalanine is a precursor to tyrosine, which in turn serves as a precursor to the neurotransmitters norepinephrine, epinephrine, dopamine, and tyramine. Tyrosine and its metabolites are associated with support for emotional well-being, memory, and learning. D-phenylalanine is noted by the manufacturer as supporting levels of certain endorphins, contributing to musculoskeletal relaxation.
