NOW Foods L-Phenylalanine 500 mg Free-Form Amino Acid – 120 Veg Capsules

NOW Foods L-Phenylalanine 500 mg is a free-form essential amino acid supplement designed to support protein synthesis and healthy nervous system function. Each vegetable capsule supplies 500 mg of L-phenylalanine in a simple formula without added fillers, making it a quality-focused choice for adults seeking straightforward amino acid support. L-phenylalanine is an essential amino acid, meaning the body must obtain it through food or supplementation. In addition to contributing to normal protein synthesis, L-phenylalanine can be converted into tyrosine. Tyrosine forms part of the structure of the neurotransmitters dopamine and norepinephrine, supporting the formula's role in nervous system wellness.
