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.

Each bottle contains 120 vegan capsules and provides 120 servings. The only other ingredient is hypromellose, a plant-based cellulose capsule. Powder settling may occur because each capsule is filled by weight without added fillers.

The formula is non-GMO, vegan, vegetarian, kosher, dairy-free, egg-free, soy-free, nut-free, and made without gluten. NOW Foods packages and quality-tests this product in the United States under third-party-certified GMP standards. Natural color variation may occur. This adult-only supplement is intended for health-conscious buyers seeking transparent, routine-friendly free-form L-phenylalanine.
