L-Phenylalanine 5 g

The building block behind sports nutrition, mood-support formulas, and brightening skincare

L-Phenylalanine is an essential aromatic amino acid that the body cannot produce on its own, which is why the strongest global demand for this raw material comes from the food and sports nutrition industry. It is blended into protein powders, capsule-based supplements, and functional drink mixes designed to support alertness and stamina. The pharmaceutical sector relies on it as a direct precursor to tyrosine, and further down the pathway to dopamine and norepinephrine, so it regularly appears in nootropic and stress-support formulations. This raw material is listed in the Amino Acids section, where formulators can find companion ingredients for both small home batches and pilot production runs.

In skincare manufacturing, phenylalanine draws attention for its role in melanin synthesis, which is why it shows up in serums and treatments aimed at supporting even skin tone and in recovery products used after intensive procedures. It also supports general cellular metabolism in the skin and pairs well with other active amino acids in a formula. A classic combination is phenylalanine paired with L-Tyrosine, since tyrosine is the next link in the biochemical chain and reinforces the overall effect of the blend. For formulas targeting emotional balance, phenylalanine is frequently combined with Griffonia Simplicifolia Seed Extract, which works through the parallel serotonin pathway. In sports recovery blends, it is often paired with L-Ornithine HCl to support post-workout recovery.

The 5 gram pack size is aimed at home formulators and small test batches, letting you fine-tune concentration and ingredient ratios before scaling up. Typical working dosages in supplement recipes range from 300 to 1000 mg per serving, adjusted according to the purpose of the formula and its companion ingredients. The powder should be added at the final stage of dry mixing, at room temperature, avoiding heat above 40 degrees Celsius since prolonged thermal exposure reduces amino acid activity. Store the raw material in a tightly sealed container, in a cool dry place away from direct sunlight, to preserve its potency throughout the shelf life.

Because small pack sizes require precise weighing, using a calibrated scale and clean equipment is essential to keep formula ratios consistent between batches. Good compatibility with plant extracts, B vitamins, and mineral blends makes this amino acid a convenient building block for expanding a functional product lineup.
