L-Phenylalanine 500 g

Why Phenylalanine Remains a Core Ingredient for Sports Nutrition and Skin Formulas

L-Phenylalanine is an essential amino acid the body cannot produce on its own, which is why global demand for this raw material is concentrated primarily in functional food, sports nutrition, and pharmaceutical manufacturing. This amino acid acts as a precursor to key neurotransmitters, making it a popular choice in formulas designed to support mental focus and overall energy levels. This item is listed under Amino Acids, a section featuring raw materials for protein blends, capsule supplements, powdered drinks, and cosmetic formulations.

In the food and sports industry, L-Phenylalanine is incorporated into protein shakes, pre-workout blends, and recovery mixes at dosages ranging from 200 to 1000 mg per serving, depending on the overall formula and target purpose. The ingredient dissolves readily in water and can be added during the dry-mixing stage without heating, which simplifies production while preserving the amino acid's activity. In pharmaceutical manufacturing, phenylalanine is used in nutraceuticals, vitamin-mineral complexes, and specialized blends aimed at people under increased physical or mental strain.

A separate application area is skin care, where phenylalanine is introduced into serums, creams, and toning emulsions as an ingredient supporting the skin's barrier function and playing a role in melanin pigment synthesis. In formulations, its concentration typically ranges from 0.5 to 2 grams per 100 grams of the finished product, and it should be added to the water phase at a temperature not exceeding 40 degrees Celsius to prevent breakdown of the molecule. Phenylalanine pairs well with other amino acids, allowing manufacturers to build multi-functional blends: combined with Taurine 10 g, it appears in energizing and toning products, while paired with L-Cysteine, 10 g, it is often found in complexes aimed at hair and nail support. Phenylalanine can also be combined with Asparagine 10 g when developing multi-component amino acid blends for sports and functional nutrition products.

The 500 g package size is convenient for small manufacturers, labs, and studios that develop their own recipes in small to medium batches, test dosages, and prepare trial production runs before scaling up. Store the raw material in a dry area protected from direct light, in a tightly sealed container, avoiding moisture exposure, which helps maintain the amino acid's stability throughout its shelf life.
