L-Tryptophan Powder - Certified Food Grade

L-Tryptophan is an essential amino acid — one the body cannot manufacture on its own and must obtain through the diet. It serves as the metabolic precursor to serotonin (a neurotransmitter associated with mood and sleep) and to niacin (vitamin B3), and plays a foundational role in protein synthesis.

Our certified food-grade L-Tryptophan is a fine, off-white crystalline powder with a high assay purity, manufactured to food-grade specification and suitable for use in nutritional and functional formulations. It is soluble in water and blends readily into powders, capsules, beverages, and other supplement formats.

Typical applications: dietary supplement blends, sleep and mood formulations, functional foods and beverages, sports nutrition recovery products.

Suggested use: commonly formulated at 500 mg–1 g per serving, or as directed by your formulation requirements.

Appearance: off-white crystalline powder. Solubility: soluble in water. Storage: keep sealed in a cool, dry place away from direct sunlight and moisture.
