Chibio’s L-Tryptophan Crystals are USP32-grade, fermentation-derived amino acids vital for serotonin and melatonin synthesis. Ideal for use in pharmaceutical, nutraceutical, and mental wellness formulations.
L-Tryptophan is an essential amino acid required for the biosynthesis of serotonin (a mood stabilizer), melatonin (a sleep regulator), and niacin (vitamin B3). Because it cannot be synthesized by the body, it must be obtained from dietary or supplemental sources.
Chibio’s L-Tryptophan is produced via precision microbial fermentation to ensure high purity (99.23%) and strict USP32 compliance. It is ideal for use in sleep aids, stress relief formulas, neuroprotective blends, and functional wellness products.
Key highlights:
Fermentation-based, non-animal origin
High-purity crystalline powder
Safe for vegan, halal, kosher, and clean-label formulations
Suitable for clinical-grade dietary supplements and functional food products
