Tryptophan is an essential amino acid, which means that the body cannot produce it itself. To meet the daily requirement, tryptophan must be ingested through food. A supplement can be an addition to this.
Natural L-form of Tryptophan
Our tryptophan supplement contains the natural L-form. This form is carefully produced through an advanced fermentation process, which uses microorganisms to synthesize the natural L-tryptophan form. This process ensures a high quality and purity of the supplement.
