Vitals L-Tryptophan 400 mg (60 capsules) contains the essential amino acid L-tryptophan. This amino acid is naturally found in protein-rich foods such as dairy, meat, eggs, and nuts. Since the body cannot produce L-tryptophan on its own, it must be obtained from food, optionally supplemented with a supplement.
