L-Tryptophan is an essential amino acid and a direct precursor to the neurotransmitter serotonin.
L-Tryptophan is characterized by its role in regulating behavior, sleep, and stress responses in animals. It acts as a natural calming agent in pet food and specialty feeds, helping to manage aggression and promote overall neurological well-being.
