Why it is included
L-Tryptophan is included as part of Calm's mood building block active ingredients.
L-Tryptophan is an essential amino acid and a nutritional precursor to serotonin, a neurotransmitter involved in mood, emotional regulation, and behavioural balance. In dogs, tryptophan has been studied in relation to anxiety-related behaviour and stress responses. Its role in the formula is to provide nutritional support for the serotonin pathway, helping support a steadier and more balanced mood.
