AAN Ultra-Calm is a calmer, not a sedative.
L-Tryptophan is the active ingredient in this potent formulation. L-Tryptophan is an amino acid that naturally occurs in animal and plant proteins. Once absorbed, Tryptophan is converted into Serotonin which is known as the ‘happy hormone’. Serotonin reduces anxiety and stress naturally without dulling the senses. Ultra-Calm is effective within 90 minutes and has about 3 to 4hr half-life (this may vary from horse to horse)
