Tryptophan is a precursor to serotonin, a neurotransmitter that is often associated with feelings of calmness and well-being. Increasing tryptophan levels in an animal's diet can help to reduce aggressive behavior by increasing serotonin levels. Phenylalanine, on the other hand, is a precursor to dopamine and norepinephrine, which can actually increase aggression in some cases. Decreasing thiamine or lecithin may have no effect on aggressive behavior in animals.
