Tryptophan is an essential amino acid that acts as a precursor of serotonin, a neurotransmitter in the nervous system. Serotonin is a modulator that acts by improving our mood, perception, memory, attention and reduces states of stress and aggression. High stress levels, as well as states lacking tryptophan, reduce the concentration of serotonin in our body, causing fatigue, feelings of discouragement, apathy and ultimately depression. Tryptophan is the perfect complement to help those people who feel unmotivated, stressed or who need extra help to improve their memory and/or attention.
