Tryptophan is one of the more well known essential amino acids due to its association with sleepiness and the key neurotransmitter serotonin. Via serotonin, tryptophan is able to have a considerable influence on overall mental health, and in particular sleep and mood regulation.

Furthermore, it is considered a natural painkiller that has influence in preventing symptoms of premature aging.
