What is Tryptophan?



Because tryptophan is one of the nine essential amino acids, it is considered a key element to helping stimulate muscle protein synthesis. Furthermore, tryptophan has been studied a great deal both in exercise and some clinical populations for its role in governing fatigue, mood, etc, due to the increased production of serotonin, a key neurotransmitter in the brain associated with mood and other biological activity.
