Tryptophan, also known as L-Tryptophan, is an essential amino acid. This means that it is vital for the body, but the body cannot produce it on its own. Therefore, we must obtain it from external sources.
Functions of Tryptophan in the Body
Tryptophan is important for the production of the neurotransmitter serotonin. Serotonin is also known as the “happiness hormone.” Mood swings and feelings of low mood can be linked to a serotonin deficiency.
A sufficient serotonin level is also crucial for healthy melatonin production, which in turn supports good sleep. As a precursor to serotonin, tryptophan can promote deep and restful sleep. Serotonin and tryptophan also play a role in memory performance.
