The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an essential amino acid that helps with protein building and acts as a precursor to serotonin, a brain chemical tied to mood, sleep and cognitive function.

This form is the naturally occurring amino acid used in dietary supplements to supply tryptophan for body processes, and research has noted its part in serotonin synthesis and related functions.

What Does L-Tryptophan Do?

L-Tryptophan participates in brain serotonin synthesis, a process tied to mood regulation and sleep-related mechanisms. Research discussion also notes its potential role in supporting sleep quality through serotonin and melatonin pathways.

Dr. Richard at the University of Rochester Medical Center found that tryptophan's role in brain serotonin synthesis is an important factor in mood, behaviour and cognition.
