Tryptophane has a role as an antidepressant, a nutraceutical, a micronutrient, a plant metabolite, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tryptophan and a L-alpha-amino acid.
There are a number of health benefits from the naturally occurring tryptophan found in foods. Most of these health benefits come from the potential increase of niacin and thus serotonin. The benefits from more serotonin include: healthier and better quality sleep；relief from depression and anxiety；increased emotional well-being and
strengthened pain tolerance.
