Drug Info: DrugBank

DrugBank ID	DB00150
Name	Tryptophan
Groups	nutraceutical approved withdrawn
Description	An essential amino acid that is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of indole alkaloids in plants. It is a precursor of serotonin (hence its use as an antidepressant and sleep aid). It can be a precursor to niacin, albeit inefficiently, in mammals.
