About L-Tryptophan

Why are people looking for Tryptophan? 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.

You can ask the supplier about all relevant certificates for the product such as CoA, Safety Data Sheet and DMF.
