Question: Do pistachio nuts really provide as much melatonin as supplements?
Answer: A small study in Iran reported extraordinary concentrations of melatonin in locally obtained pistachios -- more than 100 to 1,000 times the concentrations reported in other plants and foods by other researchers. However, the results of this study are questionable, as discussed in the Melatonin Supplements Review. Until another laboratory confirms these findings, don't count on getting significant amounts of melatonin from pistachios.
