Our Members Asked:
Do pistachio nuts really provide as much melatonin as supplements?
Reviewed and edited by Tod Cooperman, M.D.
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.Join today to unlock all member benefits including full access to all CL Answers and over 1,300 reviews.

February 28, 2019A friend gets terrible arthritis in the knees if he eats Pistachio nuts. And, the pain comes quickly. I wonder if such also affects other people.

February 25, 2019There is limited research, however continued use of melatonin has been associated with osteoporosis. I had been weight lifting for many years and a simple fall caused a bimaleolar ankle fracture. Weight-bearing exercise increases bone density and this was not true for me, as I tested positive for osteopenea.
