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.

A 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.

There 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.

Hi Anne Marie - Thank you for sharing this. You can find more information about melatonin's effect on bone density and the risk of fractures in the "Cautions and Concerns" section of the Melatonin Review: https://www.consumerlab.com/reviews/melatonin-supplements/melatonin/#bone.
