Melatonin in pistachio nuts -- bowl of pistachio nuts

Answer:

Many nuts, including pistachios, as well as almonds, cashews, Brazil nuts, chestnuts and peanuts, contain very small concentrations of melatonin. Although pistachios contain higher concentrations of melatonin than some other nuts, no nuts have been found contain the amount of melatonin provided by supplements. For more details, see the ConsumerTips section of our Melatonin Supplements Review.

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.
