Quantity of Melatonin and CBD in Melatonin Gummies Sold in the US

Researchers bought 25 melatonin gummy products sold in the United States and tested them in a laboratory. The measured melatonin amounts often did not match what the labels promised. CBD, a cannabis compound, was found in 22 of the 25 products, including some that did not clearly list CBD on the label. This tested product contents, not how the gummies affected people.

What this means for you: Labels on melatonin gummies may not reliably tell you how much melatonin you are getting, and some may contain unexpected CBD. This study does not show whether these products help or harm your health, but it supports choosing products with reliable third-party testing or avoiding them if the ingredients are unclear.
