Are Melatonin Gummies Accurately Labeled?

By Dr. Ryan Kneessi, ND, Move Forward Natural Health. Last reviewed October 23, 2026.

Melatonin gummies are one of the most popular sleep products in the country, and many households keep them in the kitchen cabinet. It is worth knowing what is actually in the bottle.

What did the 2023 study find?

Researchers led by Dr. Pieter Cohen bought 25 melatonin gummy products and measured what was inside. They reported that most did not contain the amount listed on the label. Several had much more melatonin than stated, and at least one had none that could be detected. Some products labeled as containing CBD also had amounts that differed from the label.

Why does this matter?

In the US, melatonin is sold as a dietary supplement, so products are not tested before they reach the shelf. Gummies can also look and taste like candy, which matters in homes with children. Keeping them out of reach is an important safety step.

What should I look for in a sleep supplement?

Look for brands that publish third-party testing, choose the lowest amount that fits your needs, and check with your provider if you take other medications. Many people also find that their sleep routine, light exposure, and evening habits matter as much as any supplement.
