How much melatonin gummy labels list
Most gummy labels list a bigger serving than our 2.5 mg gummy pick. We read 100 melatonin gummy labels in the NIH Dietary Supplement Label Database (September 18, 2026). The median gummy held 2.5 mg. The median serving was 5 mg, taken as 2 gummies, and 64% of labels listed 5 mg or more a serving.
Most studies used 0.5 to 5 mg. How much to take · is 1 mg enough?
Do gummies hold what the label says?
Often not. A 2023 JAMA study measured the melatonin in 25 gummy brands sold in the US. 22 of 25 were off by more than 10%. Those with melatonin held 74% to 347% of the label amount. One had no melatonin at all but held 31.3 mg of CBD (Cohen 2023).
The study tested one sample per brand and only gummies, so it cannot say whether tablets do better or whether batches vary.
Our gummy pick is on USP Verified; USP says it checks that a product holds the ingredients on the label. Which melatonin is on a testing list, and what other lab tests found.

Children and gummies
Gummies look like candy, so keep them out of reach. Poison center calls about children and teens swallowing melatonin rose 530% from 2012 to 2021 (Lelak 2022, CDC). The report summary we read does not say how many involved gummies. Ask a doctor before giving melatonin to a child. If a child swallows melatonin, call Poison Help at 1-800-222-1222.

Questions
How many mg of melatonin is in a gummy?
It depends on the brand. The gummies we score hold 1 to 5 mg each. On 100 gummy labels we read in the NIH label database, the median gummy held 2.5 mg, and the median serving was 5 mg from 2 gummies. Check the serving size: one gummy may be half a serving.
Is a 5 mg melatonin gummy too much?
5 mg is at the top of the range most studies used. For jet lag, more than 5 mg worked no better (Herxheimer 2002). Our side effects page covers higher doses.
Do melatonin gummies contain what the label says?
Often not. A JAMA study tested 25 gummies: 22 were off by more than 10%, from 74% to 347% of the label, and one had no melatonin (Cohen 2023). It tested one sample per brand.
Are melatonin gummies as good as pills?
We found no study that compares them for sleep. The JAMA label study tested only gummies, so it cannot say whether tablets are more accurate. Per night, gummies cost more than most tablets we score.
When should I take a melatonin gummy?
The gummy labels we read say 30 minutes to 1 hour before bed. Trials gave melatonin anywhere from 30 minutes to about 4 hours before bed. See our dosage guide for what each study did.
Are melatonin gummies safe for kids?
Ask your child’s doctor first. NIH says the best dose, timing and long-term effects in children are not known. Gummies look like candy, and poison center calls about children swallowing melatonin rose 530% from 2012 to 2021 (Lelak 2022). Keep them out of reach.
