Label doses and test results
Melatonin gummies are commonly sold at 1 to 10 mg each. Four gummies could equal 4 to 40 mg, depending on the product. Doses used in studies for sleep are often 0.5 to 5 mg, and many experts say 1 to 3 mg is enough. A 2023 JAMA research letter tested 25 gummy products and found actual melatonin content ranged from 74 to 347 percent of the label.
- Some products also contained CBD.
- The American Academy of Sleep Medicine recommends against routine melatonin for children without medical guidance, and calls for caution in adults.
- Reports of pediatric melatonin ingestions to US poison centers rose by more than 500 percent from 2012 to 2021, per CDC data.
Side effects and advice
High doses may cause morning grogginess, headache, nausea, dizziness, vivid dreams and low body temperature. It can interact with blood thinners, diabetes drugs and sedatives. A single high dose is unlikely to be dangerous in a healthy adult, but call Poison Control (1-800-222-1222) for large ingestions, especially in children. Choose third-party tested products, such as those with USP verification, and take only at bedtime.
Label doses and test results
Melatonin gummies typically contain 1 to 10 mg. A 2023 JAMA study found that products had between 74 and 347 percent of the labeled amount. Four gummies may equal 12 to 40 mg or more.
Side effects and advice
Side effects include drowsiness, headache and vivid dreams. Overdose is rarely dangerous in adults but call poison control (1-800-222-1222) if a child ate them. Poison control received many calls about child ingestions.
Dose and effects
Melatonin gummies commonly contain 1 to 10 milligrams each. Four gummies could total 4 to 40 milligrams. Typical adult doses used in studies are 0.5 to 5 milligrams, and higher doses do not work better. Excess can cause headache, nausea, dizziness, daytime drowsiness, vivid dreams and irritability. A 2023 JAMA study found that melatonin gummies often contained quantities different from the label, from about 74 to 347 percent of the labeled amount.
What to do
Most healthy adults will sleep and may feel groggy, and serious toxicity is rare. Avoid driving. Do not take more. Children are at risk, and the CDC reports increased pediatric ingestions, so keep bottles locked away. Call poison control at 1-800-222-1222 for a child or an unusually high dose, and seek care for severe symptoms. Check with a doctor if on blood thinners, seizure medicines or sedatives.
