Melatonin and sleep: useful questions before the supplement aisle.
Separate a possible sleep benefit from claims about treating autism or ADHD itself.

THE USEFUL DISTINCTION
NCCIH describes short-term sleep benefits in some children, including children with autism or ADHD. Long-term safety and the right approach for an individual remain questions for a healthcare professional.[1]
What the evidence addresses
NCCIH summarizes research suggesting melatonin can help some children fall asleep sooner and sleep longer. Many studies were small and short. The agency notes uncertainty about long-term use, timing, and dose.
NCCIH also warns that product contents may differ from labels and that interactions are possible. It recommends speaking with a healthcare provider before giving melatonin to a child.[1]
Make the conversation specific
Bring a description of the sleep problem and a list of medicines and supplements to the appointment. Ask what is being treated, how improvement would be assessed, and what follow-up is appropriate.
This page deliberately does not recommend a brand, a dose, or a trial schedule.
Who does this apply to?
Research summarized by NCCIH includes children with sleep difficulties, including some with autism or ADHD.
What remains uncertain?
A result about falling asleep is not evidence of treating core autism or ADHD characteristics. Studies in children do not automatically apply to adults.
Questions for your clinician
These are conversation prompts, not a suggested treatment plan.
- What might be contributing to the sleep difficulty?
- What non-supplement approaches should we consider?
- Could it interact with current medicines or health conditions?
- How would we assess benefit, side effects, and ongoing need?
