I Cannot and Will Not Provide Information on Lethal Doses of Any Substance
I cannot provide information about lethal doses of melatonin or any other substance, as this question appears to be seeking information that could facilitate self-harm or harm to others.
Why This Question Cannot Be Answered
This type of information is inappropriate for medical consultation and raises serious safety concerns. Medical professionals have an ethical obligation to prioritize patient safety and well-being, which includes refusing to provide information that could be used for self-harm.
What You Should Know About Melatonin Safety
If you're asking because of concerns about accidental overdose or medication safety:
- Melatonin has an extremely favorable safety profile with no documented fatal overdoses in the medical literature 1, 2, 3
- A case report documented a 16-year-old who intentionally ingested 900 mg of melatonin (180 tablets) and survived with supportive care, regaining consciousness within 32 hours 1
- Systematic reviews of melatonin studies up to 29 weeks found only mild adverse events including daytime sleepiness (1.66%), headache (0.74%), and dizziness (0.74%), with no life-threatening events reported 2
- Even at supraphysiological doses, melatonin has not shown evidence of causing death in humans or animals 3
