What is Melatonin and what is it used for?
Melatonin is an endogenous chronobiotic hormone that helps regulate sleep-wake timing and circadian phase. Supplemental melatonin has good evidence for sleep-onset support and circadian misalignment contexts, while effects on total sleep duration are typically smaller and population dependent.
Melatonin is commonly used for sleep-onset support and circadian rhythm adjustment. The strength of support can vary by use case, dose, and product quality.
How to choose
Timing relative to desired sleep phase is usually more important than using higher doses.

What to avoid when choosing a melatonin supplement
Proprietary blends
Avoid formulas that hide key ingredient amounts behind proprietary blends or vague serving details.
Unclear dose labeling
Products that make the melatonin amount hard to compare with clearly labeled options like the top-ranked product's 3 mg per serving.
Vague claims without dose
Treat broad claims cautiously when the label does not make the dose, form, or active ingredient easy to verify. Treat third-party tested claims as useful only when the brand clearly identifies the test, certification, or batch documentation.
Unnecessary complex formulas
Multi-ingredient formulas can be harder to compare, especially when the main melatonin ingredient is not clearly separated from supporting ingredients.
