Melatonin is a naturally occurring hormone produced by the pineal gland, integral to regulating the body’s circadian rhythm and sleep-wake cycle. As a dietary supplement, synthetic melatonin is widely utilized to address sleep disorders, jet lag, and shift work sleep disturbances. Its role extends beyond sleep induction to potential antioxidant properties and modulation of immune function. Expert clinical guidance supports its use for specific populations under appropriate conditions.
Features
- Synthetic formulation identical to endogenous melatonin
- Available in immediate-release, extended-release, and sublingual forms
- Standardized dosing ranging from 0.3 mg to 10 mg per unit
- Typically vegan-friendly, gluten-free, and non-GMO in reputable brands
- Laboratory-tested for purity and potency assurance
Benefits
- Facilitates faster sleep onset by reducing sleep latency
- Helps realign circadian rhythms disrupted by travel or irregular schedules
- May improve overall sleep architecture, including increased REM sleep
- Supports adaptation to night shift work schedules
- Provides a non-habit forming alternative to prescription sleep aids
- Potentially offers neuroprotective and antioxidant benefits
Common use
Melatonin is primarily indicated for the short-term management of sleep disorders, particularly insomnia characterized by difficulty falling asleep. It is extensively used for mitigating jet lag symptoms following transmeridian travel, often recommended for travelers crossing two or more time zones. Shift workers frequently utilize melatonin to adapt to non-traditional work hours and improve daytime sleep quality. Off-label uses include managing sleep disturbances in children with neurodevelopmental disorders, though this requires pediatrician supervision. Some clinical evidence supports its adjunctive use in certain headache disorders and as an antioxidant therapy in specific contexts.
Dosage and direction
Initiate therapy with the lowest effective dose, typically 0.3–1 mg taken 30–60 minutes before desired sleep time. For jet lag, doses of 0.5–5 mg have been studied, with timing adjusted relative to destination timezone—generally taken at bedtime upon arrival. Shift workers should take melatonin approximately 30 minutes before their daytime sleep period. Extended-release formulations may be preferable for sleep maintenance insomnia. Sublingual forms offer faster absorption for sleep onset difficulties. Duration of use should generally not exceed 3 months without medical supervision. Always consult a healthcare provider for personalized dosing recommendations.
Precautions
Discontinue use and consult a healthcare provider if no improvement in sleep occurs after 2 weeks. Use caution when operating machinery or driving until individual response is established. May cause drowsiness that persists into the following day, particularly with higher doses. Not recommended for use during pregnancy or breastfeeding due to insufficient safety data. Individuals with autoimmune disorders, seizure disorders, or depression should exercise particular caution and seek medical advice before use. Regular monitoring is advised for long-term users.
Contraindications
Absolute contraindications include known hypersensitivity to melatonin or any product components. Should not be used by organ transplant recipients due to potential immunostimulatory effects. Contraindicated in patients taking immunosuppressive therapy. Not recommended for individuals with rheumatoid arthritis, lupus, or other autoimmune conditions without specialist consultation. Avoid use in those with severe hepatic impairment.
Possible side effects
Common side effects (≥1/100 to <1/10) include daytime drowsiness, headache, and dizziness. Less frequently (≥1/1,000 to <1/100), users may experience nausea, irritability, mild anxiety, or vivid dreams. Rare cases (≥1/10,000 to <1/1,000) include abdominal discomfort, reduced alertness, or transient depression. These effects are typically dose-dependent and often diminish with continued use or dose reduction.
Drug interaction
Melatonin may interact with anticoagulants/antiplatelets (warfarin, aspirin) potentially increasing bleeding risk. Concurrent use with sedatives (benzodiazepines, zolpidem) or CNS depressants (alcohol, antihistamines) may potentiate sedation. May reduce effectiveness of antihypertensive medications. Immunosuppressants (cyclosporine, corticosteroids) may have reduced efficacy. Anticonvulsants (valproate, carbamazepine) may alter melatonin metabolism. Fluvoxamine and other CYP1A2 inhibitors can significantly increase melatonin concentrations. Oral contraceptives may elevate endogenous melatonin levels, requiring dose adjustment.
Missed dose
If a dose is missed and the desired sleep time has passed, skip the missed dose entirely. Do not take melatonin during waking hours or double the next dose. Resume regular dosing schedule at the next intended sleep period. Consistent timing is crucial for maintaining circadian rhythm synchronization.
Overdose
Symptoms of significant overdose may include excessive sedation, confusion, disorientation, and hypothermia. Doses up to 30 mg have been studied without serious adverse effects, though individual sensitivity varies. Treatment is supportive: ensure airway protection, monitor vital signs, and provide symptomatic care. Gastric lavage or activated charcoal may be considered if ingestion occurred within 1 hour. There is no specific antidote. Contact poison control (1-800-222-1222) or seek emergency medical attention for guidance.
Storage
Store at controlled room temperature (20–25°C or 68–77°F) in original packaging. Protect from light and moisture. Keep tightly closed when not in use. Do not freeze. Keep out of reach of children and pets. Discard after expiration date printed on packaging. Do not transfer to alternative containers that may compromise stability.

This product is not intended to diagnose, treat, cure, or prevent any disease. These statements have not been evaluated by the Food and Drug Administration. Consult with a healthcare professional before starting any new supplement regimen, particularly if you have pre-existing medical conditions or take prescription medications. Individual results may vary. Proper diagnosis of sleep disorders should be made by a qualified physician.
Reviews
Clinical studies demonstrate melatonin reduces sleep onset latency by approximately 4–8 minutes compared to placebo. Systematic reviews indicate moderate efficacy for jet lag symptoms, particularly when crossing 5+ time zones. Patient reports frequently mention improved sleep quality and morning alertness, though some note residual drowsiness with higher doses. Long-term efficacy data remains limited beyond 3 months of continuous use. Overall satisfaction rates range from 60–75% in various consumer surveys when used for appropriate indications.
