Melatonin is a naturally occurring hormone produced by the pineal gland, primarily responsible for regulating the sleep-wake cycle. As a dietary supplement, synthetic or animal-derived melatonin is widely utilized to address sleep disorders, manage circadian rhythm disruptions, and support overall sleep quality. Its role extends beyond sleep initiation to influencing various physiological processes, including antioxidant activity and immune modulation. Expert clinical guidance recommends its use under specific conditions to align with evidence-based outcomes.
Features
- Synthetic or natural-sourced melatonin identical to endogenous hormone
- Available in immediate-release, extended-release, and sublingual formulations
- Standardized dosages ranging from 0.3 mg to 10 mg per unit
- Typically vegan-friendly, gluten-free, and non-GMO in premium supplements
- Third-party tested for purity and potency in reputable brands
Benefits
- Promotes faster sleep onset by reducing sleep latency
- Helps realign circadian rhythms disrupted by jet lag or shift work
- Supports overall sleep architecture, including REM and deep sleep phases
- Exhibits antioxidant properties that may reduce oxidative stress
- Assists in managing sleep disorders like delayed sleep phase syndrome
- Non-habit forming compared to many prescription sleep aids
Common use
Melatonin is primarily indicated for the short-term management of insomnia, particularly sleep onset insomnia. It is frequently used by travelers to mitigate jet lag and by shift workers to adapt to irregular schedules. Off-label, it is sometimes utilized in supportive care for certain neurological conditions, such as migraine prophylaxis or to reduce anxiety before medical procedures. Pediatric use is generally restricted to specific sleep disorders under medical supervision.
Dosage and direction
Initiate with the lowest effective dose, typically 0.5–1 mg taken 30–60 minutes before desired sleep time. For jet lag, doses of 0.5–5 mg have been used, starting before departure and continuing for several days after arrival. Extended-release formulations may be preferable for sleep maintenance. Sublingual tablets offer faster absorption. Dosage should be individualized; higher doses (3–10 mg) are sometimes used under medical guidance but are not always more effective. Long-term use beyond 2–3 months should be supervised by a healthcare provider.
Precautions
Avoid activities requiring alertness, such as driving, after ingestion. Use caution in individuals with depression, as melatonin may exacerbate symptoms in some cases. Not recommended for use during pregnancy or lactation due to insufficient safety data. Those with autoimmune disorders, seizure disorders, or bleeding diatheses should consult a physician before use. Discontinue use at least two weeks prior to elective surgery due to potential effects on coagulation and anesthesia.
Contraindications
Melatonin is contraindicated in individuals with known hypersensitivity to melatonin or any component of the formulation. It should not be used by patients taking immunosuppressive therapy following organ transplantation. Avoid in those with severe hepatic impairment. Contraindicated in patients with rheumatoid arthritis, multiple sclerosis, or lupus unless explicitly approved by a treating specialist.
Possible side effects
Common side effects include daytime drowsiness, headache, dizziness, and nausea. Less frequently reported are vivid dreams, irritability, mild anxiety, or transient hypotension. Hypothermia and reduced sperm motility have been noted in high-dose studies. Most side effects are dose-dependent and resolve upon discontinuation or dose reduction.
Drug interaction
Melatonin may interact with anticoagulants (e.g., warfarin), increasing bleeding risk. It can potentiate effects of sedatives, including benzodiazepines, barbiturates, and alcohol. Concurrent use with immunosuppressants may reduce efficacy of both agents. May alter metabolism of drugs processed by CYP1A2 substrates (e.g., fluvoxamine, caffeine). Use with antihypertensives may lead to additive hypotensive effects. Always disclose melatonin use to prescribers.
Missed dose
If a dose is missed and it is still within 1–2 hours of the intended bedtime, it may be taken. If beyond that window, skip the missed dose and resume the regular schedule the following night. Do not double the dose. Consistency is key for circadian rhythm support, but occasional missed doses are not clinically significant.
Overdose
Symptoms of overdose may include severe drowsiness, confusion, disorientation, and hypothermia. There is no known antidote; treatment is supportive and symptomatic. Gastric lavage or activated charcoal may be considered if ingestion is recent. Seek immediate medical attention or contact a poison control center if overdose is suspected.
Storage
Store in a cool, dry place away from direct light and moisture. Keep the container tightly closed. Do not refrigerate unless specified by the manufacturer. Keep out of reach of children and pets. Discard after the expiration date printed on the packaging.

Always consult a qualified healthcare provider before starting any new supplement, especially if you have pre-existing medical conditions or are taking other medications. Individual results may vary.
Reviews
Clinical studies and user reports generally indicate favorable outcomes for sleep onset and jet lag management, with many users noting improved sleep quality without next-day grogginess. Some individuals report minimal effect, possibly due to variations in metabolism or underlying health conditions. Long-term efficacy data remains limited, and tolerance development is uncommon but possible. Always prioritize physician-guided use for chronic sleep issues.
