Is melatonin addictive?

No. Melatonin does not cause physical or psychological dependence. It is not a sleeping pill in the classic sense, but a hormone that regulates sleep timing. The body does not 'get used to it' and does not reduce its own production when taking usual doses. With long-term use of high doses (>5 mg), a temporary decrease in receptor sensitivity is possible, which is why minimal effective doses are preferred.

When won't melatonin help with insomnia?

Melatonin does not help with most forms of chronic insomnia not related to a circadian rhythm shift. If you suffer from maintenance insomnia (waking up at night), anxiety-related insomnia, or psychophysiological insomnia — melatonin is largely ineffective. In such cases, CBT-I is needed.

Melatonin: A Guide to Proper Use

Melatonin is not a sleeping pill. It's a sleep timing regulator. When it works, what dose to take, and why more isn't better.

Melatonin is one of the best-selling sleep supplements. And one of the most frequently misused.

Most people take 5–10 mg before bed, wait for a hypnotic effect — and are disappointed. Because melatonin doesn't work that way.

1. What is Melatonin

Melatonin is a hormone produced by the pineal gland. It is produced in darkness and suppressed by light. Its function: to signal to the brain the onset of night and to "set" sleep time in the circadian clock. It is not a "sleep hormone" in the sense of a sedative — it is a "darkness hormone" or "time hormone".

2. When Melatonin Works

Melatonin is primarily effective for circadian rhythm shifts:

Jet lag — the best application. Take at your target sleep time in the new time zone
Night shift work — helps fall asleep at the right time
Delayed Sleep Phase Syndrome — see separate article
Restoring sleep patterns after disruption
In the elderly — melatonin production decreases with age

3. The Correct Dose: Less is More

Standard doses available (3–10 mg) are often excessive. Studies show: 0.5–1 mg is sufficient for most applications. Higher doses do not provide a better effect — but do cause side effects: morning grogginess, vivid dreams, suppression of endogenous production.

Recommended dose: start with 0.5–1 mg. If necessary, you can increase to 3 mg.

4. Correct Timing of Intake

This is critically important. Melatonin is not a "right before bed" sleep aid. For circadian shifts, take it 30–60 minutes before your desired sleep time. For jet lag — at your target sleep time in the new time zone, starting the day before your flight.

5. Melatonin vs. Sleeping Pills

Melatonin	Sleeping Pills (Z-drugs, benzodiazepines)
Time regulator, not a sleeping pill	Hypnotic effect
Does not cause dependence	Risk of dependence
Does not disrupt sleep architecture	May disrupt
Ineffective for chronic insomnia	Effective short-term
