Taking melatonin out of Thailand
Melatonin supplements may be exported from Thailand freely as a dietary supplement.
Details
Melatonin is an over-the-counter dietary supplement in Thailand and other jurisdictions (US, Canada, most of Asia) — freely exportable. Note that melatonin is a prescription-only medicine in some destinations (UK, EU generally, Australia, Japan), meaning arrival-side import may face restrictions even though departure is unrestricted. Personal-use quantities do not attract customs attention on departure.
