Full details
Melatonin is regulated by Singapore's Health Sciences Authority (HSA) as a Health Supplement. Personal-use quantities (typically up to a 3-month supply) may be brought into Singapore without an import licence, provided the product is properly labelled and not advertised for therapeutic claims requiring registration. Bulk quantities, prescription-strength formulations, or unlabelled products may be detained. Carry the original packaging.
Rare — Enforcement reported rarely.
Leaving Singapore with melatonin
Melatonin is an over-the-counter dietary supplement in Singapore 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.
Personal-quantity melatonin (OTC supplement) clears as routine in destinations where it is OTC. In prescription-only markets (e.g. UK, France, Germany), declare with prescription if asked.
