Melatonin is sold as a food supplement as a food supplement in the United Kingdom, a separate category from a medicine. It has not been assessed by the MHRA and is not intended to treat or prevent any disease.

Pre-market effectiveness review does not apply to food supplements the way it does to licensed medicines, so review the label and ask a clinician if anything is unclear. Ingredients and dosing on the label are set by the manufacturer, not verified by the MHRA, so batch-to-batch consistency is not something any authority certifies here.
