Circadin, helps you sleep the way you’re supposed to

Melatonin is a hormone produced in your body that plays a role in sleep, and as we age we produce less melatonin.

Circadin works with your body’s natural sleep rhythm by releasing melatonin gradually over 8-10 hours from when it is taken – and that’s what makes Circadin different to other products.

Circadin can help you fall asleep easily and sleep soundly, allowing you to wake feeling refreshed and ready to face the day.
