Each gummy delivers 5mg of melatonin, a hormone that helps regulate the sleep-wake cycle, and the recommended serving of two gummies provides 10mg per night. This product is ideal for anyone seeking a gentle, non-habit-forming aid to fall asleep faster and improve sleep quality, especially those who prefer gummy supplements over pills.
