This **melatonin** uses a MicroActive sustained-release delivery to keep levels up through the back half of the night — a 3mg dose that trickles out gradually rather than spiking and clearing within an hour, aimed at sleep maintenance and early-morning waking. At 3mg you're comfortably inside the 0.5-5mg clinical range, where melatonin has its strongest evidence for shortening the time it takes to drift off and steadying your circadian rhythm.
The sustained-release format is the point: rather than a single early spike that clears within a couple of hours, it aims to keep melatonin levels up through the back half of the night. Just know the evidence for it keeping you asleep is reasonable but more modest than the data on falling asleep. Take it 30-60 minutes before bed, as the label directs.
