This product is ideal for adults who struggle with falling asleep or staying asleep and prefer a non-habit-forming, plant-based solution.
The standout feature is Maizinol, which provides 6-MBOA, a compound naturally similar to melatonin. This helps decrease time to fall asleep and increase overall sleep duration.
