Sublingual works well for melatonin!
Size: 60 Count (Pack of 1), Style: Melatonin 5mg
Sublingual seems to be the way to go with melatonin. It works well for me. It’s great this company offers a variety of doses. I was doing 10mg but I learned it might not good to stay on that high a dose for an extended period of time. So I switched to 5mg and it still works well.
