Thread: Melatonin

It depends on whether you're taking the capsule form or the tablet form You ususally want to take the tablet form within 20 minutes of going to bed, and you want to take the capsule form within 2 hours of going to bed (Well that's what my bottles say at least). This is because it takes the capsule from longer to break down in your stomach Im guessing.
But look on the back of the bottle; it should say when to take it there.

I've only ever used the pills past 8:00pm. I don't know if they'll actually work in the afternoon, unless you're really tired already.

This is a natural chemical, so if you're not biologically set to sleep in the middle of day- you can't.
