Q: What is Mello?

Mello is a personal-use melatonin diffuser that delivers the sleep aid each time you inhale - with you in control, with each breath you take (literally!).

Mello does NOT contain any of the following:

  • Nicotine
  • Tobacco
  • THC
  • CBD
  • Diacetyl

Q: How do I use Mello?

A: Inhaling through the mouthpiece will automatically activate the diffuser and turn the liquid melatonin inside into a fine mist which you inhale, then exhale after a brief moment. Inhaling melatonin ensures a quicker absorption time into the body as compared to ingestion/eating it, thereby achieving the same effect sooner.

Q: Why should I inhale melatonin instead of eating it?

The most common forms of melatonin are taken orally (eaten). The main issue with this method is that it will take some time for the melatonin to kick in - and depending on how much food and/or drink you had before, the effects may vary greatly. With Mello, as the melatonin is inhaled rather than ingested, the effects are much more consistent and predictable each and every time. Best of all - you won't have to wait as long!

Q: How many times should I inhale before bedtime?

The melatonin capacity in each Mello diffuser allows for approximately 300 inhales. We recommend inhaling 7-10 times before bedtime. Note that each Mello diffuser's useful life may vary depending on factors such as length of each inhale.

Q: How will I know when the device is out of melatonin and/or is finished?

  • When the light at the end of the device no longer lights up, or begins to flash on and off.
  • When there is no more vapor being produced when you inhale.
