Why you can't sleep on long flights. (It's not the seat.)
Airplane cabins are pressurized to the equivalent of 6,000–8,000 feet. So on a long flight your body is basically at a mountain resort, where oxygen levels are low. ALTISNOOZE is a melatonin-free bedtime drink mix made for sleep at altitude, so you can rest in the air and land ready to go.*

At 35,000 feet, your body thinks it's on a mountain.
The thinner, drier air in a pressurized cabin means less oxygen with every breath. That can disrupt your sleep the same way a first night at a ski resort does, even if you sleep fine at home. This often means:
Melatonin wasn't built for thin air. ALTISNOOZE was.
| ALTISNOOZE | Typical sleep aids | Altitude pills | |
|---|---|---|---|
| Supports oxygenation at altitude* | ✓ | ✕ | ✓ |
| Supports deep, restful sleep* | ✓ | ✓ | ✕ |
| No melatonin or morning grogginess | ✓ | ✕ | ✓ |
| Electrolytes for hydration | ✓ | ✕ | ✕ |
| No energizing herbs that keep you up | ✓ | ✓ | ✕ |
Sleep aids ignore the oxygen problem. Altitude supplements ignore sleep, and some keep you up. ALTISNOOZE supports both oxygenation and sleep.*

Questions
Can I bring it on a plane?
Yes. Each packet is a small single-serve powder sachet that goes right in your carry-on. Mix it with water once you're through security or onboard.
Will I be groggy when I land?
ALTISNOOZE has no melatonin and no drugs, so there's no sleeping-pill hangover. Most people wake up clear-headed.
Is it good for short flights?
It's made for long flights, where you actually want to sleep. For a short hop, we don't recommend it.
What does it taste like?
Berry. Just mix one packet into 4 oz of water and drink.
What if it doesn't work for me?
If ALTISNOOZE doesn't help you sleep better, email us within 30 days for a full refund. No need to send anything back.
Can I take it with medications or while pregnant?
Please check with your doctor first.
Your next long flight doesn't have to wreck you.
Pack ALTISNOOZE and land rested.
