Train Hard. Recover Harder.
Sleep can be the single most important thing you do every day to improve your focus & execution on a daily basis. Impossible Sleep is specifically formaulated to be your "off switch" for tonight so you can perform better tomorrow.
As Seen On
Built for Performance. Backed by Science
Built for elite athletes and high performers and backed by world-class research - Impossible Sleep is designed to not just help you get to sleep, but also help you perform better the next day.

Magnesium
A natural mineral the majority of people are under-supplement with. Encourages deep rest and recovery.

L-Theanine
An amino acid that has a natural "relaxing" effect. Dosed at just the correct amount to help "turn off" your brain and ease you into sleep.
What's Not Inside (and why)
Many sleep supplements pack their formulas full of ingredients so you think you're getting more bang for your buck. In truth, most are added at incorrect dosages and some ingredients shouldn't be there at all in the frist place.
Here's what's NOT in Impossible Sleep
Sugar - Spikes your blood sugar, keeps you wired and secretly in other formulas.
Melatonin - A hormone - not a mineral - and found in supra-physiological doses. Can interfere with your body's natural production. More on this here in: Why Melatonin is Bad For You (coming soon).
Valerian Root - Acts like a sedative, creates wild dreams, and about as effective as a placebo.
5-HTP - Helpful for stress relief, but not for sleep. Can have dangerous interactions with medications.
What People Are Saying
-
“I regularly started using magnesium about two years ago and it has done wonders for me. Started taking this and began to notice a greater calming effect. I'm assuming that's the L-theanine kicking in. Whatever it is, I love it. I give it a 10/10”
-
“Love how simple the formula is and has worked really well the last couple of weeks. Have been checking my REM and deep sleep with my Oura ring and seeing really solid sleep! Better than I’ve seen with some of the other teas and mixes I’ve tried.”

Why I Made This Sleep Drink
I created Impossible Sleep - because well...I was pretty bad at it. I found it hard to turn my brain off at night and wake up rested the next day. I wanted to make a clean, delicious sleep drink backed by science and tha's exactly what Impossible Sleep is!

Works but...
This product helps with sleeping but i do not like drinking 8 oz of water before i go to bed and then have to get up in the middle of the night to go to the bathroom - if you try to use less water with the mix it is EXTREMELY gritty and hard to choke down. I guess if you like drinking a lot of water for bed this product will work great.

Too early to tell!
I think Joels newsletter and other products are great ! I've tried this sleep aid powder for over a week and I actually feel / stimulated restless using it ?? I'm not saying it's a bad product without without any hard data - maybe I've got the dosage wrong ? BW SteveO


Impossibly Effective
I’m not quite sure how this works. I mean, I understand the ingredients and what they do; I’ve taken magnesium before bed for years now, and I even have a bottle of theanine right there on the counter… but this stuff somehow makes me almost instantly sleepier than almost anything I’ve tried (the exception being heroic doses of melatonin, which I only resort to when traveling). It actually tastes good (none of that too-much-stevia tang), and it works. If you’re trying to improve the quality of your sleep (and you should be), it’s worth a try. Worst case scenario, the tub is reusable ;) But seriously, this stuff works better than it has any right to.

Unexpectedly Effective...and Delicious
I've been focused on improving my sleep and I wanted to try a supplement so this product seemed like a good place to start. I THOUGHT it might take some consistent use to see any affects... I slept like a rock it and I actually slept through my sunrise lights that usually wake me up: two days in a row. Needless to say I kept using it and consistently felt a benefit in my sleep, which I track with my Oura ring, so it was both a feeling and data driven result. And it just tastes delicious so I'm always looking forward to this treat as part of my nightly routine.

didn't work for me
used it for 2 days. It didn't work for me. I track my sleep using an Oura ring. Numbers went down.
