Sleep affects everything else in your day.

After a bad night, everything is harder. You lose focus at work, you get irritable, you crave sugar and you skip the gym. A few bad nights a week add up fast.

Focus
Slower thinking and more mistakes
Mood
Shorter temper, more stress
Energy
Afternoon crashes, more coffee
Recovery
Sore for longer after training

Fix your sleep and the rest of your day gets easier. That’s what the next 21 nights are for.

How it works

Why stress keeps you awake, and how reishi helps

At the end of a long day, your body is often still in work mode. Your heart rate stays up, your mind keeps running, and it takes a long time to fall asleep. When you do sleep, you spend less of the night in deep sleep, which is the stage that leaves you feeling rested.

Reishi contains triterpenes and beta-glucans that help your body calm down after stress. It doesn’t knock you out like a sleeping pill. It helps you wind down so sleep comes on its own.

In controlled studies, reishi extract increased total sleep time and deep sleep, and shortened the time it took to fall asleep (Cui et al., 2012; Chu et al., 2007).

Recovery Seltzer poured over ice

Why not just take melatonin?

Melatonin sets your body clock. It’s useful for jet lag, but in trials it helps people fall asleep only about 7 minutes faster (Ferracioli-Oda et al., 2013).
Reishi helps you wind down. Most bad nights come from stress. In controlled studies, reishi increased deep sleep without acting as a sedative.
No next-day grogginess. Reishi isn’t a hormone or a sleeping pill, and Recovery Seltzer has no caffeine.

What’s in your evening routine

The Sleep Kit combines reishi with two ingredients that have been tested in people.

reishiHelps you wind down

16:1 extract from the fruiting body, in both the capsules and the seltzer. Taken every evening to help your body calm down before bed.

Cui et al., 2012; Chu et al., 2007
magnesiumHelps your muscles relax

In a trial of 46 older adults, magnesium improved sleep efficiency, time to fall asleep and insomnia scores over 8 weeks.

Abbasi et al., 2012
chamomileA traditional bedtime herb

Chamomile contains apigenin, which acts on calming receptors in the brain. In a trial of older adults, chamomile extract improved sleep quality.

21NIGHTS

Try it on your own sleep, risk-free

If your sleep hasn’t improved, message us any time before night 21 for a full refund. Just send back what’s left.

Questions

How do I get my refund?

Message us any time before the 21 nights are up and send back whatever is left: unopened cans and your capsule bottle, even if it’s almost empty. We refund the full amount once it arrives.

I don’t have a sleep tracker. Can I still try it?

Yes. Rate each morning from 1 to 10 in your phone’s notes and compare week one with week three.

Will it make me drowsy the next morning?

No. Reishi isn’t a sedative, and Recovery Seltzer has no caffeine.

Can I take it with other medication?

Ask your doctor first, especially if you take blood thinners, blood pressure or blood sugar medication, or if you’re pregnant or breastfeeding.

Give it 21 nights. You have nothing to lose but bad sleep.
