Better sleep isn't being knocked out.
Sedatives force you down and you pay for it in the morning. Sleep does the opposite — it lowers the barrier to your own sleep, then gets out of the way.
Recovery happens while you're asleep.
The training, the protein, the work — none of it lands without sleep. It's the window your body uses to repair, and the one most people shortchange. Sleep helps you protect it.
You drift back off instead of staring at the ceiling for an hour.
Body exhausted, mind racing — the racing finally slows down.
You wake up clear and ready, not fighting through fog.
Sleep deep, recover, show up. Skimp on sleep and everything else gets harder — and that's where the results actually live.
Sleep supports a calmer wind-down and deeper rest — without added melatonin or sedation.
What's inside Sleep.
Five calming ingredients that lower the barrier to sleep — no synthetic melatonin, no sedative hangover. One scoop in water, 1–2 hours before bed.
The gentle, well-absorbed form (200mg elemental) that calms the nervous system without the GI mess.
Quiets mental chatter and supports a calm, steady drift into sleep.
A clinically studied adaptogen that lowers the cortisol response that keeps you wired at night.
An amino acid that lowers your core body temperature to cue sleep — studied at 3g to help you fall asleep faster and wake clearer.
A natural compound (from chamomile) that supports calm and an easier drift into sleep.
Deeper sleep, without the grog.
One scoop, 1–2 hours before bed.
Mix one scoop into water as you start winding down — not as you turn the light off. Let it work with your routine: dark room, cool temp, no doom-scrolling. The drink supports the habit; it doesn't replace it.
Calm the mind, relax the body.
Theanine quiets mental chatter, magnesium relaxes the nervous system, ashwagandha lowers the stress response, and glycine plus apigenin round it out — glycine even nudges your core temperature down to cue sleep. Five levers, no synthetic hormone dump.
No added melatonin. No mystery dust.
Most sleep aids lean on a synthetic melatonin megadose (which leaves you groggy and your body down-regulates) or hide doses in a 'nighttime blend.' We use studied ingredients at real doses, printed on the front — no synthetic hormone dump.
Sleep vs. the melatonin gummy.
Real wind-down support — without the synthetic hormone, the grog, or the down-regulation.
Tonight, and over the weeks.
Most people feel calmer the first night — and ashwagandha's stress support compounds the longer you stay on. Individual results vary.
The edge comes off.
Theanine and magnesium start to quiet the mind and relax the body before your head hits the pillow.
You drift, not fight.
Apigenin and glycine help lower the barrier to sleep — glycine nudges your core temperature down — so you fall off faster instead of lying there running the day back.
Clear, not foggy.
No synthetic melatonin means no hangover — you wake up ready instead of snoozing through the grog.
Stress settles.
Ashwagandha's effect on the stress response builds over a few weeks — winding down gets easier the longer you stay on.

How and when do I take it?
One scoop in water 1–2 hours before bed, as you start winding down. Pair it with good sleep hygiene — dark, cool room, off your phone — and let it support the habit.
Wait — is there melatonin in it or not?
No added synthetic melatonin — none of the 3–10mg pills that leave you groggy and that your body can down-regulate. Sleep leans on studied, non-hormonal ingredients — magnesium, glycine, theanine, ashwagandha, and apigenin — so you get the wind-down without the hormone hangover.
Will I wake up groggy?
That's the whole point of leaving synthetic melatonin out. Sleep is built to help you fall asleep and sleep deeper, then let you wake up clear — not foggy.
What does the glycine do?
Glycine is an amino acid that gently lowers your core body temperature — one of the physical signals that tells your body it's time to sleep. In studies, about 3g before bed helped people fall asleep faster and feel clearer the next morning. It's a big, well-studied lever most sleep formulas skip.
Is it habit-forming?
No. None of the ingredients are sedatives or hormones you build a dependency on. You can take it nightly or only when you need it.
Why magnesium glycinate specifically?
Glycinate (magnesium bound to glycine) is the calm, well-absorbed form. Cheaper products use magnesium oxide, which is poorly absorbed and more likely to upset your stomach than help you sleep.
Why a drink instead of capsules?
Because the effective doses don't fit in a couple of capsules — 3g of glycine alone would be six-plus pills. A drink mix delivers the full doses and doubles as a wind-down ritual: make it, sip it, start powering down. The format is part of what makes it work.
Does ashwagandha need to build up?
Theanine, magnesium, glycine, and apigenin work the same night. Ashwagandha's effect on the stress response tends to build over a couple of weeks of consistent use.
