The ceremony of sleep.
The moon has always known.
Not a sleep supplement. A ceremony.

You fall asleep fine.
It's 3am that's the problem.
The wake. The ceiling. The calculation.
The version of you that appears at 3am and will not leave.
Serune is a dark cacao, cherry and vanilla ritual drink. Warm. Precise. Dissolved at 9pm into hot water — or any milk of your choosing. Seven precisely dosed active ingredients. One sachet. No melatonin.
The problem
The problem has a name.
Most sleep products were built for the wrong moment. You don't need help getting to sleep. You need to stay there.
The wake at 3am. The thoughts that arrive the moment they're least welcome — the email you forgot, the thing you said years ago, the loop with no exit. Then the calculation: if I fall asleep now, I'll still get four hours.
Then four becomes three.
The body gets out of bed. The mind got out much earlier.
That exhaustion is not tiredness. Tiredness lifts. This is the kind that sits behind your eyes and follows you into every room.
Melatonin gets you down. It doesn't keep you there. And the morning after melatonin has its own name: the grogginess. That slow, cotton-headed hour that makes a bad night feel like two.
The sleep category was built for the person who cannot fall asleep.
You fall asleep fine.
Serune was built for what happens after.
The formula
Read the label before you buy anything. We agree. So here is the label.
Every active ingredient in Serune is a mineral, amino acid, or plant extract. No synthetic hormones. No melatonin. No proprietary blends. Every dose is set at the amount used in published research.
Glycine
3,000mg
The ingredient that tells your body the night has begun. At therapeutic dose — not token, therapeutic — it helps lower your core temperature: the signal your body needs to move into deep, sustained sleep. This is the mechanism behind the 3am wake. This is where the formula starts.
Magnesium bisglycinate
150mg elemental
The magnesium your body can actually use. Bound to glycine (chelated) — rather than the oxide form that passes largely unused. Contributes to normal nervous system function and the reduction of tiredness and fatigue.* The difference between taking magnesium and feeling it.
L-Theanine
200mg
The amino acid in green tea that makes it feel nothing like coffee. It doesn't sedate — it quiets. The mental noise that follows you to bed — this is what it's for. Calm but present. Relaxed but not gone. Confirmed effective at this dose in a 2025 meta-analysis.
KSM-66 Ashwagandha
300mg
For the body that won't switch off. The cortisol that stays elevated long after you've stopped asking it to. The most clinically studied ashwagandha extract in existence — over 20 published human trials. Not for falling asleep. For the part of you that forgets how.
Chamomile extract
250mg (1.2% apigenin)
Not tea. A standardised extract — measurable, consistent, not a gesture. Apigenin binds to GABA receptors: your nervous system's off switch. The same compound in Beam Dream, the most-reviewed sleep drink in the US. The difference: we left out the melatonin that generates their most common complaint.
Vitamin B6 (as P-5-P)
2.8mg (200% NRV)
The form your body uses directly, without having to convert it first. Contributes to the regulation of hormonal activity.* The ingredient that works quietly in the background so everything else works better.
Zinc citrate
10mg elemental
Contributes to normal cognitive function.* So that tomorrow — the version of you that has to function, to think, to show up — is actually possible.
* Authorised EU/UK health claim. All other statements are factual descriptions of ingredient mechanisms based on published research.
No melatonin. No proprietary blends. You can read the full ingredient list and look up every one before you buy.
That is deliberate.
The ritual
At 9pm, most people are still in their day.
Serune is permission to leave it.
Dissolve one sachet into hot water — or any milk of your choosing. Watch it darken. Sit somewhere you actually like sitting.
This is the beginning of the night. Not the end of the day.
The ritual matters as much as the formula. Habit cues are powerful physiological signals. Doing the same thing at the same hour each night is not just pleasant — it is functional. Your body starts to understand what's coming before you've finished the mug.
That is not placebo. That is circadian biology.
Why not melatonin
Why no melatonin.
Melatonin is a hormone.
Your body makes it. Take it externally, night after night, and your body learns to make less of its own. The most common complaint from melatonin products is not that they don't work.
It's the morning. The grogginess. That slow, cotton-headed hour that makes a bad night feel like two.
Serune contains zero melatonin. Every active ingredient is non-hormonal. The formula does not override your body's architecture. It supports it. Works with the mechanisms your body already knows how to run — and gives them what they need to run properly.
No melatonin. No morning fog. No dependency. No guesswork.
Built to a standard
The formula is built on published research. Every active ingredient is pharmaceutical or food-grade. The health claims on pack are EFSA-authorised — meaning they have passed the European Union's independent scientific review. Not internal review. Independent.
We are not launching until the formula, the packaging, and the experience are exactly right. Right now, we are building a small group of women who want to be first.
