A Korean sleep ritual · melatonin-free

Jalja.It means goodnight.

잘 자 · JAHL-jah — the soft, affectionate way to say sleep well.

A nightly drink for the mind that won't quit at 11:47pm. Saffron and wild jujube seed, every ingredient at a studied dose — and not one milligram of melatonin.

The real beauty sleep

Everyone's selling beauty sleep. We just make the sleep.

Collagen to sip, serums to wear to bed, silk masks — a whole aisle promising beauty while you sleep. Here's the quiet part: the thing that actually makes you feel and look better was never the product. It's the sleep itself. Jalja doesn't add beauty to your night. It makes the night real.

So we kept the one good habit skincare taught us — know your actives, respect the dose, stay consistent — and pointed it at sleep. Call it the skincare of sleep: not a knockout pill, a nightly regimen.

  • Feel it tonight

    Glycine, magnesium and theanine for the wind-down you notice the very first night.

  • Changes over weeks

    Saffron and wild jujube build with consistent nightly use — like any active worth using.

  • Just sleep

    No skin claims, no gimmick. The most honest beauty routine there is — a real night's rest.

The promise

Everything on the label. Nothing hidden behind it.

Most sleep supplements hide their doses inside a "proprietary blend," then sprinkle in trendy ingredients at a fraction of what the research used — enough to print on the front, not enough to work. We don't. Every ingredient is named, dosed in the open, and chosen to earn its place.

  • Studied doses

    Each active in line with the amount used in sleep research — not a dusting for the label.

  • No proprietary blends

    Every milligram disclosed. The plant part and the Latin name, right there to read.

  • Melatonin-free

    No hormone, no morning fog. Built for nightly use and a clear head at sunrise.

What's inside

Six ingredients. Every dose in daylight.

The sleep research on jujube is on the seed, not the fruit — so that's what we use. And five of these six are dosed to the research; one, inositol, we include because we love it and it's gentle — and we say so. We'll always tell you which is which.

What we left out — and why

The honest part most brands skip.

A formula is shaped as much by what you refuse as by what you add. Here's what didn't make it, and the reason:

  • Melatonin

    A hormone that can leave you foggy in the morning. We wanted something you take every night and still wake up clear.

  • Tart cherry

    Its sleep angle is really just trace melatonin — and you'd need an impractical amount. Not for us.

  • Isolated apigenin

    Trendy right now, but the isolated dose isn't well studied. We don't add things just because they're having a moment.

Who it's for

For people who've been tired since 2019.

  • The 2am mind

    Whose thoughts get louder the moment the lights go out.

  • The change

    Perimenopause rewrote your sleep. Your sleep aid should keep up.

  • The recoverers

    Who treat sleep as training and won't touch a morning hangover.

From the founder

I almost added more. Then I checked.

I started this because I was tired — the kind that doesn't go away — and every sleep product I tried either knocked me out and left me foggy, or did nothing at all. So I went deep. I read the studies. I tested on myself, night after night.

The hardest part wasn't finding ingredients. It was leaving them out. Every time I wanted to add something because it sounded good, I made myself ask: is there real evidence, at a real dose? If not, it didn't go in — no matter how trendy. There's exactly one ingredient I kept on a feeling instead of a study, and I'll always tell you which one and why, because you deserve to know the difference.

That's the whole promise. Everything shown. Nothing hidden. The last kind word of your day.
