What makes Kinn different

Jujube seed

You'll know magnesium. You may know L-theanine. This one you won't.

Jujube seed has been used in Chinese medicine for two thousand years for the evening, and a mind that won't settle. A placebo-controlled trial of 106 women found a measurable difference in three weeks, at the 500mg we use.

The evidence behind jujube
  • 106women in a placebo-controlled trial
  • 500mgthe amount they took daily
  • 21 daysto a measurable difference
  • 2,000years of use

Mahmoudi et al., 2020. A double-blind, placebo-controlled trial of jujube seed at 500mg a day in 106 postmenopausal women. University-funded, no industry involvement.

Timeline

What to expect, and when

Six ingredients, working at different speeds.

Week one

The quick ones

L-theanine and glycine act on the night, not over weeks. Some notice early.

Month one

Jujube takes its time

Jujube seed is the patient one. Give it a month.

Twelve weeks

The skin takes longest

Collagen renews slowly. Months, not weeks.

Six months

Part of the evening

By now it's just what you have in the evening.

One Kinn, eight drinks.

Cold over ice or warm in a mug. Try a few and find your favourite.

Our standards

Every ingredient had to earn its place

Six made it in. Some obvious ones didn't.

In the UK it's a prescription medicine, not a supplement, so it was never an option for a nightly drink. It also does a narrower job than most people assume — it shifts the timing of your body clock, which is why it's prescribed for jet lag and shift work.

The one everyone expects, and it's in most products in this category. The evidence is reasonable for stress and thinner for anything else. It can also affect thyroid hormone levels, and thyroid conditions are more common in women, and more common again with age. Not a risk worth taking in a drink built for this group.

Magnesium always comes bound to something else, and that pairing decides how much you actually absorb. Oxide is the cheapest and by most estimates the worst absorbed by a distance — much of it simply stays in the gut, which is where its reputation for discomfort comes from. Bisglycinate absorbs considerably better and sits gently in the evening.

How we compare

You've probably tried a few of these.

"I already take magnesium."

Same form, same 250mg. Ours has five other things in with it.

"I already have a chamomile before bed."

A teabag gives you flavour. This gives you flavour and six ingredients at real doses.

"I already have one of the sleepy hot chocolates."

Those are built on ashwagandha. We left it out, because it can affect thyroid levels.

"I already take supplements before bed."

A drink at the point you'd pour a glass, not tablets on the way up.

The first thing I've swapped my wine for that I actually look forward to.

Tastes genuinely lovely — sharp lemon, not medicinal at all. I'd braced myself for something chalky and it isn't.

The ritual is the point. I make my cup, the house goes quiet, and it's become the ten minutes that are mine.

Took a few weeks before I'd have said anything. By week five I noticed I wasn't reaching for a third coffee.

One sachet is 20 calories, and there's no sugar in it. Mix it with soda water, slimline tonic, or just water.

A full refund, even if you've drunk it.

Kinn takes a few weeks before it's worth judging, so you get the whole plan to try. Thirty nights on the monthly, ninety on the quarterly.

Frequently asked questions

Think in weeks, not one night. It builds gradually with consistent use. Miss the odd night and you've undone nothing — but the same time each evening is what makes it add up.

When you sit down for the evening, instead of the glass you'd normally pour. There's no right time on the clock — the consistency matters more than the hour.

No. It takes the edge off, it won't knock you out. If you're expecting what two glasses of wine does, this isn't that — and I'd rather say so now than have you find out on night one.

No, and I'm not asking you to. But have it every evening if you can — most of what's in it builds up over weeks rather than working on the night, so having it now and then won't tell either of us much. Plenty of people will have it most evenings and still enjoy a glass of wine at the weekend.

Nothing to undo. Just pick it up the next evening. It's the pattern over a few weeks that matters, not any single night.

Check with your GP or pharmacist before you start. One of the ingredients, jujube seed, can interact with some antidepressants.

Kinn is a food supplement and contains no hormones. If you take any medication, have a quick word with your GP or pharmacist first, as you would with any new supplement.

Sharp Sicilian lemon, lightly sweet. It dissolves clear rather than clouding, and there's no chalkiness or aftertaste to get past.

No. You can buy a single box at £53, or subscribe at £42 a month and save. Skip, pause or cancel any time.

Magnesium is a sensible place to start, and it's one lever. But what you're after is rarely one thing — Kinn runs six, each with its own job. And the best formula is the one you keep taking: most don't fail in the lab, they fail in the cupboard three weeks in. A warm cup survives where a capsule doesn't.

You have as long as your plan — 30 nights on the monthly, 90 on the quarterly. Email us within that time and we'll refund you in full, including the sachets you've used. No forms, no returning half-empty boxes.
