A two-part night formula for people over 55 who are sick of lying awake, sick of waking at 2 a.m., and sick of feeling half-asleep by mid-afternoon.
Most sleep products are built to knock you out. This one is built to get you into the deep, unbroken sleep your body actually needs, and keep you there. Two bottles, taken together before bed - and the second one, Koru Advanced Magnesium, comes free with every pack. Made in Rangiora.

Here's the thing nobody tells you. These are not six separate problems. They are one problem. Your sleep isn't deep enough anymore, and it hasn't been for a while.
Three things, in this order.
Without the drugged, heavy feeling. Passion flower and L-theanine settle the mind so you're not lying there running through tomorrow.
This is the part most products miss. 5-HTP and active B6 give your body what it needs to make its own melatonin through the night, and valerian helps you stay under instead of surfacing at 2 a.m.
Properly absorbed magnesium, formulated for the over-55 body, so the sleep you get is the restorative kind. Not just unconscious. Actually asleep. That's the job of your free bottle of Advanced Magnesium.
That's the sleep promise. Now here's why the third part matters more than you think.
Every organ in your body is plumbed into the lymphatic system, which carries away the day's waste. Except your brain. Your brain has no drain of its own. So it cleans itself, and it does it while you're in deep sleep.

For most of a century nobody could say how the brain got clean. It sits inside a sealed case, packed tight, with no room for the plumbing every other organ gets. Then in 2012 a research team, watching living brains through a new imaging technique, found the answer hiding in plain sight: a network of channels running alongside the brain's blood vessels, carrying cerebrospinal fluid deep into the tissue. They named it the glymphatic system. We call it the nightly clean-out.
The follow-up work, a year later, is the part that matters for your sleep. Watched cell by cell in animals, the system barely ran during waking hours. But during sleep the gaps between brain cells opened up, by as much as 60%, fluid flowed in along the channels, and the day's metabolic waste washed out roughly twice as fast as it did in the waking brain. The brain doesn't clean itself around the clock. It waits until you're under.

In 2019 scientists put sleeping volunteers into an MRI scanner and watched the same thing happen in humans, in real time. Every twenty seconds or so a big, slow brainwave rolled through - the signature of deep, slow-wave sleep - and right behind each wave came a pulse of cerebrospinal fluid, washing through the brain like a slow tide. Wave, then rinse. Wave, then rinse. All night.
Awake, the pulses all but stop. In light, broken sleep they're weak. It's the deep, slow waves that drive the pump. Which is why a night of shallow, drugged sleep doesn't finish the job, no matter how many hours you were technically unconscious.

Here's what changes with age. The deep, slow-wave stage of sleep drops away sharply after 60. You can still be in bed for eight hours, but far less of it is the deep kind. So the clean-out gets cut short. Whatever didn't get cleared last night is still sitting there this morning, and by three o'clock you've piled a whole day on top of it.
That is the afternoon fog. That is the room you walked into for no reason. It was never your memory. It was your plumbing.
You don't see the soot building up. Nothing looks any different day to day. But leave it long enough and one day you've got a real problem. Your brain works the same way. Which is why the clean-out matters even on the nights you feel like you slept fine.
"Sleep isn't rest. It's the nightly clean-out."

A sleeping tablet gets you unconscious. So does a big dose of melatonin. But the clean-out doesn't care whether you're unconscious. It cares whether you're deep. Something that drops you into shallow, drugged sleep and leaves you groggy at seven in the morning hasn't fixed anything. It's moved the problem to breakfast.
Plain magnesium usually doesn't do it either. Most of what's on the shelf is magnesium oxide, which is cheap and barely absorbed, and after 55 your gut absorbs less of it again. You take it, feel nothing, and decide magnesium doesn't work for you. It probably never got in.
Good sleep has three jobs. Get there. Stay there. Go deep enough to finish. Almost nothing on the shelf does all three. So we built two products that do.
Sleep gets you there. Magnesium makes it count. Take them together, and let your body get on with the job.
Three steps. No prescriptions, no appointments, no risk.
One, two or four bottles of Koru Sleep - every bottle comes with a free bottle of Advanced Magnesium. Free delivery on orders over $100.
Two Koru Sleep and two Advanced Magnesium, together, with a glass of water about 45 minutes before bed. Keep both bottles on the bedside table.
Easier sleep often comes in the first week; deeper sleep and clearer afternoons take three to four. Your guarantee runs a full 60 days either way.
Most people find they get off to sleep more easily and wake less. Some feel it on night one. For others it takes a week or so. Don't judge it on the first night.
Sleep starts to feel more solid. The 2 a.m. wake-ups get further apart. Mornings feel clearer than they have in a while.
This is where the magnesium has really built up and the deep sleep is doing its work. Muscles settle. The afternoon slump lifts because the night is finally doing its job. This is also why we give you 60 days and not 30.

This is not a sedative. It won't flatten you. It supports the sleep your body is already trying to get, which is exactly the sleep the clean-out needs.
We're Koru Nutrition, from Rangiora in North Canterbury. We make every one of them ourselves, in our own facility, in controlled batches. That's why over 500 pharmacies across New Zealand put us on their shelves. Everything we make is built for people over 55, because that's who walks into a pharmacy and asks for us.

"Prior to taking this product I had poor sleep patterns: often taking a while to get off to sleep and the same if had to get up to use the toilet. Now I get off to sleep easily and wake refreshed, less irritable and more focused."
"For years I've struggled to get more than 3-4 hrs per night. I now sleep most of the night, and wake, refreshed, and alert. Thank you, Koru Nutrition."
"Koru Sleep is excellent I have been taking this nightly for some time now and I sleep soundly and relaxing and wake up refreshed at 5.30am each morning, so my Body Clock is working well and I love being up early as its the best part of the day."
We would rather lose the sale than have this be wrong for you.
If none of that is you, carry on.
Two Koru Sleep and two Advanced Magnesium, together, with a glass of water about 45 minutes before bed. One habit, one moment.
It's designed so you won't be. The sleep signal comes from what your body makes, not a dose still sitting in your system at 7 a.m.
No. Drop it while you're on this. You don't need two, and the bottle in your pack is the better-absorbed form anyway.
Falling asleep more easily, often within the first week. Deeper sleep and clearer afternoons, give it three to four weeks. That's why the guarantee is 60 days.
Because the jobs are different. Cramming a proper dose of magnesium into the same capsule as the sleep herbs would mean short-changing both. Two bottles means both are done properly - which is why the magnesium comes in your pack as its own full bottle, free.
60 day money back guarantee. No arguments. Email or ring us in Rangiora and we'll sort it.
Every bottle of Koru Sleep (60 capsules) comes with a free bottle of Koru Advanced Magnesium (60 capsules, worth $34.99) - one for one, so the whole pack works as a pair. Free delivery on orders over $100.



Try it for 60 days. If you're not sleeping better and waking clearer, send it back, empty bottles and all, and we'll refund you in full.
You won't feel the clean-out happening. You'll only feel it when it hasn't. The foggy afternoons. The room you walked into for no reason. The eight hours that didn't count.
Give your body a deep enough night to finish the job. Made in Rangiora. Backed by science. Built for you.
