★★★★★This is it
I managed a health food store for many years and tried different supplements and herbal teas… but THIS. This is it! Effective and hydrating to the colon.
End Of Season Sale⚡ Selling fast
The magnesium that never leaves the colon.It stays where the drying happens, brings the water with it, and mornings start happening on their own again.
Where the water actually goes
Your colon has one real job, and it does it to everything that passes through: it recovers water. That is why what leaves the body is drier than what went in. Slow the traffic down, for any reason at all, and that recovery keeps running on the same load. It keeps taking. What was soft becomes firm, then dry, then something your muscle can't shift.
Magnesium oxide is the one that stays in that room. Only about 4% of it is absorbed into the blood; the rest travels on and settles in the colon, where it draws water in from the surrounding tissue, into the hardened mass, until it softens. Your own muscle carries it from there. No nerve is fired and no muscle is ordered to squeeze. Your colon took the water out. Nothing you swallowed put it back.
In Japan this isn't a supplement-aisle idea. Magnesium oxide is what a doctor writes on the pad: around 10 million people take it, more than 4 billion tablets in a single year, and it has been the first thing reached for since the 1980s. Ask for it at an American pharmacy and you get a blank look and a shelf of fiber.
So the things you tried weren't wrong so much as aimed at the wrong half of the problem. That part is below.
Soft. Drying. Stuck.
The same stool at three points along the colon, and the only thing that changed between them is how much water is left in it. Fiber and stimulants were built for the first two. This was built for the third.
Why the cabinet kept letting you down
- Senna was built to make a muscle contract. It does that whether or not the load has any water in it, which is why it hurts, and why the amount you needed crept upward: a nerve that's shouted at every night stops listening.
- Fiber needs water to do anything. It swells. In a colon that has already taken the water out, it has nothing to swell into, so you got the bulk and kept the wait, and the bloating was the bulk.
- MiraLAX does bring water in, which is why the first weeks were good. Its own box says seven days. Nobody's mornings run on a seven-day calendar.
None of that was you failing at it. Each one was handed the wrong end of the problem.
Water follows salt. That's the whole trick.
Magnesium oxide holds its position in the colon and draws water in from the tissue around it, into the hardened mass, so it softens where it sits. Once it's soft, your own muscle carries it on the way it always did. Nothing forces. Nothing grips.
What the numbers actually say
70.6% improved. Thirty-three people, 28 days, randomized and double-blind against a placebo. On magnesium oxide, 70.6% improved; on the dummy capsule, 25%. The numbers first moved inside week one. Mori S, Tomita T, et al., J Neurogastroenterol Motil 2019;25(4):563-575.
96% stays put. In 2001 two researchers measured four kinds of magnesium sold in the US. Magnesium oxide came back at 4% absorbed. For any other magnesium that number is the disappointment. Here it's the entire reason it works. Firoz & Graber, Magnesium Research 2001;14(4):257-262.
It's in your own doctors' guideline. Magnesium oxide is named as an option in the 2023 AGA/ACG clinical practice guideline on constipation, published 19 May 2023 by American gastroenterologists. You were told everything looked normal. Nobody read you that page.
Said plainly: the trial gave 1,500mg a day, split into three doses, for 28 days. It did not test this bottle; it tested the mineral that's in it. A full serving here is four capsules, 1,400mg, printed on the panel and not folded into a blend. Two capsules is half a serving. That's where you start, not where you have to stay.
The trial, as the public record lists it
A 2019 trial of magnesium oxide, randomized, double-blind, against a placebo, exactly as Europe PMC records it. Look it up yourself; the listing is public.
Why two printed ingredients matter
Two things, both named.
Ozonated magnesium oxide and a small amount of citric acid drawn from tapioca, inside a vegetable capsule. Every quantity printed per serving, magnesium at 1,400mg per four capsules. No blend, no filler, no additive, no preservative, no stimulant. Two lines on the panel. Nothing to trace but those.
Built to stay.
Most magnesium is built to be absorbed. This one is built to stay. Only about 4% is absorbed; the rest travels on to the colon and draws water into what has dried out.
How to take it.
Two capsules and a tall glass of water, last thing before bed, a couple of hours after dinner. Start on two. Go to four only if you need them. Keep drinking water on the nights you take it; it needs something to draw on.
Checked, printed, made here.
Third-party tested, meaning a laboratory with no stake in it did the checking. Non-GMO Project Verified. Made in the USA. The full amount is printed, per serving, on the front.
What happens, morning by morning
The first morningSomebody should warn you and nobody does: this works while you're asleep, and morning one can arrive looser than you'd choose. That isn't the senna kind. Nothing is being forced; it's water turning up. Start on two capsules, and pick a night before a morning you aren't expected anywhere early.
Inside the first weekIn the trial, week one is where the numbers first moved. What that looks like at home: less effort, more warning, and a morning that's finished before the coffee is.
By four weeksThis is what the 70.6% looked like: less bloating, a waistband that's still where it was at breakfast, mornings that don't need the day planned around them. The trial counted a person as improved only if it held for at least two of the four weeks.
Month two onwardsTwo capsules at bedtime, on the nights you want the morning. 60 capsules at two a night is 30 nights, which is why most people take the two-month supply.
In their own words, a few weeks in

★★★★★★Knocks out bloating overnight
WaterBack is hands down the best cleanse I've ever tried because it completely knocks out bloating overnight without any awful cramping. You just take a few capsules before bed and wake up feeling lighter, totally cleaned out, and full of energy.

The things people ask before they order
What's in the capsule?
Ozonated magnesium oxides, providing 1,400mg of magnesium per four-capsule serving, plus natural citric acid from tapioca. The shell is vegetable cellulose with organic gum acacia. That's the entire list.
When do I take them, and does food matter?
Two capsules with a tall glass of water before bed, a couple of hours after dinner. Start on two; you can go up to four. Keep the water going.
How far does one bottle go?
60 capsules. At two a night that's 30 nights, which is why the two-month option is the one most people pick.
I've taken magnesium before and nothing happened. Why would this be different?
Glycinate and citrate are absorbed on purpose; that's what they're sold for, sleep and muscles, and they're in your blood long before they could reach the colon. Magnesium oxide mostly isn't absorbed. In the 2001 measurement of US magnesium products it came back at 4%, and that is the whole reason it reaches the place the others never do.
I drink a lot of water, so why is nothing moving?
Swallowed water is gone by the small intestine. Nothing you drink arrives where the drying happens. The magnesium does, and it brings water with it. Keep drinking on the nights you take it, so there's more to bring.
Fiber makes me worse, not better. What's going on?
Fiber needs water to work. In a colon that has already taken the water out, it has nothing to swell into, so it sits there as bulk, and bulk that isn't moving is what bloating feels like. This brings water first.
I'm on other medicines. Is that a problem?
It can be. Magnesium doesn't mix well with every prescription, and it's not something to guess at. Before your first night, run it past your doctor or pharmacist if you take any prescribed medicine or live with a diagnosed condition. If your kidneys are not what they were, that check is essential, and it matters more with every birthday. Adults 18 and over only. Pregnant or nursing: your doctor first.
Will it cramp me, or have me running?
Nothing in it tells a muscle to squeeze, and that's where cramp comes from. Water arrives, what was hard turns soft, and your own movement handles the rest. Because you take it at bedtime, the morning is where it shows, and the first one can be brisker than the ones after. Start on two, and pick a night before a day at home.
Does it wear off after a few weeks, the way the others did?
The trial scored people every week for four weeks and counted them improved only if it held for at least two of them; 70.6% did. Senna fades because it works through a nerve, and a nerve that's fired every night stops answering. Magnesium oxide doesn't go through a nerve at all.
Is it habit forming? Does my body get lazy on it?
It works by bringing water in, not by making a nerve fire. Your own muscle does the work; the magnesium only supplies the water. That's the difference from senna and cascara, the class linked to needing more over time. Skip a night whenever you want, and the refill stops with one email.
Shipping and refunds
Shipping is free to any US address, 5 to 9 days door to door, and you get a tracking link in your inbox as soon as it's on its way. If it turns out not to be for you, you have 90 days from the day it arrives: send one email to contact@krakensupps.com with your order number and every dollar you paid comes back.

★★★★★★Two pills, not four
I've only used my WaterBack maybe twice and was pleasantly pleased. I'm sensitive to things, so only used two pills vs. the four as suggested. Because of my job, I can't readily have access to a restroom so will use this more on the weekends for now.
One mineral. Two capsules. Ninety days to decide. The water goes back into what dried out, and the morning takes care of itself. If it doesn't, one email and every dollar comes back.
