It was never that you weren't drinking enough water.
Water you drink is absorbed high up, long before it reaches your colon — so it never gets to the part that dried out.
Magnesium oxide barely absorbs. About 96% stays in your gut, holding water where it's actually needed.
Two capsules before bed. No stimulants, nothing forced, nothing to cramp against.

90-day guarantee. Take it for 90 days. If your mornings haven't changed, email us and send the bottles back — used, empty, doesn't matter. Every dollar back. We'd rather refund you than have you add another bottle to the shoebox.
Two capsules before bed with a full glass of water. That's the whole routine — nothing to remember during the day, nothing to carry.
Take it at least two hours apart from any prescription medication. One bottle is 30 days.
If two loosens things more than you'd like, drop to one and stay there. Every capsule holds a real dose, so going down is as easy as staying put.
Sound familiar?
Nobody talks about this part. You just build a life around it — the two sizes up in the bottom drawer, the bathroom map of your commute, the box you buy every eighteen days. After a while you forget you built any of it.
And the advice never changes. More fiber. More water. All your tests are clear. Meanwhile the thing that's actually happening has never once been explained to you.
This is the part nobody explained.

350mg elemental magnesium per capsule. The form that stays in your gut rather than leaving it — about 96% of it never enters your bloodstream. Magnesium oxide has been used as a first-line option for chronic constipation in Japan since the 1980s.
Magnesium oxide has to be converted before your body can use it, and the thing that converts it is acid. Plain oxide leaves that step to your stomach. This doesn't.
A soluble fiber. Water on its own makes things loose — it doesn't make them formed. This is what gives what softens a shape to move.
Not a pressed tablet. Compressed tablets can pass through without fully breaking down — which is one reason a drugstore bottle of magnesium oxide often does nothing at all.
What to expect
Your colon isn't broken. It has one job — pull water back out of what's passing through — and when things slow down it has more time on the same material, so it takes out too much. What's left gets dry and hard, and the longer it sits the drier it gets. The loop doesn't level off. It tightens.
Something that took months to tighten doesn't unwind in a night. So here's what the ninety days actually look like, including the part most brands don't tell you.
This is where most people quit, and it's far too early. Two capsules before bed with a full glass of water — then leave it alone and don't read anything into the first few mornings.
Softer and easier to pass shows up before regular does. That's the first thing worth noticing, and it's the one people miss because they're staring at the calendar instead.
The effective dose varies a lot from person to person. If two capsules loosen things more than you want, drop to one and stay there. Every capsule holds a full dose, so going down is as easy as staying put.
This is the actual goal, and it's a strange one to aim at. Most people can't name the day it stopped being something they thought about — they only notice later that they'd stopped counting.

Two capsules. One glass of water. Ninety days to decide.

Glycinate & citrate
GUTORA
The difference
Glycinate is designed to be absorbed into your bloodstream — that's what makes it good for sleep and useless for this. Citrate absorbs around 30%. Both of them are gone before they reach the place that dried out.
Magnesium oxide absorbs about 4%. Roughly 96% of it stays right there in your gut, holding water where it's actually needed. That poor absorption isn't a flaw in the mineral. It's the entire reason it works.
Not around what dried out. Into it.

REVIEWED BY
GUTORA's formulation and educational content were reviewed by practicing physicians in gastroenterology and digestive health.
Board-Certified Gastroenterologist
The mechanism here isn't new or controversial. Osmotic agents have been the non-stimulant option for a long time, and magnesium oxide in particular has a long clinical history outside the United States.
What I'd want a patient to understand is the distinction between osmotic and stimulant approaches. Stimulant laxatives act on the bowel wall to force contraction. Osmotic agents don't act on nerve or muscle at all. That difference matters for anyone thinking about long-term use.
Chronic constipation should always be evaluated by a physician first to rule out anything structural.
Reviewed formulation and claims
Gastroenterologist
The question I hear most often is why magnesium didn't work. Almost always it's a form issue. Glycinate and citrate are formulated for absorption, which means they leave the gastrointestinal tract. Oxide is poorly absorbed, and for this particular purpose that's the useful property, not a drawback.
Conversion is the other half of it. Magnesium oxide requires gastric acid to become active in the gut, and reduced acid output is common with age and with long-term acid suppression. That's a reasonable thing for a formulation to account for.

Most of the patients I see with this have already done the fiber and the water. Those recommendations aren't wrong — they just address different variables than the one causing the problem.
A practical note: magnesium is not appropriate for everyone. Anyone with reduced kidney function, cardiac disease, an electrolyte disorder, or taking diuretics should not start this without speaking to their physician. And magnesium should be separated from other oral medications by a couple of hours.

Acid-activated magnesium oxide, in a capsule you take before bed. Magnesium oxide is the form that stays in your gut instead of being absorbed into your blood — about 96% of it — so it can hold water where it's actually needed. The citric acid is in there so the mineral doesn't have to rely on your own stomach acid to convert.
Two likely reasons. First, the form: glycinate and citrate are built to be absorbed into your bloodstream — that's what makes glycinate good for sleep and useless for this. Magnesium oxide absorbs about 4%. It stays. Second, conversion: magnesium oxide isn't soluble on its own and needs stomach acid to switch on. If you're past 45, on a daily acid reducer, or on a GLP-1, you may not have much. A drugstore oxide is usually a low-dose pressed tablet with nothing in the formula to help with that.
Two capsules before bed with a full glass of water. That's the whole routine — nothing to remember during the day, nothing to carry.
Take it at least two hours apart from any prescription medication. One bottle is 30 days.
Then take one. The effective dose for magnesium oxide varies a lot from person to person, and every capsule here holds a real dose rather than a fraction of one — so you can go down as easily as you can stay put. Your dose is whatever gives you a soft, formed result without loosening things more than you want.
Stimulant laxatives like senna and bisacodyl act directly on the nerves and muscle of the bowel wall to force contraction — that's the mechanism behind going from two tablets to four. Osmotic minerals don't act on nerve or muscle at all. There's no equivalent escalation mechanism. That said, if you've been on daily laxatives for years, talk to your doctor about how you come off them.
It isn't a stimulant, so it doesn't force your muscles to squeeze against anything. Cramping with senna or Dulcolax comes from exactly that — soft tissue gripping something hard and dry. Magnesium doesn't act on nerve or muscle at all. If two capsules loosen things more than you'd like, drop to one and stay there.
Some people notice within a couple of days. Plenty of people get nothing in week one and are still finding their dose — that's the most common reason someone quits too early. Give it a week before you judge it, and two months before you decide it isn't for you.
Space it at least two hours from other oral medication. Magnesium can interfere with the absorption of some, including certain antibiotics and thyroid medication. If you're on a daily prescription, check with your pharmacist first — they'll know your list.
Anyone with reduced kidney function, heart disease, an electrolyte disorder, or taking diuretics should speak with a doctor before starting — magnesium clearance depends on your kidneys. Not for use during pregnancy or breastfeeding without medical advice. And persistent constipation, blood in stool, unexplained weight loss, or a sudden change in bowel habits should be looked at by a physician, not managed with a supplement.
