The One Thing Every Laxative in Your Cabinet Was Never Designed to Do
And why thousands of women who'd "tried everything" say it's the only thing that finally worked.
You've tried the MiraLAX. The fiber. The probiotics. The senna that put you on the bathroom floor at 3am. The Linzess at $280 a month that faded after 5 weeks. The gallon of water your doctor swears is the answer.
Each one worked for a week. Maybe a month. Then it quietly stopped. And you were right back where you started. Three days. Five days. Longer. The pressure building by noon. The bloated belly by dinner. The straining that produces nothing.
And if you're a woman in your 40s or 50s, you probably remember when it started. It wasn't always like this. You were regular your whole life. Then perimenopause hit. The hot flashes. The sleep. The mood. And somewhere in there, your gut just… stopped.
Nobody connected the two. Your doctor handed you MiraLAX. Your friends said "eat more fiber." So you stopped talking about it. You half-accepted that this is just how your body works now.
It's not.
And the reason nothing in your cabinet has worked has nothing to do with the products themselves. It has to do with one thing they were all going around.
1 After Perimenopause, Your Colon Starts Pulling Out Too Much Water. That's Why Nothing Has Worked.
Your problem isn't fiber. It isn't probiotics. It isn't "drink more water."
It's a water problem. Inside your colon.
Your colon has one job: pull water out of your food before it leaves your body. When things move at a normal speed, it takes the right amount. Everything stays soft. You go naturally.
Then perimenopause changes the speed.
Your gut is full of hormone receptors. As estrogen and progesterone swing up and down through perimenopause — and then drop for good after menopause — the muscles that move things through your gut can slow down. It's one of the most common changes women report in their 40s and 50s. And one of the least talked about.
When things slow down, your colon has more time to do its job. So it does its job too well. Stress, sitting all day and certain medications just pile on top.
It pulls out too much water.
Your stool dries out. Hardens. Compacts. And once it's hard and dried out, it's stuck. Wedged inside a pipe with no moisture left to move it.
That's why you say "nothing moves" and "I feel like there's a rock inside me."
Here's the part nobody explained:
None of them get water back to the stool where your colon stripped it out.
One mineral does.
2 One Mineral Stays in Your Gut and Puts the Water Back.
In a third-party study conducted by Citruslabs, adults taking Lunor saw an 85% increase in bowel movement frequency within 7 days. 95% reported relief from constipation. Not our own in-house testing. An outside research company ran it.

Magnesium oxide barely absorbs. About 4% reaches your blood. The other 96% stays right there in your intestines.
And when it stays there, it does one thing: pulls water through your intestinal walls directly into the stool. Not around the hard mass. Through the walls. Into the dried-out stool.
The hard stool softens from the inside. The mass breaks apart. Your muscles move what's left gently. On their own.
This is not a stimulant laxative. It doesn't force anything. It doesn't flush. It doesn't stimulate receptors that fade. It puts back the water your colon took out.
3 Japanese Doctors Have Prescribed This for Over 100 Years. Your Doctor Never Mentioned It.
Walk into a doctor's office in Japan with constipation and you won't leave with MiraLAX. You won't leave with senna. You'll leave with magnesium oxide.
It's been used there for constipation for more than a century. Today it's the most prescribed constipation treatment in the country — given to an estimated 10 million patients every year.
It's a recommended treatment in Japan's own clinical guidelines for chronic constipation. And when Japanese researchers put it to the test in a randomized, placebo-controlled trial, patients taking magnesium oxide had more frequent bowel movements, softer stool and a better quality of life than the placebo group.
Ten million patients a year. Over a century of use. Tested against placebo.
Meanwhile, here, your doctor was stacking MiraLAX, then senna, then a $280-a-month prescription. Nobody told you the simplest answer was a mineral.
Then We Put Lunor to the Test.
Conducted by Citruslabs • Santa Monica, CA • January 2025
Citruslabs, a California research company, ran a 7-day study with 50 adults who struggle with constipation. Each participant took Lunor every night and reported their results on Day 1, Day 3 and Day 7.

4 No Fading. No Dependency. No Bigger Dose Next Month.
Here's what nobody warned you about the products in your cabinet: the more you use them, the more you need.
MiraLAX fades because your body adapts to polyethylene glycol. One capful becomes two. Two becomes three. The dose that worked in January does nothing by June.
Senna weakens the muscles it forces to contract. 1 pill becomes 2 becomes 4. The muscles get weaker. The dose gets higher. The cramps get worse.
Linzess stimulates receptors that downregulate after a few weeks. $280 a month. Fading by week 6.
And if you're in perimenopause or menopause, your body is already changing month to month. The last thing you need is a product you have to keep chasing.
Lunor works the opposite way.
Magnesium oxide draws water through osmosis. Osmosis is a law of chemistry. Your body does not build a tolerance to it. You never have to escalate. Same two capsules on day 1 and day 100.
Over time you may need it to do less — because once the dehydration cycle breaks, your colon starts doing more on its own.
Women who switch to Lunor feel a shift the first week and are still feeling it 6 months later. Because osmosis doesn't fade.
5 What the First 30 Days Actually Look Like.
Not a one-time flush. Not a MiraLAX day followed by 3 days of nothing. Your body relearning what it used to do automatically.
Study conducted by Citruslabs, Santa Monica. Commissioned by Lunor. Self-reported results.

6 One Ingredient. Nothing Hidden. Nothing Complicated.
You've tried the blends with 12 ingredients where you couldn't tell what was working. You've tried the protocols with 7 supplements lined up on the counter. You've tried the powders that taste like dirt and the gummies that are 50% sugar.
Lunor is one ingredient.
1400mg Magnesium Oxide per serving.
Third-party tested every batch. Capsule form — dissolves properly, not compressed tablets that pass through intact. No fillers. No binders. No proprietary blends. One line on the supplement facts panel.
Two capsules. Glass of water. Bedtime.
That's the whole routine. 30 seconds. Done.
7 It Won't Wreck You Like the Laxatives Did.
No 3am cramps. No "volcanic eruption." No racing to the bathroom. No shaking on the floor because the senna hit like a grenade.
Lunor doesn't force your muscles to contract against hard, dried-out stool. It softens the stool first. There's nothing hard to push against. Your muscles move the softened stool gently. On their own. The way they used to.
No cramping. No urgency. No dependency. No weakening your colon a little more with every dose.
Just your body doing what it was designed to do, once you give it back the water it was missing.
"But What If It Doesn't Work for Me?"
You've been burned before. Every bottle in your cabinet promised the same thing. So here's the honest answer.
Lunor works on one specific problem: stool that's dried out and hard because things have slowed down. For a lot of women whose constipation started around perimenopause, that's exactly what's going on.
But not all constipation is the same. Some women have a pelvic floor issue. Some have a medication side effect. Some have something else entirely.
If Lunor doesn't work for you, it means your constipation has a different root cause — and the 90-day guarantee means you risk nothing finding out. Try it for 90 days. If it doesn't work, email us and get every cent back. Even if the bottles are empty.
And if it doesn't work, that's worth knowing too. Take that to your doctor. You'll have ruled out the most common cause and saved yourself months of guessing.
If you have kidney problems or take prescription medications, check with your doctor before starting any magnesium supplement.
