The shot worked. The food noise went quiet, the weight came off, the dress zipped again. Then somewhere around week ten, your gut started slowing down.
Every other day. Then every three. Then a capful of MiraLAX in your coffee, because that's what your doctor said to do. Then magnesium on the weekends, a suppository, maybe Linzess. By 6pm your stomach looks five months pregnant, even though the scale says you're down twenty pounds. Your doctor calls it a common side effect and tells you to drink more water.
And you're stuck. Stop the shot and the weight comes back. Stay on it and your gut stops working. Nobody has offered you a third option.
There is one, and you don't have to give anything up for it. Here's what the drug is actually doing to your gut, and why women on GLP-1s are adding one sachet in a glass of water with dinner and keeping their medication exactly as prescribed.
The shot slows your whole gut, not just your stomach.
GLP-1 medications quiet your appetite by slowing down how fast your stomach empties. Food sits longer, you feel full longer, you eat less. That's the medicine working. But the slowdown doesn't politely stop at your stomach. It runs the full length of your gut, all the way down to the colon. That's why constipation is one of the most common side effects people report on these drugs.
A slower colon has more time to pull water back out of the stool, so it dries, hardens and packs down. Then MiraLAX pours loose water in from the top. Loose water takes the easy path. It runs around the hard, dried stool, not into it. You get urgent, watery mornings and still feel like you never finished, and one capful quietly becomes two.
The fiber in the sachet works the other way. It dissolves completely and travels with the stool as it forms, holding water inside it, so the stool softens from within and moves on its own. Nothing gets forced, and nothing gets flushed past.
“Down 26 pounds and going once a week with two capfuls of MiraLAX. Ten days after I started the sachet at dinner I went on my own, before work, with nothing else. Same Wegovy dose.”
Tammy W., Georgia
You're eating less, so the crew that runs your colon is starving.
Your colon doesn't decide to move by itself. It waits for a signal. Billions of bacteria living in it, Bifidobacteria and the strains that make butyrate, eat the fiber left over from your meals and turn it into that signal. Butyrate keeps the colon lining healthy and tells the muscle in the wall to squeeze and push.
Now look at what you're eating. Half a dinner. A few bites at lunch. Some days no breakfast at all. Smaller meals arriving slower means far less food reaching that crew. They start to starve, the signal fades, and the colon slows down even more. Then every laxative flush rinses out the few that are left. Your doctor charts it as "managed with OTC." Your gut is starving.
The sachet puts the food back. Sunfiber® is a prebiotic fiber that feeds the crew so they can make butyrate again, even while your medication keeps everything slow. And 8 billion CFU of Bifidobacterium lactis adds workers back while there's finally something for them to eat. Fed, not flushed.
“I was eating 900 calories a day on Mounjaro and buying expensive probiotics that did nothing. Nobody told me there was nothing left for them to eat. This is the first thing that actually changed my mornings.”

Your small GLP-1 dinner never fully breaks down. It sits in you all night.
Here's the part most doctors never connect. On a GLP-1, even a small dinner sits in a slowed-down stomach for hours. It reaches the gut half-processed, then sits there overnight while you sleep. The protein, the fat, the starch, the cheese: half-digested and fermenting until morning. That's the 6pm bloat, the sulfur burps, the heavy pressure at 2am, and the "I'm still full from last night" feeling at breakfast.
A morning laxative can't touch any of this. By 7am the fermenting is done, and all a capful can do is push out what never broke down. That's why the sachet goes in a glass of water with dinner, not with your coffee. Five DigeZyme® digestive enzymes (amylase, protease, lipase, cellulase and lactase) help break that meal down at the table, a little fennel settles the gas, and the fiber goes to work on the night shift.
About the first few nights: start with half a sachet for the first 4 nights, then move to a full one, so a sensitive GLP-1 stomach eases into the fiber. If you've been using a laxative, your colon may need a night or two to remember it doesn't have to be forced. Most women notice the first softer, easier morning around day 2 or 3. Night two is where most people give up. Keep going.
“I'd eat four bites of chicken and look pregnant by 6. I thought that was just the Ozempic. Within a week of taking it with dinner the evening bloat was gone, and the sulfur burps stopped too.”
Jennifer K., Ohio
It's the fiber that won't make a full GLP-1 stomach feel fuller.
If you tried Metamucil on a GLP-1 and felt worse, you weren't imagining it. Psyllium swells into a thick gel and ferments fast. Inulin and chicory root in fiber gummies ferment even faster. In a stomach that's already slow and a gut that's already backed up, that means more fullness, more gas, and sometimes more nausea. Bulk fiber adds cargo to a gut with nobody left to move it.
Partially hydrolyzed guar fiber (Sunfiber®) is a different kind entirely. It dissolves clear, with no grit and no sludge, and gut bacteria ferment it slowly, so it doesn't balloon. It was developed in Japan and has been used for decades in hospital and tube-feeding nutrition, for patients who eat very little and can't afford cramps or urgency. Each sachet has 6g of it.
And it's been studied. A review of 7 studies and 325 people found it significantly increased how often people went, an effect the authors described as similar in size to laxatives. In adults with chronic constipation, four weeks of it shortened colon transit time and cut straining, pain and the number of days people reached for a laxative.
Sources: Kapoor et al., 2017, systematic review and meta-analysis · Polymeros et al., 2014 · randomized trial in older adults, 2022. Studies used partially hydrolyzed guar gum, not this product, and were not in people taking GLP-1 medications.
“Metamucil on Zepbound made me feel like I'd eaten a brick. I almost didn't try this because it said fiber. It dissolved clear, tastes like light fruit, and I didn't feel any fuller after dinner.”
Michelle P., Colorado
You don't have to choose between the weight loss and your gut.
Most women in this spot think there are only two doors. Stop the medication and watch the weight come back, which research shows happens to most people within a year of stopping. Or stay on it and keep stacking MiraLAX, magnesium, suppositories and Linzess while the dose of everything climbs.
The third door is simpler. Keep taking your GLP-1 exactly as prescribed. Feed what it starved. There's nothing in the sachet that forces anything: no senna, no cascara, no stimulant laxative. Fiber that holds water and feeds the crew, a probiotic, enzymes and fennel. Nothing for your body to build a tolerance to, so the same sachet works on day 1 and day 100, at any dose of your shot.
It's a few grams of fiber in a glass of water, with no sugar, so it fits even the smallest GLP-1 dinner. Most women are tapering off their laxatives somewhere between week 2 and week 6, still on their medication, still at their goal weight.
“I was ready to quit Ozempic because I couldn't live like that. Six weeks later I'm off the MiraLAX and the Linzess, still on my 1mg, still 31 pounds down. I went out for pasta last Friday and didn't think about it once.”

| How it works | On a slowed GLP-1 gut | Feeds your gut bacteria? | Helps dinner break down? | Typical cost | |
|---|---|---|---|---|---|
| MiraLAX | Pulls loose water into the colon, which runs around hard stool | Urgent, watery, never finished. Dose often climbs | No, flushes it out | No | ~$15–25/mo |
| Psyllium (Metamucil) | Swells and adds bulk | More fullness, gas, sometimes nausea | Ferments fast | No | ~$10–20/mo |
| Magnesium, suppositories | Pulls water in or forces a movement | Rescue only, cramping common | No | No | ~$10–20/mo |
| Linzess | Prescription that triggers gut receptors | Diarrhea or pain possible, some report it wearing off | No | No | Hundreds without coverage |
| Probiotic alone | Adds bacteria | Little to eat on small meals | Adds them, doesn't feed them | No | ~$30–60/mo |
| One sachet at dinner | Holds water inside the stool, feeds the crew, helps dinner break down | No stimulant, nothing to build a tolerance to | Yes, prebiotic + probiotic | Yes, 5 enzymes | From $0.92/day |

Check the label for these 5 things
On a GLP-1, a product that misses even one of these is working on half the problem. Drugstore fiber is psyllium or inulin, probiotic powders have no fiber, and almost none have enzymes for the meal itself.
- ✓A soluble fiber that dissolves completely. Partially hydrolyzed guar (PHGG), not psyllium, not inulin.
- ✓A probiotic to put the crew back.
- ✓Digestive enzymes for the meal itself, so a slow-moving dinner breaks down instead of fermenting overnight.
- ✓No senna, cascara or stimulant laxatives of any kind.
- ✓Taken with dinner, the meal your medication leaves sitting longest.
What the first 6 weeks usually look like on a GLP-1
- Nights 1–4
Half a sachet with dinner. Nothing dramatic, and that's the point: no cramps, no urgent morning. Take your shot on its usual schedule.
- Day 2–3
A gentle signal in the morning. The first softer, easier bowel movement most women have had since starting their medication.
- Week 1
The 6pm bloat starts backing off. Less pressure at night. Waistband still comfortable after dinner.
- Weeks 2–3
Going most mornings on your own, and it feels finished. Many women start cutting their MiraLAX in half.
- Weeks 4–6
Most women are off the laxatives. Still on their GLP-1, same dose, same goal weight. Same one sachet at dinner.
"Do I have to stop my medication?"
No. Keep taking your GLP-1 exactly as prescribed. KORE doesn't replace or change your medication. It works on what the medication does to your gut: the slowdown, the starving crew and the dinner that sits overnight. If you're on several prescriptions, check with your prescriber before adding any supplement.
Will it affect my weight loss? A sachet is a few grams of soluble fiber with no sugar. Nothing in it is designed to increase your appetite, and women keep taking their medication as usual alongside it.
What about nausea? It dissolves clear with no grit, and you start with half a sachet for the first 4 nights. Take it with dinner, sipped slowly, rather than on an empty stomach.
What if it doesn't work for me? Constipation on a GLP-1 usually comes down to the same things: a slowed gut, a starving crew and a dinner that never fully breaks down. That's the pattern this is built for. Not every case is that, and if it doesn't work for you, it's covered.

Your medicine cut their food. This puts it back.
The drug did exactly what it was supposed to do. It slowed everything down and turned down the hunger. Nobody told the bacteria in your gut they'd be working on a starvation budget, or that your dinner would sit half-digested until morning. MiraLAX can't fix that. It doesn't feed anyone. One sachet in a glass of water with dinner holds water inside the stool, feeds the crew and helps the meal break down, with your GLP-1 still on board. You keep the weight loss. You get your mornings back.
One sachet. With dinner. Keep your GLP-1.
