We Tested 5 Ways To Fix Constipation On Weight Loss Injections. Which One is Currently #1?

Monday, May 18, 2026 / By Julia Morris

Going to the bathroom used to be the most ordinary thing in the world.

Then you started your weight loss injection — and suddenly, you can't go at all.

If you've spent weeks bloated, uncomfortable, and backed up no matter what you try, you're not imagining it. It's one of the most common complaints from women on these medications, and in our recent survey, it came in as the #1 reason women considered stopping a medication that was actually working for their weight loss.

So we ran a 4-month test with 52 women on GLP-1 weight loss injections who were all struggling with ongoing constipation.

The goal: find the most effective solution for getting regular again — without stopping the medication.

We tested:

ViraRoot GLP-1 Support Formula
MiraLax
Metamucil
Dulcolax
Colace

These 52 women were split into 5 groups and used each solution consistently for 4 months.

We tracked results using weekly check-ins and self-reports on:

Return to regular bowel movements
Bloating and discomfort relief
Ease of use / daily comfort
Side effects

Title

#1 — ViraRoot GLP-1 Clinical Support Formula

The only solution built specifically for constipation caused by weight loss injections

What it is

A multi support formula with Magnesium Citrate, Ginger Root Extract, and a 19-Strain Probiotic Blend — designed specifically for the digestive slowdown caused by GLP-1 medications.

How it worked

This was the clear standout. Most women in this group reported noticeable improvement within the first 5–7 days. Unlike every other solution we tested, ViraRoot was formulated with GLP-1 side effects in mind — it works with the slowed digestive system rather than trying to fight it. Women said they felt lighter, less bloated, and were finally going regularly without cramping or urgency. Several said it was the first time since starting their medication that their gut felt normal again.

Price: $29.99 (currently 40% off, normally $49.99)

Data from weekly check-ins and self-reports:

Return to regular bowel movements: Very high
Bloating and discomfort relief: Very high
Daily comfort: Very high
Side effects: None reported

Pros

Magnesium Citrate gently draws water into the intestine — no cramping, no fighting the medication
Ginger Root Extract (5% Gingerols) is a clinically studied prokinetic that supports natural gut rhythm
19-Strain Probiotic at therapeutic dose restores the gut signals that GLP-1 medications suppress
The only solution in our test designed for a GLP-1 gut specifically

Cons

Only available online
Sells out often because of the high demand (especially during sale events)

#2 — MiraLax

Offers some relief, but results were inconsistent over time

What it is

An osmotic laxative that draws water into the colon to soften stool and encourage a bowel movement.

How it worked

MiraLax was the second most effective option in our test, and some women did find short-term relief — particularly in the first few weeks. The problem was consistency. Because it doesn't address the slowed gastric emptying that causes the backup in the first place, several testers found they needed to use more of it over time to get the same result. It also did nothing for bloating or general digestive discomfort.

Price: $20

Data from weekly check-ins and self-reports:

Return to regular bowel movements: Moderate
Bloating and discomfort relief: Low
Daily comfort: Moderate
Side effects: Mild (cramping, inconsistent urgency)

Pros

Widely available and affordable
Works for some women in the short term

Cons

Effectiveness decreased over time for most testers
Doesn't address the root cause of GLP-1-related constipation
No relief from bloating or digestive discomfort

Title

#3 — Metamucil

Well-intentioned, but often made things worse

What it is

A soluble fiber supplement that adds bulk to stool to stimulate bowel movements.

How it worked

Metamucil is one of the most commonly recommended solutions for constipation — and the most commonly recommended by doctors for women on GLP-1 medications. Unfortunately, it was the solution that backfired most often in our test. Fiber needs movement to work, and GLP-1 medications significantly slow that movement. Several testers reported feeling more bloated and more backed up after adding fiber — not less. To be fair, a few women did see mild improvement early on, but it wasn't sustained.

Price: $29.99

Data from weekly check-ins and self-reports:

Return to regular bowel movements: Low
Bloating and discomfort relief: Low
Daily comfort: Low
Side effects: Moderate (increased bloating, worsened discomfort)

Pros

Cheap and widely available
Can support general digestive health outside of GLP-1 use

Cons

Several testers reported it made bloating and constipation worse
Designed for a normal gut, not a GLP-1-slowed one
Frequently recommended but not suited to this specific problem

Title

#4 — Dulcolax

Occasional relief, but unpredictable and uncomfortable

What it is

A stimulant laxative that triggers muscle contractions in the intestines to force a bowel movement.

How it worked

Some women got relief with Dulcolax — but it came with strings attached. GLP-1 medications suppress intestinal contractions, and stimulant laxatives work by triggering those same contractions. That clash produced cramping and urgency for several testers, and for others produced nothing at all. Results were unpredictable. A few women used it as a one-off rescue option with some success, but none said they'd use it as an ongoing solution.

Price: $12.99

Data from weekly check-ins and self-reports:

Return to regular bowel movements: Low to moderate
Bloating and discomfort relief: Low
Daily comfort: Low
Side effects: Moderate to strong (cramping, urgency, unpredictable timing)

Pros

Fast-acting in some cases
Inexpensive and easy to find

Cons

Cramping and unpredictable urgency reported by most testers
Works against the GLP-1 mechanism rather than with it
Not suitable for regular use

Title

#5 — Colace

The most disappointing result of the test

What it is

A stool softener that moistens stool to make it easier to pass.

How it worked

Colace produced the least noticeable effect of any solution we tested. In theory, softer stool should be easier to pass. In practice, soft stool still doesn't go anywhere in a gut that isn't contracting. Most women in this group reported no meaningful change after two weeks of consistent use. A few said they saw a very minor improvement, but nothing they would describe as relief. Of all five solutions, this was the one most testers quietly stopped bothering with.

Price: $14.99

Data from weekly check-ins and self-reports:

Return to regular bowel movements: Very low
Bloating and discomfort relief: Very low
Daily comfort: Very low
Side effects: None reported

Pros

No side effects
Very affordable

Cons

Virtually no effect for most testers on GLP-1 medications
Does nothing to address the underlying motility issue
The least effective option in our 4-month test

Title

Final Word

Every woman in this test was dealing with the same problem — and every solution offered at least something. But the gap between first and second place was hard to ignore.

ViraRoot GLP-1 Clinical Support Formula was the only solution formulated for the way these medications actually affect your digestive system. It produced the most consistent relief, the most comfortable results, and zero side effects across 4 months of testing.

If you've already tried the usual fixes and they haven't worked, this is the one we'd recommend.

Finally something that explains WHY fiber makes it worse. My doctor kept telling me to eat more of it and I felt awful. This actually makes sense.

I used MiraLax for almost 2 months. Helped a little at first then just stopped working. Ordered ViraRoot, hoping this is finally the one.

Been on my injection for 3 months and the constipation has been the worst part by far. Dulcolax gave me cramps and nothing else. Glad I'm not the only one this happened to.

Just ordered ViraRoot. Will report back. The part about the ginger supporting gut movement rather than just forcing things along makes a lot of sense to me.

This is the first article I've found that actually explains the mechanism properly. Not just "drink more water and eat more fiber." Thank you.

I nearly quit my injections because of this. The bloating and not being able to go was worse than the weight. So relieved there's actually something designed for this specifically.

Colace did absolutely nothing for me. Zero. And I used it for three weeks thinking I was doing the right thing. Wasted time and money.

5–7 days for results sounds too good to be true honestly, but I've tried everything else so I'm ordering anyway. Will update.

Update from my earlier comment — been on ViraRoot for 3 weeks now. Going regularly for the first time since I started my injection. Genuinely shocked at how fast it worked.
