On a GLP-1? Your Gut Is Along for the Ride.
You did the hard part already. You talked to your doctor, you started the shots or the pills, and you’ve stuck with it. Some weeks are easy. Some aren’t.
And there’s the part nobody puts in the before-and-after photos. The bloating after a meal half the size you used to eat. The days things move too slowly, or not slowly enough. The quiet adjusting you do around your own stomach.
You’re not imagining it. Nausea, diarrhea, constipation and stomach pain are among the most common side effects listed in the prescribing information for semaglutide. If you’ve felt it, you’re in good company.
Your gut didn’t sign up for this, but it’s adapting too
Your digestive tract is home to trillions of microbes, your gut microbiome. They feed on what you eat. On a GLP-1, you eat less, and food moves through you differently. Your microbes notice.
Researchers are only starting to study what GLP-1 medications do to the microbiome. The early findings are small and mixed. What isn’t in question is that your gut is working with a new routine.
One small, steady thing
The GLP One is a daily probiotic made for people on a GLP-1. It’s one capsule a day with lunch or dinner: two strains, Bifidobacterium longum and Bacillus coagulans, on a gentle, non-gelling fiber called partially hydrolyzed guar gum. 24 billion CFU.
It supports healthy gut motility and everyday digestive comfort.† That’s it. It doesn’t change your medication, and it isn’t trying to.
To be straight with you: no study has tested these ingredients in people taking GLP-1s. We picked them for what they do in the gut, and we’d rather tell you that than dress it up.
A few honest notes
- Take it with a meal, and not within 30 minutes after an oral semaglutide pill.
- If you have gastroparesis, a past bowel obstruction or trouble swallowing, talk to your clinician first.
- It isn’t for kids.
You already chose to take your health into your own hands. This is just one easy, daily habit to go with it.
