Quick answer (snippet-ready)
Sulphur (“rotten egg”) burps on GLP-1 meds are usually caused by slow digestion + food sitting longer, often alongside reflux, bloating or constipation. Start with smaller meals, less fat, slower eating, and hydration. If you want a supplement trial, keep it simple: many people do best testing digestive enzymes with meals first, then a soothing option like slippery elm. Charcoal can help gas for some people, but it can also interfere with medications—so timing matters.

Why sulphur burps happen on GLP-1 (even when the meds are “working”)
GLP-1 medications can slow gastric emptying. That’s part of how they help appetite control—but it also means food can sit in the stomach longer. When digestion is slower, some people notice:
- More burping (sometimes with a sulphur smell/taste)
- Bloating / heaviness after meals
- Reflux/heartburn (especially after fatty meals)
- Constipation (which can make everything feel worse upstream)
In my own GLP-1 weight loss journey, the biggest “fix” was rarely a giant supplement stack. It was usually boring consistency: meal size, meal timing, hydration, and then one targeted trial at a time.
The 10-minute “start here” plan (do this before you buy anything)
- Go smaller for 48 hours: reduce portion size and slow down your eating. If you’re forcing “normal-sized” meals, your stomach may disagree.
- Cut fat for a few days: high-fat meals are a common trigger for reflux + slow digestion on GLP-1.
- Stop fizzy drinks for now: carbonation adds gas and makes burping worse.
- Hydration consistency: aim for steady fluids across the day (not a huge chug at night).
- Check constipation: if you’re not moving things through regularly, burps/bloating often persist.

Best picks (minimal trials): what I’d try first
Rule of thumb: choose ONE to trial first. If you start enzymes + charcoal + fibre on the same day and feel better… you’ll never know what actually helped.
1) Enzymes+ (first trial if meals sit heavy / bloating / burps after eating)
Hub page: https://alanspicer.com/best-health-supplements/products/enzymes-plus.html
Why I’d try it: If the burps kick off after meals and you feel “food sitting there”, enzymes are a clean, symptom-matched trial.
2) Slippery Elm (if you feel sore/irritated, refluxy, or “raw” in the upper gut)
Hub page: https://alanspicer.com/best-health-supplements/products/slippery-elm.html
Why I’d try it: It’s a “soothing” option some people use when digestion feels irritated. If your burps come with reflux or discomfort, this is a gentler-style trial.

3) Activated Charcoal (gas support, but be careful with timing)
Hub page: https://alanspicer.com/best-health-supplements/products/activated-charcoal.html
Why I’d consider it: Some people use charcoal for gas/bloating. But: charcoal can bind things in the gut, which is why timing away from medications and other supplements matters.

4) Aloe Vera Juice (gentle digestive comfort + hydration routine)
Hub page: https://alanspicer.com/best-health-supplements/products/aloe-vera-juice.html
Why I’d consider it: If you want something simple to build into a daily routine (especially when appetite is low), aloe is often used as a gentle digestive support.

5) Super Fibre (only if constipation is part of the story)
Hub page: https://alanspicer.com/best-health-supplements/products/super-fibre-450g.html
Why I’d consider it: If you’re backed up, burps and bloating can hang around. Fibre can help—but introduce it slowly and keep fluids up.

Comparison table: pick the right option (don’t stack everything)
| If your main issue is… | Start with | Why it’s a sensible first step | Give it a fair test | Hub page |
|---|---|---|---|---|
| Burps + heaviness after meals | Enzymes+ | Meal-linked support you can judge clearly | 7–14 days | https://alanspicer.com/best-health-supplements/products/enzymes-plus.html |
| Sore/irritated upper gut, refluxy feeling | Slippery Elm | Gentler “soothing” routine for digestive comfort | 2–3 weeks | https://alanspicer.com/best-health-supplements/products/slippery-elm.html |
| Gas/bloating (and you want a short, targeted trial) | Activated Charcoal | Some people find it helps gas; timing away from meds matters | 3–7 days | https://alanspicer.com/best-health-supplements/products/activated-charcoal.html |
| Digestive discomfort + you want a daily hydration-friendly routine | Aloe Vera Juice | Easy routine; can be gentler than pills for some people | 2–4 weeks | https://alanspicer.com/best-health-supplements/products/aloe-vera-juice.html |
| Burps + bloating + constipation together | Super Fibre (slow start) | If you’re backed up, upstream symptoms often improve | 2–4 weeks | https://alanspicer.com/best-health-supplements/products/super-fibre-450g.html |
Rule of thumb: pick one option, run it consistently, then reassess. Most people get better results from boring consistency than from stacking five things at once.
What NOT to do (trust booster)
- Don’t “detox” or cleanse aggressively. If digestion is slow on GLP-1, harsh approaches often make things worse.
- Don’t force huge meals. Smaller, simpler meals usually win while your body adapts.
- Don’t combine loads of new supplements at once. You won’t know what helped (or what caused side effects).
- Don’t ignore constipation. If you’re not going regularly, burps/bloating/reflux often stick around.
- Don’t take charcoal anywhere near meds. If you use it, keep it well separated from prescriptions and other supplements.
Timeline: what to expect (24 hours / 7 days / 30 days)
In 24 hours: Switching to smaller meals, cutting fat, avoiding fizzy drinks, and slowing down eating can reduce burps quickly for some people.
In 7 days: If enzymes are the right match (meal-linked heaviness), you’ll often notice clearer changes within a week. If constipation is a driver, you may need consistent fluids + fibre support to see improvements.
In 30 days: You’ll know what’s worth keeping. The goal is a routine that feels boring—because boring is repeatable.
Objections + safety (straight answers)
“Is this normal on Mounjaro/Wegovy?”
It’s common for digestion to feel slower on GLP-1, and burping can show up alongside reflux, bloating, nausea or constipation. If symptoms are severe, persistent, or worsening, speak to a clinician.
“What if I’m nauseous too?”
Keep the plan simple (small meals, bland foods, hydration). If nausea is leading the story, start with this hub guide: https://alanspicer.com/best-health-supplements/nausea-on-glp1.html
“Won’t charcoal interfere with medication?”
It can. That’s why timing matters. If you take prescription meds, this is a “check first” product—ask a pharmacist how to separate it safely, or skip it.
“When should I stop a supplement trial?”
If symptoms worsen, you feel unwell, or you get new side effects—stop and reassess. No supplement is worth feeling worse for.

FAQs (snippet-first)
1) Why do GLP-1 meds cause sulphur burps?
Usually because digestion slows and food sits longer, which can increase burping (sometimes with a sulphur taste/smell), especially after heavier meals.
2) Are sulphur burps a sign something is wrong?
They’re common with slow digestion, but if you have severe pain, repeated vomiting, black/tarry stools, blood, or worsening symptoms, get medical advice promptly.
3) What foods make sulphur burps worse on GLP-1?
Often high-fat meals, very large portions, fizzy drinks, and sometimes eggs/very rich proteins. The simplest test is smaller, lower-fat meals for 48 hours.
4) What’s the fastest fix for rotten egg burps?
Smaller meals, less fat, no fizzy drinks, slower eating, and hydration. If you want a supplement trial, enzymes with meals are a common first test.
5) Do digestive enzymes help sulphur burps?
They can help if burps are meal-linked and you feel heaviness/bloating after eating. Trial for 7–14 days and reassess.
6) Can activated charcoal help with gas and burps?
Some people find it helps gas, but it can interfere with medications/supplements—so timing and safety checks matter.
7) How far away from meds should charcoal be taken?
Ask a pharmacist for personalised advice. If you’re on prescription meds, treat charcoal as a “check first” product.
8) Does constipation make burps worse on GLP-1?
It can. If things aren’t moving, bloating and reflux/burping often worsen. Fluids, gentle fibre, and consistency matter.
9) Is slippery elm safe on GLP-1?
It’s often used as a soothing option, but suitability depends on your health and meds. Check labels and introduce one change at a time.
10) Can aloe vera juice help GLP-1 digestion?
Some people use it as a gentle digestive comfort routine. Start small and stop if it worsens symptoms.
11) Should I stop my GLP-1 dose if I get sulphur burps?
Don’t change medication without medical advice. Try the food-first plan and speak to your prescriber if symptoms are persistent or severe.
12) When should I worry about dehydration?
If you’re dizzy, very dry-mouthed, peeing very little, or can’t keep fluids down—especially with vomiting/diarrhoea—seek medical advice.
13) What if sulphur burps come with reflux?
Reduce fat, go smaller, avoid late-night meals, and check this related guide: https://alanspicer.com/reflux-heartburn-on-glp1-what-actually-helps-uk/
14) What’s the simplest supplement routine for this problem?
Pick one: enzymes with meals, or slippery elm if you feel irritated/refluxy. Only add fibre if constipation is clearly part of it.
