Not medical advice. Always check labels and speak to your GP/pharmacist/clinician if you’re pregnant/breastfeeding, have a medical condition, or take medication (especially blood pressure meds, diuretics, thyroid meds, anticoagulants/blood thinners, diabetes meds). If anything makes symptoms worse, stop and reassess.
If you’re feeling sick on GLP-1, you’re not “failing” — it’s one of the most common friction points. In my own GLP-1 weight loss journey, the biggest wins weren’t “fancy stacks”… it was getting the boring basics consistent (hydration + smaller meals + slower eating) and only adding one targeted support at a time.

Quick answer (60 seconds)
If GLP-1 nausea is kicking your teeth in, start with hydration consistency (small sips all day) and smaller, simpler meals (protein-first, lower fat, slower eating). Give that 3–7 days. If you still feel rough, try one gentle option (peppermint/chamomile tea or slippery elm) and test it for 1–2 weeks. Don’t stack five things at once.

Why GLP-1 nausea happens (even when it’s “working”)
GLP-1 meds do a few things that can make nausea more likely:
- They slow digestion (food sits longer → “heavy” feeling).
- They reduce appetite (you eat less, but also often drink less).
- They can change food tolerance (high-fat meals can suddenly feel like a mistake).
- Dose changes can temporarily amplify side effects.
Most of the time, the goal is not “find a magic pill”. It’s: reduce triggers, keep fluids steady, and add one targeted support only if needed.
Decision flow: what to do first (no overthinking)
If you feel nauseous mainly in the morning
- Try small sips first (don’t chug).
- Have a tiny protein-led bite (even half a yoghurt / a few bites) before you “test” coffee.
- Aim for plain, lower-fat early meals.
If nausea hits after meals
- Cut meal size by 20–30% for a week and eat slower.
- Reduce fat bombs (fried foods, creamy sauces) while symptoms are high.
- Consider peppermint or chamomile tea after meals.
If nausea comes with “washed out” fatigue / headaches
- Assume hydration drift until proven otherwise.
- Use electrolytes once per day and track how you feel for 3–7 days.
If nausea is paired with constipation / bloating
- Work the gut plan first (constipation makes everything feel worse).

- If meals feel “stuck”, enzymes can be a targeted trial (one change at a time).
Best picks (minimal, calm) — link to hub first, then buy
These are gentle options I’d consider one at a time. I always link to my hub product page first (notes + context), then the Lily & Loaf product page second.
1) Electrolyte Drink (hydration foundation)
Read more: https://alanspicer.com/best-health-supplements/products/electrolyte-drink.html
Why I’d try it: If nausea is worse when you’re tired, headachy, or “flat”, hydration drift is often part of the puzzle.

2) Water Bottle (behaviour beats willpower)
Read more: https://alanspicer.com/best-health-supplements/products/water-bottle.html
Why I’d try it: People underestimate how often nausea improves when you simply stop under-drinking. A bottle makes consistency easier.

3) Peppermint Herbal Tea (after-meal calm option)
Read more: https://alanspicer.com/best-health-supplements/products/peppermint-herbal-tea.html
Why I’d try it: A gentle, “sip slowly” option that can feel soothing after meals. Note: if peppermint worsens reflux for you, skip it.

4) Chamomile Blossoms Herbal Tea (evening settle-down)
Read more: https://alanspicer.com/best-health-supplements/products/chamomile-blossoms-herbal-tea.html
Why I’d try it: Useful when nausea is wrapped up with stress, tension, or “I can’t settle”.

5) Slippery Elm (throat/upper-stomach comfort style option)
Read more: https://alanspicer.com/best-health-supplements/products/slippery-elm.html
Why I’d consider it: If nausea feels like “upper stomach irritation” or your throat feels rough, this can be a gentle trial.
Important: Slippery elm may affect absorption of some medications/supplements — keep a 2-hour buffer either side and check with a pharmacist if unsure.

6) Enzymes + (only if meals sit heavy / bloating triggers nausea)
Read more: https://alanspicer.com/best-health-supplements/products/enzymes-plus.html
Why I’d consider it: If nausea is tightly linked to meals feeling “stuck” or heavy, enzymes can be a clean, targeted trial.
Tip: don’t start this on the same day as electrolytes — you won’t know what helped.

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 |
|---|---|---|---|---|
| “Washed out” nausea + headaches/dizziness | Electrolytes | Hydration drift is common on GLP-1; this is a fast variable to test | 3–7 days | https://alanspicer.com/best-health-supplements/products/electrolyte-drink.html |
| Nausea because you’re not drinking enough | Water bottle | Consistency beats willpower; sipping all day is easier than “catch-up” | 3–7 days | https://alanspicer.com/best-health-supplements/products/water-bottle.html |
| After-meal nausea (no reflux) | Peppermint tea | Gentle “sip slowly” option that’s easy to trial | 7–14 days | https://alanspicer.com/best-health-supplements/products/peppermint-herbal-tea.html |
| Evening nausea + tension / can’t settle | Chamomile tea | Pairs well with an evening routine; low effort, low drama | 7–14 days | https://alanspicer.com/best-health-supplements/products/chamomile-blossoms-herbal-tea.html |
| Upper stomach irritation / throat discomfort style nausea | Slippery elm | Gentle trial — but keep a buffer from medications | 7–14 days | https://alanspicer.com/best-health-supplements/products/slippery-elm.html |
| Heavy meals trigger nausea + bloating | Enzymes + | A targeted meal-based test (don’t stack with other new changes) | 1–2 weeks | https://alanspicer.com/best-health-supplements/products/enzymes-plus.html |
Rule of thumb: start with one change. If you add electrolytes + tea + enzymes + slippery elm in the same week and feel better… you’ll never know what actually helped.
What NOT to do (trust booster)
- Don’t chug fluids to “catch up”. Small sips usually land better.
- Don’t eat a massive meal because you “should”. Smaller, simpler meals are your friend on rough days.
- Don’t stack multiple new supplements at once. You’ll create mystery side effects.
- Don’t ignore constipation. If the gut slows down, nausea often gets worse.
- Don’t push through severe symptoms. Persistent vomiting, severe pain, fainting, or inability to keep fluids down = speak to a clinician.
Timeline: what to expect (3 days / 2 weeks / 30 days)
First 3 days: If hydration drift is a factor, small sips + electrolytes can change how you feel surprisingly quickly.
By 2 weeks: If you’ve reduced meal size, eaten slower, and kept fluids steady, nausea usually becomes less “random”. You can then test one gentle option (tea or slippery elm) and judge properly.
By 30 days: You’ll know your 1–2 “keepers”. The goal is a routine that feels boring — because boring is repeatable.
Objections + interactions (straight answers)
“Isn’t this expensive?”
It can be — which is why I’d start with the cheapest, highest-leverage change first: hydration consistency. If you do buy anything, buy one product matched to your main symptom, not six things out of panic.
“What if supplements make nausea worse?”
That’s why I prefer low-drama trials (tea, hydration tools, one targeted product at a time). If anything makes symptoms worse, stop. If nausea is severe or persistent, speak to a clinician.
“What about interactions?”
- Slippery elm: keep a 2-hour buffer from medications/supplements and check with a pharmacist if unsure.
- Electrolytes: if you have kidney/heart conditions, blood pressure issues, or fluid restrictions, check suitability first.
- Herbal teas: generally gentle, but if you have reflux, peppermint may not be your friend.
“When should I stop and get help?”
If you can’t keep fluids down, you’re getting dizzy/faint, you have severe abdominal pain, or vomiting is persistent — stop experimenting and speak to a clinician. Dehydration + GLP-1 is not a fun combo.

FAQs (snippet-first)
1) Why do GLP-1 medications cause nausea?
They slow digestion and change appetite signals, which can make meals feel heavier and nausea more likely — especially after dose changes or high-fat meals.
2) What is the best first step for GLP-1 nausea?
Hydration consistency (small sips all day) plus smaller, simpler meals. Give that 3–7 days before adding anything else.
3) Does dehydration make nausea worse on GLP-1?
Yes — many people drink less because appetite drops, and dehydration can amplify nausea, headaches, and fatigue.
4) What foods help when you feel sick on GLP-1?
Smaller portions, lower-fat meals, and protein-first choices that you tolerate. Bland and simple often wins on rough days.
5) What should I avoid eating when nausea is bad?
Large meals and high-fat “heavy” foods are common triggers. Reduce portion size and eat slower.
6) Can peppermint tea help nausea on GLP-1?
It can feel soothing for some people, especially after meals — but if you have reflux, peppermint may worsen symptoms.
7) Can chamomile tea help nausea?
It’s a gentle option that can pair well with an evening routine, especially if nausea is mixed with stress or tension.
8) What is slippery elm and when should I use it?
It’s often used as a gentle comfort option for upper stomach/throat irritation feelings. Keep it away from medications (2-hour buffer) and check with a pharmacist if unsure.
9) What if nausea happens after meals and you feel bloated?
Reduce meal size, slow down, and consider a targeted trial like enzymes if meals sit heavy — leaving time to judge if it helps.
10) Should I take lots of supplements at once to stop nausea?
No. Add one change at a time so you can spot what works and avoid mystery side effects.
11) How long should I trial a change before deciding it works?
Hydration changes can show impact in days. Most other options need 1–2 weeks of consistency to judge properly.
12) When should I speak to a clinician about nausea on GLP-1?
If you can’t keep fluids down, you’re faint/dizzy, you have severe abdominal pain, or vomiting is persistent — get medical advice.
13) Does nausea usually improve over time on GLP-1?
Often it does as your body adapts, especially if you reduce triggers and stay consistent with hydration and meal size.
