Quick answer (40–60 words)

If your sleep gets weird on GLP-1, the best first move is usually boring consistency: hydration (often electrolytes if you feel flat/crampy), a small protein anchor earlier in the day, and a simple wind-down routine. If you want a supplement trial, start with one option (often magnesium or a calming topical routine) for 2–3 weeks before adding anything else.

Why GLP-1 can mess with sleep (even when weight loss is “working”)

In my own GLP-1 weight loss journey, sleep disruption was rarely fixed by “more stuff”. It improved when I got the basics repeatable.

Common reasons sleep can wobble on GLP-1:

• Lower food volume → you can drift into low protein/low intake days, which can feel like “wired but tired”.
• Hydration drops (often without noticing) → headaches, cramps, restless legs, and general fatigue can creep in.
• Slower digestion → bloating/reflux/heaviness can make lying down uncomfortable.
• Routine changes → caffeine timing, later meals, anxiety around side effects, and general body change can all impact sleep.

The goal isn’t a “sleep mega-stack”. It’s one change at a time, tested long enough to know if it actually helps.

The 10-minute “start tonight” routine (what I’d do first)

1. Hydration check: if you’ve barely drunk today, start with small sips for 60–90 minutes. If you’re headachy/crampy/flat, consider electrolytes earlier in the day tomorrow (not a massive slug right before bed).
2. Stop the “late heavy meal” trap: on GLP-1, a big late meal can sit like a brick. Keep dinner lighter and earlier if you can.
3. Wind-down anchor: pick one tiny habit you’ll repeat (shower, book, stretch, breathing). Boring wins.
4. If you trial a product: choose one option for 2–3 weeks (magnesium or a calming topical routine are the cleanest tests).

Best picks (minimal, GLP-1-friendly)

These are the options I’d consider first. I link to the hub product page so you can read the notes calmly, then the official Lily & Loaf page second (affiliate).

1) Sleep Massage Oil (calm wind-down routine)

Why I’d try it: This is a “ritual” product. It helps because it makes you do the wind-down consistently.

2) Double Magnesium (simple nightly baseline)

Read more: https://alanspicer.com/best-health-supplements/products/double-magnesium.html
Why I’d try it: A straightforward magnesium option if tension/cramps/restless evenings are part of the picture. Start low and go slow.

3) Triple Magnesium (if you want a stronger “evening routine” feel)

Read more: https://alanspicer.com/best-health-supplements/products/triple-magnesium.html
Why I’d try it: If you’ve tried basic routine changes and still feel crampy/tight/restless, this can be a reasonable trial. (Again: one change at a time.)

4) Sleep Collection (gift set / “make it easy to stick to”)

Read more: https://alanspicer.com/best-health-supplements/products/sleep-collection.html
Why I’d consider it: If you’re the type who does better with an “all-in one” routine, sets can remove decision fatigue.

5) Electrolyte Drink (if cramps / “flat” fatigue are wrecking your nights)

Read more: https://alanspicer.com/best-health-supplements/products/electrolyte-drink.html
Why I’d consider it: This is often the hidden lever on GLP-1: appetite drops, drinking drops, and you feel rubbish. Use earlier in the day if it perks you up.

Decision fatigue / want an easy routine	Sleep Collection	Helps you stick to a routine by removing choices	2–3 weeks	https://alanspicer.com/best-health-supplements/products/sleep-collection.html
“Flat” fatigue + cramps + headaches	Electrolytes	Hydration consistency is a common missing piece on GLP-1	3–7 days	https://alanspicer.com/best-health-supplements/products/electrolyte-drink.html

Rule of thumb: pick one change. If you start magnesium, oils, electrolytes and a new “sleep tea” on the same day and sleep better… you’ll never know what actually helped.

What NOT to do (trust booster)

• Don’t stack lots of new products at once. It increases side effects and kills your ability to learn what works.
• Don’t fix fatigue with late caffeine. You borrow energy from tomorrow and make sleep worse.
• Don’t eat a big late meal “because you didn’t eat much today”. On GLP-1 it can sit heavy and disrupt sleep.
• Don’t ignore reflux/bloating. If lying down feels bad, fix digestion timing/meal size first.
• Don’t push through severe symptoms. Persistent vomiting, severe constipation, fainting, chest pain, or dehydration needs medical advice.

Timeline: what to expect (3 days / 2 weeks / 30 days)

In 3 days: If you were under-drinking, hydration consistency can reduce headaches/cramps and make nights calmer. Routine tweaks can also help quickly (earlier lighter dinner, less screen time).

By 2 weeks: A consistent wind-down habit starts to “train” your evenings. If magnesium is a fit for you, this is usually where you’ll notice whether it’s worth keeping.

By 30 days: You’ll know the winners. The goal is a routine that feels boring — because boring is sustainable.

Objections (and straight answers)

“Isn’t this expensive?”
It can be — which is why I’m big on one change at a time. Start with the lowest-cost lever (routine + hydration), then choose one product that matches your main problem.

“What if magnesium upsets my stomach?”
That can happen. Start low, take with food if needed, and stop if you get loose stools or feel worse. If you’re on medication, check interactions.

“What about interactions?”
Important. Supplements can interact with meds and conditions. If you take prescriptions (especially blood pressure meds, thyroid meds, blood thinners, diabetes meds), speak to a pharmacist/clinician before adding anything new.

“When should I stop?”
If something makes symptoms worse, stop immediately. If you see no meaningful benefit after a fair trial window, it’s probably not the right fit.

FAQs (snippet-first)

1) Can GLP-1 medications cause insomnia?

They can contribute indirectly: lower food intake, dehydration, slower digestion, reflux/bloating, and routine changes can all affect sleep.

2) What’s the simplest fix for poor sleep on GLP-1?

Start with hydration consistency, earlier lighter meals, and a repeatable wind-down routine. Then trial one product only if needed.

3) Should I take magnesium on Mounjaro/Wegovy?

Some people find it helpful for tension/cramps/restlessness. Start low, go slow, and check interactions if you take medication.

4) Why do I feel “wired but tired” on GLP-1?

It’s often low intake days, dehydration, disrupted sleep, or stress. Fix basics first before adding lots of supplements.

5) Do electrolytes help sleep?

They can help if cramps/headaches/flat fatigue are linked to low fluids. Use earlier in the day if they energise you.

6) What if I get reflux at night on GLP-1?

Try smaller earlier meals, avoid lying down right after eating, and consider whether bloating/heaviness is driving it.

7) How long should I trial a sleep supplement?

Usually 1–3 weeks of consistent use (unless you feel worse — then stop).

8) Can I stack magnesium and a sleep oil routine?

Yes, but don’t start both on the same day. Add one change at a time so you can tell what helped.

9) What’s the best time to take magnesium?

Commonly 30–60 minutes before bed, but follow the label and adjust based on how you feel.

10) Who should avoid magnesium or check first?

If you have kidney issues, take prescriptions, or have medical conditions, check with a clinician/pharmacist first.
