The days it steals
Curled up on the kitchen floor, off work, out of class. Around two days a month, gone. That is not a bad day: that is weeks of your year, every year.

Sound familiar?
You have been planning your life around your period for years.
The ibuprofen that barely touches it. The hot water bottle that needs the kettle every hour. The plans you cancel with an excuse that is not the real one. None of it is dramatic. It is just your life, two days a month, every month.
The painkiller ceiling
You take the pills. Then more than you should, and you start worrying what they are doing to your stomach and your liver. Some months they do not even touch the sides.
The hot water bottle trap
Heat is the one thing that reliably helps. But it tethers you to the sofa, cools within the hour, and it is one split seam away from a serious burn. Women end up in A&E over hot water bottles. That is not a relief plan.
There is finally a way to take the heat with you.
Meet Nutelix
The end of choosing between relief and your day.
Nutelix is a slim, cordless wrap that sits flat on your lower abdomen, under your clothes, and works three ways at once. Steady, controlled warmth relaxes the muscle. Gentle TENS pulses quiet the cramp signal. A soft massage mode keeps everything moving. You press one button and carry on with your morning.
- Controlled, even heat with no scald risk
- TENS relief trusted in physiotherapy for decades
- Massage mode for the deep, dragging ache
- And your day carries on: work, commute, sleep
How Nutelix works
1. The cramp fires.
Your uterus floods nearby nerves with pain signals. That wave is what folds you in half.
2. You place the wrap.
The butterfly pad sits low on your abdomen and moulds flat. Ten seconds, clothes back down.
3. The gate closes.
Gentle pulses give those nerves something calmer to carry, while steady warmth relaxes the muscle itself.
4. You carry on.
Coat on, kettle off. Not a miracle: the edge comes off, and the day goes back to being yours.
Three kinds of relief. Run one, or all three.
Heat
Steady, temperature-limited warmth across the whole pad.
Feels like: a hot water bottle that never cools and never scalds.
Pulse
Gentle TENS pulses that quiet the cramp signal on its way to your brain.
Feels like: a soft, rhythmic tingling you control completely.
Massage
A low vibration that keeps blood moving through the deep, dragging ache.
Feels like: fingertips pressing exactly where you would press.
Where it goes (30 seconds, once)
- Low on the abdomen, pad wings pointing at your hip bones
- On clean, dry, unbroken skin: it grips best there
- For back cramps, the same wrap moves to your lower back
Why pulses? Your nerves are a gate. A cramp floods that gate with pain signals. TENS gives the same nerves something gentler to carry instead, so less of the cramp gets through, while heat relaxes the muscle underneath. It is the same drug-free method physiotherapists have used for decades, folded into something you can wear.
The part that matters
Heat that leaves the house with you.
If heat is the only thing that ever truly helped, you are not imagining it: warmth relaxes the cramping muscle itself. The problem was never the heat. It was the delivery: boiling water, a fraying rubber seam, an hour of warmth and then a walk to the kettle. Nutelix holds a steady, controlled temperature against exactly the right spot for as long as you need it, with no water and no burn risk, and it walks out the door with you.
- Temperature-limited for safe skin contact
- Even warmth across the full butterfly pad
Invisible under clothes
Nobody knows it is there. You barely remember it is.
Slim enough for a waistband, silent enough for a library, cordless enough for a commute.
Be honest about the alternatives
You have tried everything except this combination.
Swipe to compare
TENS-only wearables are a real step up from nothing. But owners keep saying the same thing: without heat, on the worst days, it is not enough.
Why we built this
The conversations that started Nutelix.
My hot water bottle tore and the boiling water spilled onto my lower abdomen, giving me a second-degree burn.
I take so much Tylenol I worry about my liver.
It doesn't have a heat option, so I coupled it with an electric hot water bottle at night.
These are not reviews of Nutelix. They are the reason it exists: real women describing the gap every existing option leaves. We built the wrap we kept reading about: heat, pulses and massage in one, with pads you never have to re-buy.

Read this before you buy
Nutelix is not for everyone. Here is the honest version.
A great fit if
- Your cramps or pelvic and lower-back pain keep costing you work, class or sleep
- Heat clearly helps you, and you are sick of being tethered to a kettle
- You want a drug-free option to use alongside whatever your doctor advises
- You need relief that works at a desk, on a train, in public
Think twice if
- You have a pacemaker or any implanted electronic device (TENS is not for you)
- You are pregnant: talk to your doctor first
- The skin where you would wear it is broken or irritated
- Your pain is sudden, severe or new: that is a doctor conversation, not a gadget purchase
Nutelix is a drug-free relief device, not a treatment or cure for endometriosis, PCOS or any condition. It is designed to take the edge off so you can function, and for many women that is exactly the point. If your pain is getting worse or does not fit your usual pattern, please see your GP.
The fairest test we could design
Wear it for a full cycle. Then decide.
Thirty days is at least one period from now, and that is the whole point. Use Nutelix through a real cycle: the desk days, the commute, the 2am ache. If it does not genuinely take the edge off, email us within 30 days and we will refund every penny. No forms that fight you, no questions that are really objections.

Before you buy
Questions, answered honestly.
What does it actually feel like?
The heat feels like a hot water bottle that never cools and never scalds: steady warmth exactly where the cramp sits. The TENS pulses feel like a gentle, rhythmic tingling; you control the strength, and most women settle on a level they stop noticing within a minute. The massage mode is a soft vibration underneath it all. Nothing about it hurts, and you can run one mode or all three.
Will it really replace my hot water bottle?
That is the exact test we designed it for. The wrap holds a steady, temperature-limited warmth against your lower abdomen for as long as you wear it, with no boiling water, no cooling off after forty minutes and no being stuck on the sofa. If your bottle still wins after a full cycle, the 30-day trial exists for precisely that verdict.
Is it just an expensive TENS machine?
A fair question, because a bare TENS unit is cheaper. But TENS-only owners keep saying the same thing: on the worst days, pulses without heat are not enough. Nutelix is a TENS machine, a wearable heat pad and a massager in one slim wrap, with reusable pads, so you are not buying two devices or feeding either of them refills.
Do I have to keep buying replacement pads?
No, and this matters to us. The butterfly gel pads that come in the box are reusable: rinse, air-dry, re-stick. Replacement-pad costs are the single biggest complaint about other devices in this category, so we made spare pads cheap and optional, never a subscription.
Can I wear it at work or school without anyone knowing?
Yes. It is slim, silent and cordless, and it sits flat under a waistband. Wear it under jeans, a dress or a uniform; the most visible thing about it is that you look less pale by lunchtime.
I have endometriosis, adenomyosis or PCOS. Will it help me?
Honestly: it does not treat any condition, and we will never tell you otherwise. What it can do is what heat, TENS and massage do: take the edge off the pain so you can function, alongside whatever care you and your doctor have agreed. Many women with these conditions rely on exactly this combination for day-to-day relief. The trial covers you if your body disagrees.
Is it safe? Who should not use it?
The heat is temperature-limited and the TENS intensity is fully in your control. Do not use it with a pacemaker or any implanted electronic device, over broken or irritated skin, or in pregnancy without asking your doctor. If you have a heart condition, check first. And if your pain is sudden, severe or new, see your GP: that is more important than any purchase.
How quickly will I feel something?
The warmth spreads within moments of switching on, and the TENS pulses start working as soon as they reach a level you can feel. What that adds up to varies by body and by day; the honest promise is takes the edge off so you can carry on, not pain deleted in five minutes.
What is shipping like?
Free tracked UK shipping on every order. You get a tracking link the moment it leaves.
What is the return process, actually?
Email us within 30 days of delivery and say it was not for you. That sentence is the whole process: full refund, and the UK statutory 14-day right to cancel sits on top of it. We publish the 4-star reviews and honour the refunds; the brand only works if you can trust both.
Finally.
You have managed this on your own long enough.
Heat, TENS and massage in one wrap you can wear anywhere, with a full cycle to test it and every penny back if it fails you. The next bad day does not have to run the whole day.
