Caffeine pouches: myths and facts
There is a lot of confusion about caffeine pouches, partly because they look exactly like nicotine pouches and partly because the category is new enough that a lot of what gets repeated online has never been checked. Here is what is true, what is not, and where the honest answer is "nobody knows yet."
PAX is caffeine. There is no nicotine in it and there never will be.
Do caffeine pouches contain nicotine?
No. A caffeine pouch contains caffeine. PAX contains 100mg of caffeine per pouch, no nicotine and no tobacco.
The confusion is the format, not the contents. Caffeine pouches borrowed the shape, the tin and the under-the-lip habit from nicotine pouches, so they sit next to each other on a shelf and look identical. That is where the resemblance stops.
Two things worth knowing when you compare brands. At least one brand on the New Zealand shelf sells both a nicotine line and a caffeine line under the same name in different markets, so check which one you are holding. And PAX has no nicotine or vaping business of any kind. Caffeine is all we do.
Do caffeine pouches contain fibreglass?
No. There is no glass in a PAX pouch.
The myth is about the little bag, so here is what the bag is made of: 80 percent viscose and 20 percent polyester. Viscose is a fibre made from wood pulp. Polyester is the same family of material as the fabric in your clothes. Neither one is glass.
Inside the bag is a white powder. The bulk of it is microcrystalline cellulose, which is plant fibre. The European Food Safety Authority has assessed it and found no safety concern at the levels it is used at. It is not absorbed by the body and passes through intact.
Where the myth comes from is that powder. It is white and crystalline, and if a pouch splits, it looks like something it is not. Some people also feel a tingle and put it down to tiny cuts. That tingle is real, but it is not glass, and there is a proper answer to it further down this page.
Do caffeine pouches work faster than coffee?
No, and we would rather say so than sell you something that is not true.
It is the most repeated claim in this category and it does not hold up. Caffeine in a drink is already absorbed almost completely, so there is no digestive hold-up for a pouch to skip past. In plain water it peaks in the blood at around 30 minutes. Coffee is a little slower again.
In 2025 researchers tested a sublingual caffeine spray, which puts the dose straight onto the lining of the mouth in one go, head to head against coffee and an energy drink. It was not faster than either, at any point in the measurement. A pouch releases its caffeine more slowly than a spray does, not faster.
Nobody has ever measured a PAX pouch specifically, so anyone who quotes you an exact number of minutes for any brand is guessing.
What a pouch actually changes is that you do not need a drink. No cup, no queue, no can to carry, nothing to spill in a work ute. That is the real difference, and it is enough.
How long do you keep a pouch in?
Place it between your lip and gum and leave it there. Do not chew it and do not swallow it. One pouch per serving.
The caffeine is released for absorption in your mouth while the pouch sits there. There is no timer on it. We keep ours in for 20 to 30 minutes and take them out when the flavour goes. If you are still enjoying it, leave it in longer.
Move it around rather than parking every pouch in the same spot, and if the place where it sits starts to feel sore or look different, take it out.
How long does the caffeine last?
Hours, not minutes, and much longer than the pouch is in your mouth. Those are two different questions and they get mixed up constantly.
Caffeine's half life sits somewhere between roughly three and ten hours. That is a wide range because people clear caffeine at very different rates.
That matters most in the evening. Research has found that 400mg of caffeine taken six hours before bed still disrupts sleep. If you are sensitive, work it backwards from when you want to be asleep.
Is 100mg really "about the same as a coffee"?
Roughly, and it depends entirely on which coffee you mean.
| caffeine | |
|---|---|
| One PAX pouch | 100mg |
| Instant coffee, one cup (FSANZ figure) | about 80mg |
| Brewed or espresso based cafe coffee | about 95mg to 200mg |
On the FSANZ figure, one PAX pouch is a bit more than one instant coffee, not less. Against a cafe coffee it is about one or less.
We have described a pouch as "about the same as a coffee" without saying which coffee, and that is not precise enough. If you are counting your daily caffeine, count a PAX pouch as 100mg, because that is exactly what it is. That is the only number that does not move.
How many can you have in a day?
No more than four PAX pouches, and only if you are not getting caffeine from anywhere else.
Four pouches is 400mg. FSANZ describes 400mg a day as a safe habitual intake for healthy adults. The catch is the word "total". Four pouches plus your morning flat white puts you over, and that is the mistake that is easy to make with a product you can keep in your pocket.
One pouch per serving. PAX contains caffeine, and too much caffeine can cause an accelerated heart rate, nervousness, irritability and trouble sleeping.
PAX is for adults 18 and over. It is not for you if you are pregnant or breastfeeding, or if you are sensitive to caffeine. If a strong coffee already makes you wired, this is not for you. If you have any medical condition, talk to your doctor before using it.
Are caffeine pouches habit-forming?
Caffeine can cause dependence, and we are not going to pretend otherwise.
Research has found that people who stop after regular daily use as low as 100mg get symptoms. That is one PAX pouch. Headache is the best documented and turns up in about half of cases, alongside tiredness.
This is true of coffee, tea, energy drinks and cola in exactly the same way. It is not something a pouch does that a flat white does not. But if you are starting from no caffeine at all, you are starting a caffeine habit, and it is fair that you know that going in.
Do caffeine pouches damage your gums?
Nobody knows, because nobody has studied it. That is the honest answer and anyone who tells you otherwise is guessing.
We looked properly. There is no published research anywhere on what caffeine pouches do to oral tissue. Only a handful of papers on caffeine pouches exist at all, one of them has been retracted, and not one of them examined anyone's mouth.
What we can tell you is our own experience. We used these daily for months before we launched in New Zealand, and we still do. Nobody on our team has had a problem with their gums, and no customer has reported one. That is worth something. It is also not the same thing as a study, and we are not going to dress it up as one.
What has been studied is the pouch format generally, mostly nicotine pouches and Swedish snus. Those products contain nicotine, and snus contains tobacco compounds, neither of which is in a caffeine pouch, so the findings cannot be read straight across. With that limit clearly stated, two things in that research are worth taking seriously.
The first is that changes to the lining of the mouth at the spot where the pouch sits are reported consistently. The second is that researchers describe the cause as both chemical and mechanical, and the mechanical half, which is simply pressure in the same place for a long time, does not require nicotine to be present.
Practical advice we would give a friend: move it around. Do not park every pouch in the same spot. And if the tissue there looks or feels different, stop and see a dentist.
You may also see a statistic quoted online about a university study finding gum recession in a majority of pouch users. We went looking for it. It has no journal and no author, we could not find it in the medical literature, and it circulates on pages selling pouches. We are not going to repeat it.
Can a pouch make your gums burn or sting?
A mild tingle when you first put one in is normal. That is the cooling agent in the flavour, and it passes.
A proper burn or sting that does not settle is a different thing. A small number of people react to flavourings, in a pouch or in anything else, and every PAX tin names its flavour ingredients. If it happens, take the pouch out. If it keeps happening, stop using them and talk to a dentist or your doctor. It is not something to push through.
Do the added vitamins in some brands do anything?
It depends entirely on the amount, and the amount is often much smaller than the front of the tin suggests.
Some caffeine pouch brands add vitamins, minerals or amino acids. When you are comparing, the number to look for is not whether an ingredient is present but how much of it there is, and whether that figure is given per pouch or per tin. Those are very different things when a tin holds twenty pouches.
Taurine is a good example. At least one brand states 100mg per pouch. Published research on taurine has generally used 1,000mg to 2,000mg, and whether it does anything at 100mg has not been tested. So the honest answer is that nobody knows, not that it does nothing.
PAX adds no vitamins, no minerals and no amino acids. The caffeine dose is a fixed 100mg a pouch.
