Zyn vs BRST: Pouch vs 2mg Nicotine Tablet
Zyn vs BRST compares a nicotine pouch you park on the gum with a 2mg tablet that melts under the tongue. Why can milligrams are not the whole story. 21+.
Key Takeaways
Lunell 2020 is Zyn’s own blood study: 3mg 7.7 ng/mL at 61 min, 6mg 14.7 at 66, 8mg 18.5 at 59.
Changing the milligrams on the can changed the peak height. It did not make the pouch fast.
BRST 2mg peaked at 14 minutes in Rose 2022 versus a lozenge. Pouch numbers come from Lunell. Tablet numbers come from Rose.
Zyn is a pouch. BRST is a melt. Different place in the mouth, different clock.
2mg peppermint melt. No pouch, no spit.
The future of nicotine is here.

Zyn did not become the default nicotine pouch by being mysterious. You buy a can, pack a small white sachet between your upper lip and gum, and leave it there. Nicotine leaches into saliva while you work, drive, or sit in a meeting. When you are done, you throw the wet pouch away.
Start with what Zyn is if you need the pouch explainer, or the format hub if you are still choosing a family. That is the product, and it is a good one at the job it was designed for. People land on Zyn versus BRST when the pouch itself has become the problem, or when they want oral nicotine that does not sit on the gum for most of an hour. BRST is a 2mg nicotine tablet that melts under the tongue. It is not a Zyn flavor and not a pouch in a different wrapper.
What follows is what a Zyn pouch actually is, what a published Zyn blood study measured after a full hour in the lip, and how a short-path tablet differs in the mouth and on the clock. Adults 21+ only. Nicotine is addictive. BRST is not FDA-approved nicotine replacement therapy.
What Zyn is, and what a nicotine pouch actually does
A modern nicotine pouch is a small, tobacco-leaf-free sachet. The fill is nicotine (often as a salt), plant fibers, pH adjusters, and flavor. You place it between the lip and the gum, usually up top. Saliva wets the bag, nicotine crosses the lining of the mouth, and a share gets swallowed. When the pouch is spent, you throw it away.
Zyn is the brand that made that ritual ordinary. The can fits a pocket. The lineup is broad. The use is quiet: no smoke, no vapor cloud, no lighter. You could keep nicotine in a workday, a flight, or a dinner without stepping outside.
The trade is time and anatomy. A pouch is a parked product. Typical use is 30 to 60 minutes on the same strip of gum. Pull it early and you left dose in the trash. Leave it for an hour and you get the published peaks below, plus whatever the gum line thinks of a wet sachet sitting there day after day.
That gum-line sit is the complaint that does not get fixed by buying a different mint. Another pouch brand still lives on the same tissue. If that does not bother you, Zyn is doing its job. If it does, you are shopping for a different place in the mouth.
What Lunell measured when people held Zyn for an hour
Zyn already has a serious blood study. In 2020, Lunell and colleagues published nicotine measurements on ZYN pouches in *Nicotine & Tobacco Research*. Adults held the pouch under the lip for 60 minutes. Researchers drew blood and later measured how much nicotine was left in the used pouch.
The 3mg ZYN Smooth pouch reached a peak of 7.7 nanograms per milliliter at 61 minutes. About 56 percent of the nicotine came out, roughly 1.5mg extracted. The 6mg pouch reached 14.7 nanograms per milliliter at 66 minutes, with about 59 percent extracted (about 3.5mg). The 8mg pouch, in a second part of the same paper, reached 18.5 nanograms per milliliter at 59 minutes, with about 50 percent extracted (about 3.8mg).
Read those clocks again before you read the heights. Three labeled doses. Three peak heights. Almost the same time to get there: 61, 66, and 59 minutes. Dose changed how high the curve went. It did not make the pouch fast.
Lunell’s own framing was that 6mg and 8mg ZYN deliver nicotine as quickly and as fully as existing smokeless products. “As quickly as snus” is still about an hour. A cigarette, in Benowitz’s 2009 review of venous nicotine, peaks in 5 to 8 minutes at 15 to 30 nanograms per milliliter. Zyn is a long-dwell oral product, and the blood data match the way you use it.
Researchers call minutes to the highest reading time to peak (Tmax) and the height of that reading peak concentration (Cmax). Here those words only mean clock and height. A higher peak is more nicotine in blood, not a trophy.
| Product | Dose | Minutes to peak | Peak in blood | Hold time in the study | Share extracted |
|---|---|---|---|---|---|
| ZYN Smooth | 3mg | 61 min | 7.7 ng/mL | 60 min under the lip | about 56% (1.5mg) |
| ZYN Smooth | 6mg | 66 min | 14.7 ng/mL | 60 min | about 59% (3.5mg) |
| ZYN | 8mg | 59 min | 18.5 ng/mL | 60 min | about 50% (3.8mg) |
Source: Lunell et al., 2020. These numbers describe Zyn held for an hour. They are not a BRST-versus-Zyn trial.
If you have ever “needed 6mg” because 3mg felt weak, Lunell is a picture of what you bought: a taller peak over the same long sit, not a shorter clock.
What a 2mg tablet does instead
BRST is a 2mg peppermint tablet. You place it under the tongue, back near the molars, and keep it still for about five minutes. It melts. There is no bag, no spit, and nothing to throw away. Ten ingredients. Made in a US facility. The design bet is simple: put a modest dose on thin tissue under the tongue, and 2mg can land.
That is a different mouth from Zyn. A pouch is buccal. It sits on thicker gum and cheek lining and drips into saliva you swallow. A melt is sublingual. The path into blood is shorter if you actually leave the tablet there. Chew it or wash it down and you turned a sublingual product into a swallowed one.
BRST’s published blood study is Rose et al., 2022, in *Psychopharmacology*. It is not a Zyn study. Six adults used a 2mg BRST tablet and, on another visit, a 2mg Commit lozenge.
The tablet reached its peak at 14 minutes. The lozenge reached its peak at 82.5 minutes. In the first four minutes, nicotine from the tablet rose at 0.4 nanograms per milliliter per minute. The lozenge was 0.0.
Peak heights were similar, not higher: 4.4 versus 5.3 nanograms per milliliter. Total exposure was lower for the tablet (949.5 versus 1189.9). The authors suggest that happens because some of a fast-dissolving tablet gets swallowed.
A larger group (24 adults) used the 2mg tablet after two hours without nicotine. Craving on a 0 to 4 scale fell from 2.6 to 1.0 at five minutes. They rated craving relief 4.2 out of 7, next to 4.6 for their usual cigarette. Heart rate rose 8.3 beats per minute. Those are felt-effect numbers next to a 14-minute peak, not a claim that 2mg matches a cigarette’s 15 to 30 nanograms per milliliter.
The honest cross-study line is this. A 2mg BRST tablet peaked at 4.4 nanograms per milliliter in Rose. A 6mg Zyn pouch peaked at 14.7 in Lunell. The tablet does not out-peak the 6mg can. The claim is the clock: 14 minutes versus about an hour, in two different papers. Nobody published a head-to-head blood trial of BRST versus Zyn.
The Rose write-up is on BRST pharmacokinetics. Class comparison: nicotine pouch versus tablet. All four formats: tablet versus gum, lozenge, and pouch.
Zyn versus BRST as a format, not a flavor swap
Zyn is a pouch you park. BRST is a tablet you place and leave alone. Adults who like the can, the lip, and a long sit should stay on a pouch. Adults who are done with that sit are shopping a melt.
| Zyn pouch | BRST tablet | |
|---|---|---|
| What it is | Tobacco-free nicotine pouch | 2mg sublingual melt |
| Where it sits | Upper lip and gum, often 30 to 60 min | Under the tongue, back near the molars, about 5 min |
| What you do | Pack, wait, toss a wet pouch | Place it, keep still, it disappears |
| Spit or trash | A used pouch | Nothing to toss |
| Gum line | Yes. That is the product | No pouch on the gum |
| Common US strengths | 3mg and 6mg (8mg in some markets) | 2mg |
| Flavor story today | A wide can lineup | Peppermint |
| Ingredients story | Pouch fill and flavor | 10 ingredients, US facility |
| FDA NRT | No | No |
| Published speed | About an hour in Lunell 2020 | 14 min in Rose 2022, versus a lozenge |
Zyn can size changes by market. Check the can in your hand. BRST sells one unit: a 2mg melt, 20 per pack.
The daily difference is easier to see in a room than in a table. On a flight you cannot vape, and you may not want a wet pouch in your lip for the hour after takeoff. A tablet goes under the tongue while the safety video plays. You keep still. It is gone before the drink cart.
In a meeting, a pouch can show as a bump in the upper lip. A melt sits back near the molars. Once it starts to dissolve, you are just a person who is not talking for a minute. On a gum line that is already sore, another mint can is still a sachet on the same tissue.
None of that makes BRST “safer than Zyn.” Both are nicotine. Neither is a cigarette. Neither is a medicine.
Is Zyn stronger than BRST?
“Stronger” is three different questions, and adults mash them into one.
On the can, 6mg is more nicotine than 2mg. That is labeled milligrams in the product. It is the number you can read without a lab.
On the blood peak, Lunell’s 6mg ZYN is higher than Rose’s 2mg BRST: 14.7 versus 4.4 nanograms per milliliter. If stronger means the highest reading in venous blood, the 6mg pouch wins that comparison. Say it plainly. Speed is the claim, not a taller Cmax.
On the clock, the tablet peaked about 50 minutes sooner in those papers (14 minutes versus 66). If stronger means “I felt it while I still needed it,” adults are talking about the rise, not the can. A customer coming off 6mg pouches put it this way: hard to tell 6mg pouch versus 2mg BRST. That line is about felt strength. It is not a claim that 2mg matched 14.7 nanograms per milliliter.
Azzopardi et al., 2022, helps keep the pouch class honest. Their 4mg peppermint pouch (not Zyn) reached 8.5 nanograms per milliliter at a median 60 minutes, tied with a 4mg lozenge at 8.3, and well above 4mg chew-and-park gum at 4.4. Pouches as a class are good at total dose over a long sit. They are not built for a 14-minute peak.
Do not reverse-engineer a 6mg can with three BRST tablets on day one. One 2mg melt is one 2mg melt. If you still want more after it has finished, a second tablet is how you dose.
Who should stay with Zyn, and who is shopping a tablet
Stay with Zyn if the pouch ritual is the point: a can in the pocket, a flavor catalog, a long sit you already tolerate. A tablet will feel like a loss if what you loved was the park.
Shop a tablet if the pouch is the friction. The gum is raw. You are tired of drip and of hunting for a trash can. You need something for a meeting, a flight, or a date without a visible bump. You want the fastest non-vape oral option we make, and you will keep a tablet still under the tongue for about five minutes. BRST is built for that second group: a short-path 2mg melt, peppermint, 20 per pack, no spit.
How to take a BRST tablet if you already use Zyn
Placement is the product. If you treat a melt like a mint or a gum, you will waste it.
1. Adults 21+ only. Read the warning. Nicotine is addictive. 2. The next time you would pack a pouch, put one 2mg tablet under the tongue, back near the molars. 3. Keep the tongue still for about five minutes. Let it melt. Do not chew it. 4. Skip food and drink while it sits. Water after it is gone, not before. 5. Wait. If you would have reached for a second pouch, wait until the melt has finished before you decide on a second tablet.
Keep a pack where the can used to live for a week so your hand has somewhere to go.
Shop BRST Nicotine Melts when you want the 2mg peppermint pack. The tablet is the unit. The clock is the pitch.
Frequently asked questions
Did anyone put BRST and Zyn in the same blood trial?
No. Zyn’s blood numbers on this page come from Lunell 2020. BRST’s come from Rose 2022 versus a 2mg lozenge. Different trials, different doses, different hold times.
Does Zyn peak faster if I use 3mg?
Not in Lunell. The 3mg pouch peaked at 61 minutes, almost identical to 6mg at 66 and 8mg at 59. Dose changed the height of the peak. It did not make the pouch fast.
Is BRST a Zyn alternative?
It is an adult oral nicotine product with a different route. It is not a Zyn flavor, not a pouch, and not a program for getting off Zyn. That is a shopping decision, not a medical claim.
Will I get the same feel as a 6mg Zyn?
Maybe, maybe not. Customers coming off 6mg pouches have said 2mg BRST is hard to tell apart on feel. On blood peak, 4.4 is not 14.7. Start with one tablet.
Can I use a pouch and a tablet on the same day?
You can overdo nicotine with any two oral products. One format at a time is the sane default while you learn the melt.
Does BRST have more flavors than Zyn?
No. Zyn wins the flavor wall. BRST is peppermint today. If the mint aisle is why you stay with a pouch, stay with the pouch.
A note on what this is (and is not)
BRST is a PMTA tobacco product for adults 21+. It is not FDA-approved nicotine replacement therapy, and this page is not medical advice. Nicotine is addictive. Cross-study blood numbers come from different trials, doses, and use protocols. The only published head-to-head blood study of BRST is Rose et al., 2022, versus a 2mg Commit lozenge.
