Zyn vs BRST: Pouch vs 2mg Nicotine Tablet
Zyn vs BRST: 3mg pouch 7.7 ng/mL at 61 min, 6mg 14.7 at 66 (Lunell). BRST 2mg tablet peaks at 14 minutes. Not a pouch. 21+.
Key Takeaways
Lunell 2020 (Zyn’s PK): 3mg 7.7 ng/mL at 61 min; 6mg 14.7 at 66; 8mg 18.5 at 59.
Dose changed Zyn’s peak height. It did not make Tmax fast.
BRST 2mg peaked at 14 min in Rose 2022. No BRST-vs-Zyn blood trial exists.
Zyn is a pouch. BRST is a melt. Different mouth, different clock.
BRST is an adult alternative, not a quit product and not FDA NRT. 21+.

Zyn is a tobacco-free nicotine pouch you park between the lip and gum. BRST is a 2mg sublingual melt. Lunell et al. 2020 is Zyn’s own published PK: 3mg peaked at 7.7 ng/mL in 61 minutes, 6mg at 14.7 ng/mL in 66 minutes, 8mg at 18.5 ng/mL in 59 minutes, each held for 60 minutes. BRST’s published PK (Rose et al. 2022) is 4.4 ng/mL in 14 minutes versus a 2mg lozenge.
Different studies. Different doses. Same lesson: Zyn is a high-dwell pouch. BRST is a short-path tablet. Adults comparing the two are usually choosing a clock and a place in the mouth, not two cans of the same thing.
Zyn vs BRST: the numbers Zyn already published
| Product | Dose | Tmax | Cmax | Study notes |
|---|---|---|---|---|
| ZYN Smooth | 3 mg | 61 min | 7.7 ng/mL | Lunell 2020; 60 min hold; ~56% extracted (1.5 mg) |
| ZYN Smooth | 6 mg | 66 min | 14.7 ng/mL | Lunell 2020; ~59% extracted (3.5 mg) |
| ZYN | 8 mg | 59 min | 18.5 ng/mL | Lunell 2020 part 2; ~50% extracted (3.8 mg) |
| General snus | 8 mg | — | — | ZYN 6mg AUC was 34% larger than 8mg General |
| BRST tablet | 2 mg | 14 min | 4.4 ng/mL | Rose 2022 vs Commit 2mg; not vs Zyn |
| Cigarette | 1 cig | 5–8 min | 15–30 ng/mL | Benowitz 2009 venous |
Lunell’s conclusion was that 6 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 is 5–8 minutes. BRST sits between them on Tmax, at a lower Cmax, on purpose. 2mg is enough when the tissue is under the tongue.
Format, not a flavor swap
| Zyn pouch | BRST tablet | |
|---|---|---|
| What it is | Tobacco-free pouch, nicotine salts in a bag | Patented 2mg sublingual melt |
| Where it sits | Upper lip / gum, often 30–60 min | Under the tongue ~5 min |
| Spit / discard | A wet pouch | Nothing to toss |
| Gum line | Yes | No |
| Common strengths | 3 and 6mg (8mg in some markets) | 2mg |
| Ingredients story | Pouch fill + flavor | 10 pharmaceutical ingredients, U.S. facility |
| FDA NRT | No | No |
| Published speed | Tmax ~1 hour (Lunell) | Tmax 14 min (Rose) |
Adults who used 6mg Zyn often say 2mg BRST is hard to tell apart on feel. That quote is about delivery, not about matching Lunell’s 14.7 ng/mL. If you want a long, numb gum-line sit, Zyn is the product that was designed for that. If you want the fastest non-vape oral we make, it is the melt.
Is Zyn “stronger” than BRST?
On the can, 6mg is more nicotine than 2mg. On Lunell’s Cmax, 6mg ZYN is higher than Rose’s 2mg BRST. On the clock, BRST peaks about 50 minutes sooner in those papers. Strength is three different questions. We answer the third one: BRST is built so 2mg can work.
Azzopardi’s 4mg pouch (not Zyn) tied a 4mg lozenge and beat 4mg gum. Pouches as a class are good at total dose over an hour. They are not good at a 14-minute Tmax. Cluster pages: tablet vs pouch, all four formats.
Try BRST 2mg peppermint melts. 20 per pack. No pouch, no spit.
Frequently asked questions
Did anyone put BRST and Zyn in the same PK 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.
Does Zyn peak faster if I use 3mg?
Lunell’s 3mg Tmax was 61 minutes, almost identical to 6mg (66) and 8mg (59). Dose changed Cmax. It did not make the pouch fast.
Is BRST a Zyn alternative?
It is an adult oral alternative with a different route. It is not a Zyn flavor, not a pouch, and not a quit-Zyn program.
What about Zyn’s MRTP language?
Zyn has its own FDA-authorized switching claims. BRST does not. It is an adult alternative, not a cessation product.
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 PK 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.
