Do Zyns Have Calories? Nutrition Facts for Nicotine Pouches (Sugar, Carbs, Fasting)
Zyn pouches contain less than 1 calorie each. The trace energy comes from filler ingredients like maltitol and microcrystalline cellulose, not from added sugar. There are zero grams of added sugar, less than 1% of the daily recommended carbohydrate allowance per pouch, and under 10 mg of sodium, per ZYN's own FAQ. For practical purposes, whether you are counting macros or fasting, a Zyn pouch is nutritionally negligible.
That said, "negligible" is not the same as "zero." Here is exactly what the numbers look like, where the trace calories come from, and how nicotine pouches compare to a zero-nicotine caffeine pouch if you are evaluating both.
Zyn Nutrition Facts per Pouch
| Nutrient | Amount per Pouch | % Daily Value (2,000 kcal diet) | Source |
|---|---|---|---|
| Calories | < 1 kcal | ~ 0% | ZYN USA FAQ |
| Total carbohydrates | < 1% DV | < 1% | ZYN USA FAQ |
| Sugar (added) | 0 g | 0% | ZYN USA FAQ |
| Sodium | < 10 mg | < 0.5% | ZYN USA FAQ |
| Fat | 0 g | 0% | Not listed on ZYN FAQ; inferred from ingredient profile |
| Protein | 0 g | 0% | Not listed on ZYN FAQ; inferred from ingredient profile |
| Nicotine | 3 mg or 6 mg | N/A (not a nutrient) | FDA |
Even if you use several pouches a day, the cumulative caloric impact stays in single digits. Ten pouches would still be under 10 kcal, less than a single sugar cube.
What Is Actually in a Zyn Pouch?
The ZYN USA FAQ lists the following ingredient categories:
- Nicotine salt (nicotine bitartrate dihydrate): pharmaceutical-grade nicotine
- Stabilizers (hydroxypropyl cellulose): plant-based food additive for pouch consistency
- Fillers (microcrystalline cellulose, maltitol, gum arabic): bulk agents that give the pouch its shape; maltitol is a sugar alcohol with roughly 2.1–2.4 kcal/g (depending on the regulatory framework), which accounts for most of the sub-1-calorie trace
- pH adjusters (sodium carbonate, sodium bicarbonate): minerals that help nicotine absorb through the gum lining
- Sweetener (acesulfame K): zero-calorie artificial sweetener, the same compound found in sugar-free gum and diet sodas
- Flavorings and humectants: vary by flavor
No table sugar. No high-fructose corn syrup. The sweetness you taste is acesulfame K, which contributes zero calories.
Do Zyns Have Sugar or Carbs?
No added sugar. The carbohydrate content per pouch falls below 1% of the daily recommended intake on a 2,000 kcal diet, per ZYN's FAQ. That trace amount comes from maltitol and cellulose, both of which are sugar-free fillers.
If you are tracking net carbs for a keto or low-carb protocol, a Zyn pouch is effectively zero. Maltitol does have a glycemic index (around 35, roughly half that of table sugar), but the quantity per pouch is so small that the glycemic impact rounds to nothing.
Does Zyn Break Intermittent Fasting?
From a strict calorie standpoint, no. A sub-1-calorie product will not trigger a meaningful insulin response or pull you out of a fasted metabolic state. A commonly cited (though not formally standardized) heuristic places the threshold at roughly 50 kcal before a fast is considered "broken" for fat-oxidation purposes, and Zyn sits far below that line.
There is a separate, pharmacological angle: nicotine itself can reduce appetite independent of calories. A 2011 study published in Science (Mineur et al.) demonstrated that nicotine decreases food intake in animal models through activation of hypothalamic POMC neurons. That is a drug effect, not a nutrition-label effect, and it is not a reason to use nicotine pouches as a fasting aid.
For a deeper look at fasting and oral pouches, see Zyn and fasting rules.
How Much Nicotine Is in a Zyn? Dose Context
On January 16, 2025, the FDA authorized 20 ZYN nicotine pouch products for marketing in the United States, the first-ever marketing authorization for a nicotine pouch. The authorized products come in two strengths: 3 mg and 6 mg of nicotine per pouch, across 10 flavors.
For context, a typical cigarette delivers roughly 1 to 2 mg of absorbed nicotine per use, though total nicotine content in the tobacco itself is higher. A 6 mg Zyn pouch releases its nicotine more slowly through the oral mucosa than smoke delivers it through the lungs. Nicotine is addictive regardless of the delivery method. If you have questions about appropriate use or dosage, talk to your clinician.
Zyn Calories vs. a Caffeine Pouch (Side-by-Side)
If you are researching pouches and calories, you may be comparing nicotine pouches to caffeine pouches. Here is how Zyn stacks up against Roon, a zero-nicotine caffeine pouch, on the nutrition label:
| Metric | Zyn (per pouch) | Roon (per pouch) |
|---|---|---|
| Calories | < 1 kcal | 0 kcal (zero sugar, zero calories) |
| Sugar | 0 g (sweetened with acesulfame K) | 0 g (sweetened with sucralose) |
| Carbohydrates | < 1% DV | ~ 0 g |
| Sodium | < 10 mg | Trace |
| Active ingredient | Nicotine (3 mg or 6 mg) | Caffeine (80 mg) + L-theanine, methylliberine, theacrine |
| Nicotine | Yes | None |
| Caffeine | None | 80 mg |
| FDA status | Authorized tobacco product (2025) | Dietary supplement |
Both products are effectively zero-calorie and zero-sugar. The difference is the active ingredient, not the nutrition label. For a full ingredient and experience comparison, see Zyn vs a caffeine pouch.
Putting the Numbers in Perspective
Whether you use Zyn, a caffeine pouch, or both, the calorie contribution from an oral pouch is a rounding error in any diet. A single almond has about 7 kcal. A Zyn pouch has less than 1. If you are optimizing for macros, fasting windows, or keto compliance, nicotine pouches and caffeine pouches alike sit firmly in the "don't worry about it" category on the calorie front.
The bigger questions around pouch use have nothing to do with the nutrition label. They involve nicotine dependence risk (for Zyn), caffeine tolerance management (for any caffeine product), and whether the active ingredient serves your goals. The calorie question, at least, has a simple answer: it is effectively zero.
Frequently Asked Questions
Do nicotine pouches have carbs?
Zyn pouches contain less than 1% of the daily recommended carbohydrate allowance per pouch, per ZYN's FAQ. The trace carbs come from filler ingredients like maltitol and microcrystalline cellulose, not from sugar. For any practical dietary purpose, the carb content is negligible.
Are Zyn pouches keto-friendly?
Yes, for calorie and carb purposes. A sub-1-calorie product with near-zero carbohydrates will not interfere with ketosis. Maltitol does have a modest glycemic index compared to other sugar alcohols, but the amount per pouch is too small to matter.
Do Zyns have caffeine?
No. Zyn pouches contain nicotine, not caffeine. If you want a pouch with caffeine instead, products like Roon use caffeine as the active ingredient with no nicotine. The two are different stimulant categories with different mechanisms and risk profiles.
Does Zyn have sugar?
No added sugar. Zyn is sweetened with acesulfame K, a zero-calorie artificial sweetener. The only carbohydrate-adjacent ingredient is maltitol (a sugar alcohol used as a filler), and it contributes a fraction of a calorie per pouch.
How many calories are in 10 Zyns?
Fewer than 10 kcal total. Each pouch is under 1 kcal, so even heavy use stays well below the calorie count of a single cracker.
Does nicotine itself have calories?
Nicotine is a chemical compound, not a macronutrient. It provides no caloric energy. Its effects on appetite and metabolism are pharmacological, mediated through receptors in the brain, not through caloric content (Mineur et al., 2011).
Can I use Zyn while counting macros?
From a macro-tracking standpoint, Zyn does not meaningfully contribute to your protein, fat, or carbohydrate totals. Most nutrition tracking apps either do not list Zyn or list it as zero. You do not need to log it.
Is there a calorie difference between Zyn 3 mg and Zyn 6 mg?
No. The nicotine strength (3 mg vs. 6 mg) affects nicotine dose, not calorie content. The filler, sweetener, and structural ingredients are the same across strengths, and the calorie content is under 1 kcal for both.
If You Want Zero Calories and Zero Nicotine
Both Zyn and Roon land at effectively zero calories. The difference is what they do, not what they weigh on a nutrition label.
Roon is a zero-nicotine caffeine pouch built for focus, not a nicotine product. Each pouch combines 80 mg caffeine, 60 mg L-theanine, 25 mg methylliberine (Dynamine), and 5 mg theacrine (TeaCrine) in a sublingual format. Zero sugar, zero calories, sweetened with sucralose. The felt window is 6 to 8 hours. Tins start from $9.16 (12-tin subscription), working out to as little as $0.61 per pouch.
Roon is not a substitute for Zyn and does not contain nicotine. It is a different category entirely. But if you landed on this page because you are evaluating what goes into your body during a fast or a calorie deficit, and you want an oral pouch with a stimulant that is not nicotine, it is worth a look.
