Zyn pouches contain zero sugar. The sweet taste you notice comes entirely from two artificial sweeteners, not from any form of table sugar, fructose, or glucose. Each pouch has roughly 1 calorie and 1 gram of total carbohydrates, making the sugar content effectively nonexistent.
What Makes Zyn Taste Sweet
Zyn uses two artificial sweeteners: acesulfame potassium and sucralose. Both are FDA-approved and commonly found in diet sodas, protein powders, and sugar-free gum. They’re intensely sweet, somewhere between 200 and 700 times sweeter than table sugar, so only tiny amounts are needed. A Duke University study found that acesulfame potassium was present in Zyn pouches at levels of just 0.3 to 0.9 mg per pouch, even in varieties labeled as unflavored.
That’s worth repeating: even the “unflavored” Zyn pouches contain a small amount of artificial sweetener. The researchers suggested these sweet compounds may play a role in making nicotine products more palatable and encouraging continued use.
Full Ingredient List
Beyond the two sweeteners, Zyn pouches contain nicotine (in a salt form called nicotine bitartrate dihydrate), plant-based fibers that form the pouch material, sodium carbonate and sodium bicarbonate to adjust pH, natural and artificial flavorings, gum arabic as a binder, water, a preservative (potassium sorbate), and maltodextrin. Maltodextrin is a carbohydrate derived from starch, which likely accounts for that 1 gram of carbs per pouch, but it is not sugar in the conventional sense.
Why the pH Matters More Than Sugar
If you’re asking about sugar because you’re concerned about your teeth, the more relevant factor with Zyn is its pH level. Testing published in the journal Tobacco Control found that oral nicotine pouches have a median pH of 8.8, which is alkaline. Manufacturers design them this way on purpose: at pH levels above 8, nicotine changes to a “free-base” form that passes through the lining of your mouth faster, delivering nicotine into your bloodstream more efficiently.
An alkaline environment is actually the opposite of what causes tooth decay. Cavities form when bacteria in your mouth feed on sugar and produce acid, dropping the pH below about 5.5. Since Zyn contains no sugar and sits on the alkaline side, it doesn’t create the acidic conditions that erode enamel. The FDI World Dental Federation classifies both acesulfame potassium and sucralose as non-cariogenic, meaning they don’t contribute to cavities. That said, holding any pouch against your gum tissue for extended periods can still irritate the soft tissue, which is a separate concern from sugar-related decay.
Nicotine and Blood Sugar
Even though Zyn itself is sugar-free, nicotine can affect how your body handles blood sugar over time. Research published in the American Heart Association’s journal Circulation found that long-term use of nicotine gum was associated with insulin resistance, a condition where your cells respond less effectively to insulin. The degree of insulin resistance correlated with how much nicotine was in participants’ blood. The researchers concluded that nicotine itself, not the other chemicals in cigarette smoke, is likely the main driver of these metabolic changes.
This doesn’t mean a single Zyn pouch will spike your blood sugar. But if you use nicotine pouches regularly over months or years, the nicotine may gradually affect your body’s ability to regulate glucose. For anyone managing diabetes or prediabetes, this is a more meaningful concern than the zero grams of sugar on the label.
