Zyn pouches are tobacco leaf free but not nicotine free, combining pharmaceutical grade nicotine salt with food grade fillers such as microcrystalline cellulose and plant based fibers, pH adjusters like sodium carbonate, sweeteners including acesulfame K and xylitol, stabilizers, salt, water, and added flavorings, all sealed inside a non-woven cellulose pouch. The amount of nicotine, typically 3 mg or 6 mg per pouch, and the way these ingredients affect your gums, blood pressure, and dependence risk vary more than the label suggests, so there are several important factors to consider below. Mouth irritation, gum recession, sore throat, nausea, headaches, and heart rate changes are among the reported effects, and some symptoms point to issues unrelated to pouch use entirely. See below for the full ingredient breakdown and what each component does in your body.
If you are noticing mouth sores, jaw pain, dizziness, nausea, or an elevated heart rate and you are not sure whether nicotine pouches are the cause, guessing is the slowest path to relief. A free, instant, online symptom check walks you through your specific symptoms in a few minutes, helps you understand which possible conditions match your pattern, and shows you what kind of care to seek next so you can stop worrying and start acting.

Zyn pouches are a popular brand of tobacco-free nicotine pouches. Instead of tobacco leaf, they deliver nicotine through a small, teabag-like pouch that you place between your gum and lip.
