The short answer is yes — ZYN is gluten-free. The FDA has established a gluten limit of fewer than 20 parts per million (ppm) for foods that carry the label "gluten-free." The gluten level in ZYN pouches have been tested and shown to be less than 20 parts per million (ppm) per pouch. However, you should talk to your doctor before making decisions about using any unfamiliar gluten-free products.
