Is peanut butter gluten free?

Pure, traditional peanut butter made solely from roasted peanuts and salt is naturally gluten-free. Peanuts belong to the legume family and contain no gluten proteins. Consequently, most standard commercial peanut butters are completely safe for individuals living with celiac disease or non-celiac gluten sensitivity.

However, potential risks arise from added ingredients and factory cross-contamination. Flavored peanut butter spreads, pretzel-infused varieties, or products with malt flavorings can introduce gluten. Additionally, shared manufacturing lines may lead to trace contamination. If you have celiac disease, choose brands explicitly labeled “Certified Gluten-Free” and avoid shared kitchen jars where breadcrumbs can contaminate the peanut butter.
