Arm & Hammer and Other Brands of Gluten-Free Baking Soda

Celiac.com 08/14/2021 - We get a lot of questions from celiac community members wondering if certain products are gluten-free. We especially get a lot of questions about baking ingredients like baking soda.  Specifically, what brands of baking soda are gluten-free and safe for people with celiac disease?

Baking soda is sodium bicarbonate. Per Wikipedia, "Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3." As a general rule, baking soda does not contain gluten ingredients, and can be regarded as gluten-free and safe for people with celiac disease. 

Celiac.com Sponsor (A12):
One thing to note is that some baking sodas are intended for cleaning, and are not food grade. Make sure the baking soda you plan to use for baking is food grade. Major brands you buy in the baking section grocery stores are always food grade. If you find it in the cleaning section, be sure to double check. For example, Arm & Hammer 33200-01670 Baking Soda is a cleaning grade form of baking soda that comes in a big plastic dispenser, while the standard box you find on the baking aisle is the food grade version. Cleaning grade baking soda probably won't harm you, but it may not provide the same results for baking as a food grade version.
