GLUTEN FREE CONFIDENCE SCORE: 5/10

When it comes to gluten-free options, Slimfast lands right in the middle. The brand offers a handful of products that do not contain gluten, including snack bars, meal protein bars, shake mixes, and meal shakes. However, the company does not offer a comprehensive list of their gluten free offerings and lack a gluten free certification. Certain products do not contain gluten ingredients, but the allergen information states that it may contain traces of wheat. For this reason, it is crucial that you carefully read the label of all Slimfast products before you purchase. Ingredients and manufacturing processes can change, so please read the ingredient and nutrition label carefully.  Need help in understanding what to look for on those labels?
