Each bar receives an ingredient quality grade from A (Clean) to F (Avoid) based on a score calculated from its ingredient list. Ingredients are mapped to quality scores from +4 (excellent) to -4 (harmful) and weighted by their position in the list. Earlier ingredients are present in larger quantities and contribute more to the score. See the full methodology on our ingredient scoring page.
Sugar alcohols like erythritol and maltitol are generally recognized as safe but can cause digestive discomfort, bloating, and a laxative effect in some people, particularly in larger amounts. Maltitol has a notably higher glycemic impact than other sugar alcohols. Our scoring system treats sugar alcohols as a concern, with severity depending on how prominently they appear in the ingredient list.
