This page is not medical advice. If you have diabetes, talk to your clinician or a registered dietitian about how protein bars fit into your meal plan. We make no claims about blood sugar or any health outcomes.
What we can give you is the label, checked. Below are the bars in our verified set whose product labels list 1 g of total sugars or less, sorted by total carbohydrate, lowest first. Each entry states total carbohydrate, fiber, sugar alcohols, and allulose exactly as printed, because total sugars alone does not show you a bar’s full carbohydrate content. We checked 25 verified bar listings; 9 meet the line.

How we chose
The rule: a bar is listed only when its nutrition panel for one named flavor is verified in our database with a last verified date, and the number that earns its place is the number printed on that panel. Every figure on this page is for the one flavor named, as printed; other flavors in the same line can differ. Verified dates in the set we checked run from Sep 22, 2026 to Oct 23, 2026. A verified date is the day a listing’s nutrition panel was checked against the brand’s label image or product page and marked verified in our database. Production and best-by dates are something else, and this page does not show them. The read date on each quote from the brand is the day we read the brand’s page for that line, a separate check. Three bars we track are not published yet and were left out of this page: Gatorade Recover Protein Bars, CLIF BUILDERS Protein Bar and Lenny & Larry’s Cookie-fied Bar. Protein powders are outside this bar list.
The “Contains” and “Cross-contact” lines under each bar are quoted from the maker’s product page as we read it on Oct 24, 2026, with where each one sits. A line can be for a different flavor from the one whose label we verified; each quote says what it covers. Where our listing’s own allergen field shows a line we did not find on the brand’s page, the entry shows that line too.
We do not compute a glycemic figure, and we do not rank bars for their potential effect on blood sugar. Readers with diabetes should talk to their clinician before changing what they eat.
