Best low-sugar protein bars: the verified list

This page lists protein bars with verified nutrition panels listing 1 g of total sugars or less per bar. The 1 g line is our own choice and has no legal standing. We checked 25 verified bar listings; the 9 below meet it, lowest sugar first, then lowest total carbohydrate.

Sugar, sugar alcohols and allulose

Total sugars is one line on the Nutrition Facts panel. Many low-sugar bars are sweetened with sugar alcohols (such as erythritol or maltitol), which the panel includes on a separate line when the maker lists them, or with allulose, which some labels show only outside the panel; the entry says where this information is located. Neither is counted in total sugars. Each entry below shows those lines as the label does, so you can see what replaces the sugar.

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 includes that line too.

A 0 on this page means the panel lists 0 g. A panel line that reads “<1 g” is shown as “<1 g”; we do not round it down to 0.
