Hormbles primarily uses a milk-based protein blend of whey protein isolate and milk protein isolate, with some formulas also containing whey protein concentrate. Core bars provide 10 grams of protein per serving.

The core Milk Chocolate, Salted Fudge, and Peanut Butter bars contain 0 grams of sugar. Instead of conventional sugar, the formulas use ingredients including allulose, monk fruit extract, and stevia extract for sweetness. Newer caramel-nougat varieties contain less than 1 gram of sugar per serving.

Ingredients vary by flavor. Common ingredients include whey and milk protein, allulose, chocolate or cocoa, cocoa butter, palm or palm-kernel oil, shea-kernel oil, sunflower lecithin, natural flavors, monk fruit, and stevia. Peanut Butter varieties also contain peanuts and peanut flour.

All current core Hormbles products contain milk. Peanut Butter products also contain peanuts. Depending on the flavor, products may also carry warnings for possible contact with soy, tree nuts, wheat, egg, and sesame, so customers with allergies should review each package carefully.

Hormbles recommends keeping its candy in a cool, dry place. Because chocolate can melt during warm weather, the company ships orders with insulation and ice packs during the warmer months.

Hormbles states that its candy is manufactured in the United States. The company is based in Chicago, Illinois, but it does not publicly identify the state or facility where every product is manufactured, so a more specific production-location claim should not be used without confirmation.
