Are Protein Bars Really Low in Sugar?
Not all protein bars are low in sugar. Some bars marketed as “healthy” still contain 15–20 g of added sugar, which is close to a candy bar. Others keep sugar below 5 g and use alternatives like sugar alcohols, stevia, monk fruit, or allulose to add sweetness without the same calorie load.
Added sugar targets. The American Heart Association suggests no more than ~25 g of added sugar per day for most women and ~36 g for most men. A bar with 2–8 g added sugar can fit into most diets, but one with 15 g or more may use up most of your daily limit.
Sugar alcohols and allulose. Many low-sugar bars rely on erythritol, maltitol, or isomalto-oligosaccharides (IMOs). These provide fewer calories than sugar but can cause gas or bloating if you eat too much. Allulose is another popular choice—it counts toward total carbs but not added sugar, with only ~0.4 kcal per gram.
Natural sweeteners. Stevia and monk fruit are calorie-free and don’t raise blood sugar, but taste can vary. Some bars blend these with small amounts of sugar or fruit puree to improve flavor.
Bottom line. A protein bar is truly low in sugar if it:
- has 0–5 g added sugar per bar
- keeps total sugar under ~8 g per serving
- uses low-calorie sweeteners you tolerate well
- balances protein and fiber so it still feels satisfying
Always check the nutrition label since two bars with the same calories can have very different sugar and protein profiles. If sugar is one of the first ingredients, it’s not really a low-sugar bar.
