The Problem with Sugar Alcohols in Protein Bars
For years, many protein bars marketed as 'low-sugar' or 'sugar-free' have relied heavily on sugar alcohols such as maltitol, erythritol, sorbitol, and xylitol. While these ingredients provide sweetness with fewer calories than sugar and don't contribute to tooth decay, they often cause gastrointestinal issues. Because the human body doesn't fully absorb them, they can ferment in the gut, leading to bloating, gas, cramping, and diarrhea for many people. Some research has also raised concerns about potential links between certain sugar alcohols, like erythritol, and cardiovascular issues in at-risk individuals, though more study is needed.
Why manufacturers use them
Manufacturers use sugar alcohols for several reasons:
- Calorie Reduction: They offer sweetness at approximately half the calories of regular sugar, helping brands meet 'low-calorie' or 'keto-friendly' claims.
- Texture and Moisture: Sugar alcohols like glycerin also function as humectants, helping maintain a soft, moist texture in bars that would otherwise be hard and dry.
- Lower Glycemic Impact: Since they are not fully absorbed, they typically cause a smaller blood sugar spike compared to regular sugar, making them attractive for diabetics and those managing blood glucose.
Leading Brands That Avoid Sugar Alcohols
If you have a sensitive stomach or simply prefer to avoid highly processed ingredients, a number of brands have focused on creating cleaner protein bars. They often use natural sweeteners like stevia or monk fruit, or rely on the natural sweetness of whole foods such as dates and fruits.
IQBAR
IQBARs are a standout in the sugar alcohol-free category. They are plant-based, keto, and paleo-friendly, and are free from sugar alcohols, gluten, and dairy. They use a blend of brain-boosting nutrients and minimal, naturally occurring sugar for sweetness, avoiding synthetic additives completely.
ALOHA
ALOHA offers a popular line of organic, plant-based protein bars that explicitly state they are made without sugar alcohol sweeteners. Their bars rely on a short list of organic, whole-food ingredients, providing a clean and easily digestible option.
RXBAR
Known for its minimalist approach, RXBAR has built a brand identity around simple ingredients. Their protein bars famously list their core components—egg whites for protein, dates for binding and sweetness, and nuts for texture—right on the front of the wrapper. They contain no added sugar, artificial sweeteners, or sugar alcohols.
B.T.R Nation
B.T.R Nation specializes in keto superfood protein bars that are both plant-based and free of sugar alcohols. Their recipes often feature functional ingredients like adaptogens to provide added benefits beyond just protein.
Raw Rev Glo
Raw Rev Glo offers bars that, while using some lower-glycemic sweeteners, are designed with minimal processing and often avoid sugar alcohols, making them a suitable choice for many sensitive individuals. Always check the specific flavor ingredients, as formulations can vary.

How to Find a Protein Bar Without Sugar Alcohol
- Read the Ingredients List: The most critical step is to read the ingredient list, not just the nutrition facts. Look for any words ending in '-itol', such as erythritol, maltitol, and sorbitol. Also, check for 'glycerin', which is a type of sugar alcohol used for moisture and sweetness.
- Look for Whole-Food Sweeteners: Brands that don't use sugar alcohols often use whole-food ingredients like dates, figs, or fruit purees for sweetness and binding.
- Search for Alternative Sweeteners: Some brands utilize alternative, natural sweeteners like stevia or monk fruit, which do not fall into the sugar alcohol category.
- Prioritize Brands with Short Ingredient Lists: A shorter, more recognizable ingredient list is often a strong indicator that the bar is less processed and less likely to contain hidden synthetic additives.
- Be Wary of 'Net Carb' Marketing: The 'Net Carbs' calculation often subtracts sugar alcohols, making a product seem healthier on the front of the packaging. Always check the full nutrition facts.
The rise of clean labels
Growing consumer awareness about the potential side effects of sugar alcohols and artificial ingredients has led to a surge in 'clean label' products. Brands like ALOHA and RXBAR have built a strong market presence by embracing simplicity and transparency. This trend benefits consumers who prioritize natural, whole-food nutrition over synthetic shortcuts, providing a wider array of high-quality, sugar alcohol-free options.
Conclusion
Finding protein bars without sugar alcohol is very possible, with many brands offering cleaner, more natural alternatives. By reading ingredient labels carefully and prioritizing bars with whole-food ingredients or natural sweeteners like monk fruit and stevia, consumers can avoid digestive discomfort and other potential issues associated with sugar alcohols. Brands like IQBAR, ALOHA, and RXBAR demonstrate that it is possible to create a delicious and satisfying protein bar without relying on these processed additives. While convenient, remember that no protein bar should completely replace whole, unprocessed foods in a balanced diet. For those with specific health concerns, consulting a registered dietitian is always recommended.
