Sugar Alcohols List: Types, Names, and Label Reading

What are sugar alcohols, and why do they matter on labels?

Sugar alcohols are a category of low-calorie sweeteners that food manufacturers use as partial or full replacements for table sugar. They provide sweetness with fewer calories and a lower glycemic impact than regular sugar, which is why you find them in products marketed as "sugar-free," "reduced sugar," or "diabetic-friendly." If you have ever flipped over a protein bar or a piece of sugar-free gum and spotted a name you could not quite place, there is a good chance it was a sugar alcohol.

Despite the name, sugar alcohols are neither sugars nor alcoholic. They are a class of carbohydrates called polyols, and the FDA requires them to be listed in the nutrition facts panel under total carbohydrates when a manufacturer makes a sugar-free or no-sugar-added claim on the package.

The full sugar alcohols list: common names you will see on US labels

Knowing the sugar alcohol names that appear on ingredient lists makes label reading much faster. Here are the ones you are most likely to encounter in US grocery stores:

Sorbitol

One of the oldest polyols, sorbitol appears in sugar-free candies, chewing gum, and some baked goods. It provides about 2.6 calories per gram compared to sugar's 4. It is also used as a humectant to keep products moist.

Xylitol

Xylitol is widely used in sugar-free gum, mints, and some peanut butters. It has roughly 2.4 calories per gram and a glycemic index close to zero. It is well studied for dental health benefits, with some evidence suggesting it may reduce cavity-causing bacteria. Important note for pet owners: xylitol is highly toxic to dogs, and the FDA has flagged this risk.

Erythritol

Erythritol has become one of the most popular sugar alcohols in recent years, appearing in keto-friendly snacks, protein bars, and low-sugar drinks. It contains almost zero calories because most of it is absorbed in the small intestine and excreted unchanged. A 2023 study published in Nature Medicine raised questions about a possible association between high erythritol blood levels and cardiovascular risk, though researchers noted that the body also produces erythritol naturally and that causality has not been established. The science is still developing, and consumers with existing heart concerns may want to follow updates.

Maltitol

Maltitol is common in sugar-free chocolate and candy because it behaves similarly to sugar in cooking. However, it has a higher glycemic index than most other sugar alcohols, around 35, which means it raises blood sugar more than alternatives like erythritol or xylitol. People managing blood glucose should check for maltitol specifically.

Mannitol

Mannitol shows up in some chewing gums and pharmaceutical products. It is less commonly used in mainstream grocery items but can appear in specialty or imported products.

Isomalt

Isomalt is used in hard candies and sugar-free cough drops. It is derived from beet sugar and has about half the calories of regular sugar.

Lactitol

Lactitol is less common in everyday grocery products but appears in some European-style cookies and chocolate. It is derived from lactose, so people with dairy sensitivities should take note.

Hydrogenated starch hydrolysates (HSH)

This is a catch-all term for a mixture of polyols produced by partial hydrolysis of starch. You may see it listed on sugar-free candy labels without a more specific name.

Where do sugar alcohols show up in US grocery stores?

The types of sugar alcohols above appear across a wide range of product categories. Here is where you are most likely to encounter them on a typical grocery run:

• Sugar-free gum and mints (xylitol, sorbitol, isomalt) at checkout aisles in Target, Walmart, and Costco
• Protein bars and keto snacks (erythritol, maltitol) at Whole Foods, Trader Joe's, and online
• Sugar-free chocolate and candy (maltitol, isomalt, sorbitol) in the candy aisle or specialty section
• Low-carb baked goods and bread (erythritol, xylitol) at natural food stores
• Flavored protein drinks and powders (erythritol) increasingly common across all retailers
• Sugar-free ice cream and frozen desserts (sorbitol, erythritol, maltitol)

If you are already reading labels on low sugar snacks at US grocery stores, you have almost certainly walked past several products containing these ingredients.

What does the FDA say, and what does the evidence actually show?

The FDA classifies most sugar alcohols as generally recognized as safe (GRAS) or approves them as food additives. They are permitted for use in the United States, and the FDA requires that sugar alcohols on labels be disclosed in the nutrition facts panel.

The most consistent and well-established side effect is gastrointestinal discomfort. Because polyols are not fully absorbed in the small intestine, they pass into the large intestine where gut bacteria ferment them, potentially causing bloating, gas, or a laxative effect. The European Food Safety Authority (EFSA) notes that consumption of foods containing polyols above certain thresholds may produce laxative effects, and US labeling rules allow a similar warning on products where a reasonable daily intake of the food would deliver more than 50 grams of polyols.

For most people eating these ingredients in typical amounts, the digestive effects are mild and dose-dependent. Children and people with irritable bowel syndrome may be more sensitive.

The erythritol cardiovascular study mentioned above generated significant media coverage in 2023, but nutrition researchers have urged caution about overinterpreting observational data. The NIH National Library of Medicine hosts the study for anyone who wants to read the methodology directly. More research is ongoing.

For context on how sugar alcohols fit into the broader picture of sweetener alternatives, the evidence comparison in stevia vs monk fruit covers two other common low-calorie sweetener categories.

How to read labels for sugar alcohols

Here are practical steps for spotting and evaluating sugar alcohols during your next grocery trip:

1. Check the nutrition facts panel first. If a product makes a sugar-free claim, look for a "Sugar Alcohols" line under Total Carbohydrates. The grams listed there tell you the total amount across all polyols in the product.
2. Read the ingredient list for specific names. The nutrition panel gives you the total, but only the ingredient list tells you which sugar alcohol or combination of sugar alcohols is used.
3. Watch for maltitol in diabetic-friendly products. Its higher glycemic index means it may affect blood sugar more than the "sugar-free" label implies.
4. Consider your digestive sensitivity. If you or your kids are prone to bloating, check the serving size and realistic portion before buying in bulk.
5. Keep xylitol products away from dogs. This is a straightforward safety point the FDA has highlighted.

Conclusion

Sugar alcohols are a well-established class of ingredients with a range of names, calorie levels, and digestive tolerances. Most are FDA-approved and safe for typical consumption, but the specific type matters more than the broad category. Maltitol behaves differently from erythritol, and xylitol carries a specific pet safety concern. Reading past the front-of-pack claim to the actual ingredient list is the most reliable way to know what you are getting. If decoding polyol names on every label sounds exhausting, the Osana app can scan the barcode and flag sugar alcohols and other additives for you instantly.

Frequently asked questions

Are sugar alcohols safe for children?

Most sugar alcohols are considered safe for children in moderate amounts, but kids tend to be more sensitive to the laxative effects. Products with high amounts of sorbitol or maltitol can cause digestive upset at lower doses in children than in adults.

Do sugar alcohols count as carbs on a nutrition label?

Yes. The FDA classifies sugar alcohols as carbohydrates, and they appear under the Total Carbohydrates section of the nutrition facts panel. Some low-carb dieters subtract sugar alcohol grams from total carbs to calculate "net carbs," but this is not an FDA-defined term.

Which sugar alcohol is least likely to cause digestive issues?

Erythritol is generally considered the best-tolerated sugar alcohol because most of it is absorbed before reaching the large intestine. Sorbitol and maltitol are more likely to cause bloating or a laxative effect at higher doses.

Is erythritol dangerous because of the 2023 heart study?

The 2023 Nature Medicine study found an association between higher blood erythritol levels and cardiovascular events, but it was observational and could not prove causation. Researchers also noted that the body produces erythritol naturally. The science is still evolving, and no regulatory agency has changed its safety classification based on this single study.

How can I tell if a product has multiple sugar alcohols?

The nutrition facts panel shows a combined total for all sugar alcohols in the product. To see which specific ones are used, you need to read the ingredient list, where each polyol will be named individually.

Are sugar alcohols the same as artificial sweeteners?

No. Sugar alcohols are polyols derived from sugars or starches and contain some calories. Artificial sweeteners like aspartame or sucralose are high-intensity sweeteners with essentially zero calories and a completely different chemical structure.
