What is Erythritol?
Erythritol is a four-carbon sugar alcohol found naturally in small amounts in fermented foods, certain fruits, and some fungi. Commercially, it is produced by fermenting glucose with specific yeasts. Unlike most sugar alcohols, it is almost entirely absorbed in the small intestine and excreted unchanged in urine, which accounts for its low calorie value.
What does it do in the product?
In food and drink, erythritol provides sweetness without contributing meaningful calories or raising blood glucose in the way table sugar does. It also adds bulk and mouthfeel, making it useful in baked goods where sugar replacement would otherwise leave a hollow texture. Manufacturers often blend it with high-intensity sweeteners like stevia or monk fruit to round out flavor, since erythritol on its own can have a mild cooling sensation on the tongue.
Where you usually find it
- Sugar-free chewing gum and mints
- Low-calorie sports drinks and flavoured waters
- Keto-friendly baked goods and protein bars
- Stevia-sweetened beverages and yogurts
- Reduced-sugar chocolate and confectionery
Is Erythritol something to worry about?
For most people, erythritol is well tolerated at typical dietary amounts and has a long established safety record with regulatory bodies in both the US and EU. Because it is mostly absorbed before reaching the colon, it causes less digestive distress than other sugar alcohols such as sorbitol or maltitol, though very high single-serving doses can still cause mild discomfort in some individuals. A large observational study published in the mid-2020s raised questions about a possible association between high blood erythritol levels and cardiovascular risk, but researchers and regulators noted this was associational rather than causal, and that the body also produces erythritol endogenously; the science remains unsettled and ongoing.
Who should pay attention
- People sensitive to sugar alcohols may experience bloating or loose stools at large servings
- Those monitoring carbohydrate intake should note erythritol is often counted as zero net carbs, but individual metabolic responses vary
- Individuals with existing cardiovascular concerns may wish to follow evolving research on this ingredient
- People with rare inherited disorders of carbohydrate metabolism should consult a clinician before consuming sugar alcohols regularly
- Anyone managing diabetes should be aware that blended sweetener products containing erythritol may still include other carbohydrates
How is it regulated?
In the United States, the FDA classifies erythritol as Generally Recognized as Safe (GRAS), permitting its use across a wide range of food categories. In the European Union it holds the approved food additive designation E968, with permitted use governed by specific category limits under EU food additive regulations. Both jurisdictions require it to be declared by name in the ingredient list when used as an additive.
How to spot it on a label
On a product label, erythritol appears as 'erythritol' or, in EU-regulated markets, may be accompanied by the code E968, typically listed among sweeteners in the ingredient declaration. Labels using terms like 'sugar-free,' 'no added sugar,' or 'keto-friendly' are strong signals that erythritol or another sugar alcohol is present. When it appears alongside monk fruit extract or steviol glycosides, the two are functioning as a complementary system to mask each other's off-notes.
What a cleaner swap looks like
If you prefer to avoid erythritol entirely, look for products sweetened with small amounts of plain fruit juice, raw honey, or maple syrup, which offer a more familiar nutritional profile alongside their sweetness. For zero-calorie options, monk fruit extract used on its own is a common alternative with a similarly short safety record. Bear in mind that any sweetener swap changes the calorie and carbohydrate content of the product, so check the nutrition panel alongside the ingredient list.
