Understanding Erythritol
Erythritol is a sugar alcohol (polyol) that occurs naturally in some fruits, such as grapes, pears, and watermelon, as well as fermented foods like wine and cheese. For commercial production, it is typically derived from cornstarch through a fermentation process. Unlike other sugar alcohols like xylitol or sorbitol, erythritol is mostly absorbed into the bloodstream before reaching the large intestine, which means it causes significantly less digestive upset. It is a zero-calorie, zero-glycemic index sweetener that doesn't impact blood sugar or insulin levels, making it a popular choice for those managing diabetes or following low-carb and ketogenic diets.
The Role of Erythritol in Sweetener Blends
Pure erythritol is only about 70% as sweet as table sugar and has a distinct cooling sensation in the mouth. To counteract this and achieve a sweetness and texture more comparable to sugar, manufacturers often blend it with high-intensity sweeteners like stevia or monk fruit. The erythritol provides the bulk and texture that these highly concentrated sweeteners lack, resulting in a product that can be measured and used more like regular sugar.
Popular Blends and Standalone Sweeteners with Erythritol
Stevia-Erythritol Blends
Stevia is a natural, zero-calorie sweetener derived from the stevia plant. Its extract, steviol glycosides, can be up to 300 times sweeter than sugar but sometimes has a lingering, bitter aftertaste. To mask this and create a user-friendly product, brands blend stevia with erythritol.
- Truvia: A well-known brand, Truvia offers various products that contain erythritol, particularly its granulated options, which blend stevia leaf extract with erythritol to provide bulk and a clean, sugar-like taste.
- Splenda Naturals Stevia: Some of Splenda's natural sweetener products, specifically those containing stevia, are formulated with erythritol. However, it is important to note that the classic yellow Splenda packets, which use sucralose, do not contain erythritol.
- Natural Mate: This brand offers a granular stevia and erythritol blend that is marketed for keto and diabetic diets, highlighting its organic and non-GMO ingredients.
Monk Fruit-Erythritol Blends
Similar to stevia, monk fruit extract is a natural, intensely sweet, zero-calorie sweetener. Blending it with erythritol is a common practice to improve its texture and measureability.
- Lakanto Monkfruit Sweetener: One of the most prominent brands in this category, Lakanto, offers a range of products that are simply a mix of monk fruit extract and erythritol. It is often sold as a 1:1 sugar replacement for baking and cooking.
- Durelife: Another brand utilizing this combination, Durelife offers a monk fruit and erythritol blend designed for various low-carb and keto applications.
Standalone and Other Erythritol Products
Some sugar substitutes feature erythritol as the primary or even sole sweetener, sometimes blended with other polyols or sweeteners for improved performance.
- Swerve: This brand specializes in erythritol-based products and is particularly popular for baking because it measures cup-for-cup like sugar. Swerve blends erythritol with oligosaccharides and allulose for a taste profile that closely mimics sugar.
- Whole Earth Sweetener Co. and Anthony's: These are examples of brands that offer 100% erythritol, sold as a standalone crystalline powder for use in various applications.

Considerations and Recent Findings
While erythritol has been deemed Generally Recognized as Safe (GRAS) by the FDA for many years, recent studies have sparked new discussions about its potential health effects, particularly concerning heart health. A 2023 study published in Nature Medicine found an association between higher blood levels of erythritol and an increased risk of heart attacks and strokes. Laboratory studies have suggested erythritol may increase platelet activity, which could promote blood clot formation. It is important to note that these studies found an association and not causation. For individuals with pre-existing cardiovascular risk factors, or those with concerns, consulting with a healthcare provider is recommended.
For most people consuming erythritol in moderation, gastrointestinal side effects like bloating, gas, and diarrhea are the more common concern, though these are much less frequent with erythritol than with other sugar alcohols. As with any dietary change, paying attention to how your body responds is key. For more on erythritol's benefits and risks, see this guide from the Cleveland Clinic.
Conclusion
In summary, erythritol is a foundational ingredient in many modern zero-calorie sweeteners, particularly those seeking to mimic sugar's bulk and texture. It is a key component in blends with stevia (like Truvia) and monk fruit (like Lakanto), and is the star of standalone products like Swerve and 100% erythritol powders. Its minimal impact on blood sugar and low-calorie nature make it appealing for various dietary needs, including keto and diabetic management. However, recent scientific findings on its potential cardiovascular risks highlight the need for continued research and individual caution, especially for those with heart health concerns. Ultimately, the best choice depends on personal taste, dietary goals, and health considerations.
