Understanding Erythritol: The Bulking Agent in Sugar-Free Sweeteners
Erythritol is a type of carbohydrate known as a sugar alcohol, or polyol, that is used as a sugar substitute. It is naturally found in small amounts in some fruits and fermented foods like grapes and cheese. For commercial use, however, erythritol is produced on a larger scale through the fermentation of a simple sugar, like dextrose from corn.
Unlike other sugar alcohols, erythritol is almost completely absorbed in the small intestine and then excreted unchanged in the urine, meaning it provides virtually no calories and doesn't affect blood glucose levels. The sweet components of sweeteners like stevia and monk fruit extract are hundreds of times sweeter than table sugar, meaning only a tiny amount is needed to achieve the desired sweetness. For this reason, manufacturers add bulking agents to give the product a sugar-like texture, volume, and appearance. Erythritol is an ideal choice for this purpose because it tastes similar to sugar, doesn't have a bitter aftertaste, and dissolves easily.
Popular Brands That Use Erythritol
Many zero-calorie sweeteners contain erythritol, either as the primary ingredient or as a bulking agent. This is especially true for brands that market themselves as natural, keto-friendly, or low-carb alternatives to sugar. Consumers should always check the ingredient list, as some brands offer a variety of products, with some formulations containing erythritol and others not.
Truvia
- Truvia Calorie-Free Sweetener: This is one of the most widely known sweeteners containing erythritol. It is a blend of stevia leaf extract, erythritol, and natural flavors.
- Truvia Sweet Complete: This line of products, including the granulated and brown varieties, also uses a blend of stevia leaf extract and erythritol, with molasses added to the brown sugar version.
- Note: Truvia Liquid Sweeteners do not contain erythritol, so checking the label is essential.
Splenda
- Splenda Naturals Stevia: This natural stevia-based product uses erythritol as a bulking agent. It is distinct from the classic yellow Splenda packets and granulated products, which do not contain erythritol.
- Other Splenda products: The Splenda brand has a wide range of sweeteners, and some of their newer products, particularly those marketed as natural or keto-friendly, incorporate erythritol.
Lakanto
- Lakanto Monk Fruit Sweetener: A very popular monk fruit and erythritol blend that is marketed as a zero-calorie, zero-glycemic alternative to sugar. It is available in classic white and golden versions, which can be used for cooking, baking, and sweetening beverages.
Swerve
- All Swerve products: The Swerve brand is built around its erythritol-based sweetener blends. The product line includes granular, powdered, and brown sugar alternatives, all of which use erythritol combined with oligosaccharides, which are a type of prebiotic fiber.
NOW Foods
- NOW Foods Real Food Erythritol: This brand sells 100% pure erythritol in granular and powdered forms, without any added intense sweeteners.
Health Garden
- Health Garden Erythritol: This brand sells pure erythritol, along with blends that combine erythritol with stevia.
Wholesome Sweeteners
- Wholesome Organic Stevia: This product uses organic erythritol blended with organic stevia for a smoother sweetness.
Why is Erythritol Used in Blended Sweeteners?
Erythritol serves several important functions in blended zero-calorie sweeteners, making it a favorite among food manufacturers.
- Adds Bulk and Volume: Intense sweeteners like stevia and monk fruit are so potent that they cannot be used in a 1:1 ratio like sugar. Erythritol provides the necessary bulk, allowing these products to measure and function similarly to table sugar in recipes.
- Improves Texture: Erythritol has a crystalline structure similar to sugar, which improves the texture of the final product, especially in baked goods and beverages.
- Masks Aftertaste: Some high-intensity sweeteners can have a bitter or metallic aftertaste. Erythritol's clean, sugar-like taste helps to mask these off-notes, resulting in a more palatable product.
- Low Glycemic Impact: For those managing blood sugar levels, erythritol is a preferred bulking agent because it does not cause a spike in blood sugar or insulin.

Potential Health Considerations
While erythritol is generally considered safe and is well-tolerated by most people, some potential health considerations are worth noting. Recent studies have investigated potential links between erythritol consumption and cardiovascular health, though more research is needed to establish causation, and findings have been debated by the scientific community. Some individuals may also experience gastrointestinal discomfort if they consume large amounts of erythritol, though it is typically better tolerated than other sugar alcohols. As with any dietary change, moderation is key and consulting a healthcare professional is recommended.
Conclusion
For those seeking zero-calorie or low-carb sugar alternatives, erythritol is a ubiquitous ingredient in many popular products. Whether it’s acting as a bulking agent for high-intensity sweeteners like stevia and monk fruit in brands like Truvia and Lakanto, or as the foundation for the entire sweetener blend as seen with Swerve, erythritol plays a central role. Its sugar-like taste and texture, combined with its low impact on blood sugar, make it a valuable tool for managing sugar intake. Always check ingredient labels to confirm the presence of erythritol and to choose the product that best fits your dietary needs and preferences.

What to look for when choosing a sweetener with erythritol
When selecting a sweetener that contains erythritol, consider the following points to make an informed choice:
- Review the Full Ingredient List: Some brands contain a blend of sweeteners (e.g., stevia, monk fruit, oligosaccharides) with erythritol as the base. Others sell 100% pure erythritol powder. The blend can affect the flavor profile and how it performs in cooking.
- Understand Brand Variations: A brand like Splenda has multiple product lines. Its yellow packets do not contain erythritol, but certain "Natural" or "Keto" branded products do. Ensure you're buying the correct product for your needs.
- Consider the Form: Erythritol-based sweeteners are available in granular, powdered, and occasionally liquid forms. The form you choose will depend on its intended use, such as for baking, beverages, or dusting desserts.
- Assess Personal Tolerance: While erythritol is generally better tolerated than other sugar alcohols, some people may experience digestive discomfort with high intake. It's wise to start with a smaller quantity to see how your body reacts.
By carefully reading the label and understanding how erythritol is used in different products, consumers can find the right zero-calorie sweetener to suit their taste and dietary requirements.
