Splenda is one of the most recognizable and widely used non-nutritive sweeteners on the market, but its composition is often a source of confusion. The brand is built around the artificial compound sucralose, which is intensely sweet and calorie-free. However, the product you buy in packets or in a bag is not pure sucralose. So, to answer the question directly: Yes, Splenda's powdered products, such as its packets and granulated sweetener, contain maltodextrin and dextrose as bulking agents.
Why is Maltodextrin in Splenda?
Pure sucralose is roughly 600 times sweeter than sugar. A single teaspoon of pure sucralose would be excessively sweet, making it challenging for consumers to measure accurately for recipes or beverages. To solve this, manufacturers add bulking agents to dilute the intense sweetness and provide a measure-for-measure consistency similar to table sugar.
This is where maltodextrin and dextrose come in. These carbohydrates act as carriers that add volume and texture to the product. In fact, original granulated Splenda is composed of about 99% maltodextrin and dextrose, with only about 1% sucralose providing the sweetness.
Understanding the Impact of Maltodextrin
For most people using Splenda, the minuscule amount of maltodextrin per serving (typically less than a gram) has a negligible effect on their overall carbohydrate and calorie intake. However, for those with specific health conditions or dietary goals, understanding the implications of maltodextrin is important.
Maltodextrin and Blood Sugar
One of the most significant issues with maltodextrin is its high glycemic index (GI), which often ranges from 85 to 105—even higher than table sugar's GI of 65. This means it can cause a rapid spike in blood sugar levels, which is a key concern for individuals managing diabetes or insulin resistance. While the amount per packet is small, heavy users who consume multiple packets throughout the day should be aware of this cumulative effect.
Maltodextrin and Gut Health
Recent research has also raised concerns about maltodextrin's effect on the gut microbiome, which plays a crucial role in overall health. Some studies suggest that maltodextrin can alter the balance of gut bacteria, potentially suppressing the growth of beneficial probiotics and promoting the growth of certain harmful bacteria, such as E. coli. For individuals with inflammatory bowel conditions, avoiding maltodextrin may be a prudent choice.
Splenda vs. Pure Sucralose: What's the Difference?
It's important to distinguish between the brand name product and the chemical compound it contains. This is often where confusion lies for consumers.
- Splenda (Brand Name): The yellow packets and granulated product sold in grocery stores. These are blends that contain sucralose along with bulking agents like maltodextrin and dextrose.
- Sucralose (Chemical Compound): The intensely sweet, calorie-free ingredient that is the basis for Splenda. Pure sucralose is available to purchase separately, often online, for those who want to avoid added carbs and fillers. It comes in a highly concentrated liquid or powder form.
Alternatives to Splenda Without Maltodextrin
For those seeking a sweetener without maltodextrin, several alternatives are available. Always read the ingredient list, as many powdered versions of these alternatives are also blended with fillers. Look for pure extracts, or liquid and erythritol-based products.
- Pure Stevia Extract: Derived from the stevia plant, pure stevia extract is available in liquid drops or concentrated powder form without fillers. Some blended products, however, do contain maltodextrin or dextrose, so always check the label.
- Pure Monk Fruit Extract: Like stevia, pure monk fruit extract provides intense sweetness with no calories or carbs. Brands like In The Raw offer both maltodextrin and erythritol blends, so scrutinize the label carefully.
- Erythritol: A sugar alcohol that is naturally occurring and provides sweetness with minimal impact on blood sugar. Unlike maltodextrin, erythritol is not rapidly absorbed and is an excellent option for low-carb or keto diets.
- Xylitol: Another sugar alcohol found in plants that is often used as a sugar substitute.
Comparison Table: Sweeteners and Fillers
| Sweetener Product | Sweetening Agent(s) | Bulking Agent(s) | Glycemic Impact | Best For | Considerations |
|---|---|---|---|---|---|
| Splenda (Original Packets) | Sucralose | Maltodextrin, Dextrose | High | Portion control in beverages | Contains small carbs, high GI filler |
| Pure Sucralose (Liquid/Powder) | Sucralose | None | Zero | Precise measurements, avoiding fillers | Very potent, easy to overdo |
| Stevia Extract (Liquid Drops) | Steviol Glycosides | Water, glycerin | Zero | Adding to liquids | Can have a licorice aftertaste |
| Monk Fruit Extract (Pure Powder) | Mogrosides | None | Zero | Concentrated use | Very potent, often blended with erythritol |
| Erythritol | Erythritol (Sugar Alcohol) | None | Zero | Keto baking, measure-for-measure | Can cause digestive issues in large doses |
Making an Informed Decision
For those who only use a packet or two of Splenda per day, the amount of maltodextrin is unlikely to pose a significant health risk. However, for individuals with diabetes, gut sensitivities, or those following a strict low-carb diet, the presence of this high-glycemic filler is a crucial consideration.
Regular consumption of a product with a high-GI bulking agent like maltodextrin can counteract the benefits of using a low-calorie sweetener. If managing blood sugar or gut health is a priority, seeking out pure extracts of sucralose, stevia, or monk fruit—or using sugar alcohols like erythritol—is a more effective strategy.
Ultimately, the choice comes down to reading labels carefully and understanding the difference between the core sweetener and the bulking agents used in commercial products. Making informed decisions about these seemingly small ingredients can have a real impact on your overall health and dietary goals.

Conclusion: Navigating Sweeteners for Optimal Health
In conclusion, the answer to the question, does Splenda have maltodextrin, is a definitive yes for its popular packet and granulated forms. While the product is named after the potent, calorie-free sucralose, the vast majority of its volume consists of fillers like maltodextrin and dextrose. For the casual user, this may not be a concern. However, for individuals carefully monitoring blood glucose or gut health, the high glycemic index and potential impact on gut flora associated with maltodextrin make this a critical distinction. Alternatives like pure stevia, monk fruit, or erythritol are available for those who wish to avoid these fillers entirely. Empowering yourself with the knowledge to read and understand food labels is the first step toward making choices that best align with your nutrition and wellness goals.
