What's in Splenda Brand Stevia?
When you buy a box of Splenda brand stevia, you're not just getting pure stevia leaf. You are purchasing a blend designed for a specific taste and texture profile. The sweetness comes from highly purified steviol glycosides, which are natural compounds extracted from the stevia plant leaves. The rest of the product is made up of additional ingredients, such as bulking agents and other sugar substitutes, which vary depending on the product line. For example, Splenda Stevia may contain ingredients like erythritol or maltodextrin to provide bulk and improve the flavor, which is a key difference from unadulterated stevia leaf extract.
Pure Stevia vs. The Splenda Blend
It's important to distinguish between pure stevia and the commercial blends sold under the Splenda brand. While pure stevia leaf extract has a bitter aftertaste for some, companies add other ingredients to commercial products to mask this flavor and create a taste closer to sugar. This is where consumer caution is needed, as the added ingredients can carry their own health considerations, as will be discussed in detail below.
The FDA's Stance on Stevia and Splenda's Ingredients
For the most part, the safety of stevia extracts is well-documented and accepted by regulatory bodies. In the U.S., the FDA has granted high-purity steviol glycoside extracts a 'Generally Recognized as Safe' (GRAS) status, meaning they are considered safe for consumption. This approval does not extend to whole stevia leaves or crude stevia extracts, which have not undergone the same rigorous testing. The safety concern with Splenda's products, therefore, often lies not with the high-purity stevia extract itself, but with the additional ingredients used in their blends.
The Controversial Additive: Erythritol
One such common additive is the sugar alcohol erythritol, which is included in many stevia-based products to add bulk and improve texture. While erythritol has long been considered safe, a recent study from 2023 caused alarm by linking higher blood erythritol levels to an elevated risk of major cardiovascular events like heart attack and stroke. It's important to note that more research is needed to fully understand the long-term effects, especially since the human body naturally produces erythritol. Nevertheless, the study suggests moderation is wise, particularly for those with existing heart conditions.
Potential Side Effects of Splenda Stevia
While high-purity stevia extracts are generally well-tolerated, some individuals may experience side effects, particularly from the added sugar alcohols. These can include mild to moderate digestive issues, as with many low-calorie sweeteners.
- Gastrointestinal Distress: Sugar alcohols like erythritol can draw water into the gut, potentially causing bloating, gas, or diarrhea, especially when consumed in large quantities.
- Blood Sugar Management: Though pure stevia does not raise blood sugar, some stevia blends containing maltodextrin have a minimal caloric impact and could potentially cause a slight rise in blood sugar in sensitive individuals.
- Potential Interactions: In rare cases, stevia may interact with medications for diabetes or high blood pressure, and it is also not advised for people taking lithium.

Is Splenda Brand Stevia Safe: The Conclusion
So, is Splenda brand stevia safe? The short answer is yes, for most people, when consumed in moderation. The high-purity stevia extract itself is considered safe and has been cleared by major health agencies. The primary areas for caution revolve around the specific product formulation. Consumers, especially those with existing health concerns like diabetes or heart issues, should pay close attention to the other ingredients listed on the label, particularly erythritol. For the healthiest approach, it is advisable to limit your intake of any added sweeteners, including Splenda Stevia, and focus on naturally sweet whole foods like fruit whenever possible. The safety data remains strong for the pure stevia component, but a product is only as safe as its weakest ingredient. As always, consulting with a healthcare professional before significantly altering your diet is a wise step.
