What Does "Pure Stevia" Really Mean?
Understanding the difference between raw stevia leaf, crude extract, and highly purified steviol glycosides is the first step to finding a pure product. The term "stevia" on a label can be misleading. The FDA has approved only highly purified steviol glycosides, such as Rebaudioside A (Reb A) or Rebaudioside M (Reb M), as safe for consumption. The FDA has not approved whole stevia leaves or crude extracts due to a lack of safety information. High-purity stevia extract must contain a minimum of 95% steviol glycosides.
- Steviol Glycosides: The sweet-tasting compounds extracted from the Stevia rebaudiana plant.
- Rebaudioside A (Reb A): The most common purified glycoside, known for its clean, sugary taste, although some find it has a slight aftertaste.
- Rebaudioside M (Reb M): A newer, more sugar-like tasting glycoside found in smaller quantities, often fermented for commercial use.
Pure stevia extracts are intensely sweet, often hundreds of times sweeter than sugar. This concentration is why many commercial brands add bulk fillers to make the product measure more like sugar.
The Problem with Additives and Blends
Most well-known stevia brands, often found in green packets at the supermarket, are not pure stevia. They are typically blends containing a small amount of Reb A combined with other ingredients. Some common additives include:
- Erythritol: A sugar alcohol used for bulk and to mimic the feel of sugar. While it's generally well-tolerated, some people experience digestive discomfort, gas, or bloating, especially with large amounts.
- Dextrose and Maltodextrin: Corn-based fillers that add bulk and can contribute calories, though often not enough per serving to be listed on labels. This can be misleading for those managing blood sugar, as maltodextrin can have a high glycemic index.
- Natural Flavors: Vague ingredients added to mask the slight licorice or bitter aftertaste that some experience with lower-quality Reb A extracts.
Brands like Truvia and Stevia In The Raw are famous examples of these blends, and reading their ingredient labels reveals that pure stevia is far down the list. For example, Truvia is a blend of erythritol, Reb A, and natural flavors. A product's name can be misleading, so always check the full ingredient list.
How to Find Truly Pure Stevia
Identifying a genuinely pure stevia product requires careful attention to the ingredient list. The goal is to find a product with the fewest ingredients possible, ideally just "stevia extract" or "steviol glycosides."
- Read the Label: The most important step. A pure product will list only one or two ingredients (e.g., purified stevia extract, water for liquid). If you see other names like erythritol, dextrose, or maltodextrin, it's a blend.
- Look for High Purity: Quality manufacturers will often state the steviol glycoside purity level on the packaging, aiming for 95% or higher. Some may also specify the concentration of Reb A or Reb M.
- Consider the Form: Pure stevia is typically available as a highly concentrated white powder (extract) or a liquid drop. The concentrated powder offers the highest purity and best value, as a tiny amount sweetens significantly.
- Trust Reputable Suppliers: Seek out companies that specialize in natural sweeteners or have a strong reputation for ingredient transparency. Avoid mass-market brands that prioritize cost over purity.

Conclusion: Making the Right Choice
Finding a truly pure stevia involves navigating a market full of blends and fillers. By knowing what to look for on an ingredient label—specifically, the absence of added bulk sweeteners like erythritol and dextrose—you can confidently choose a product that fits your health goals. Brands like Pyure, SweetLeaf, NuNaturals, Kaareemi, and steviapura offer high-purity, additive-free options for those seeking the clean sweetness of the stevia plant. Whether you prefer a concentrated powder for baking or liquid drops for beverages, reading the label is the key to ensuring you get exactly what you pay for: pure stevia extract. For further reading, an article from the National Institutes of Health provides an extensive review of the health benefits and properties of Stevia rebaudiana.
Choosing Your Pure Stevia
When selecting a pure stevia product, consider your primary use. For baking, a concentrated powder can work, but remember it lacks the bulk of sugar, so you may need to adjust recipes. For simple sweetening in drinks, liquid drops or the super-concentrated powders are ideal. The taste of different pure stevia extracts can vary slightly based on the glycoside profile (e.g., Reb A vs. Reb M), so personal taste testing may be necessary. By sticking to brands committed to purity, you avoid unnecessary additives and enjoy a cleaner, zero-calorie sweetening experience.
Final Verdict: Which Brand of Stevia is Pure?
Ultimately, determining which brand of stevia is pure depends on your definition of "pure." For a genuinely unadulterated product, seek out brands that list only "stevia extract" or specific steviol glycosides as their ingredients. Brands like Pyure and SweetLeaf offer excellent options. Always prioritize the ingredient list over marketing claims to ensure you are getting a 100% pure product without added fillers or hidden carbs. A little due diligence will ensure your sweetener is as clean as your intentions.
