The Healthiest Stevia Is Pure and Unblended
The quest for the healthiest stevia begins with understanding the difference between a pure stevia extract and a blended product. When a consumer buys a product labeled "stevia," they are often not purchasing pure stevia leaf extract. Instead, most products found on supermarket shelves are blends containing a small amount of the highly concentrated stevia extract, with the majority of the volume made up of a bulking agent. Historically, these fillers were simply used to make the product easier to measure, since stevia is 200–400 times sweeter than sugar. However, recent health concerns over popular bulking agents have made choosing a pure, unblended option the most prudent health choice.
Steviol Glycosides: The FDA-Approved Component
The U.S. Food and Drug Administration (FDA) has given highly purified steviol glycosides a "Generally Recognized as Safe" (GRAS) status for use in food. This is the key. The GRAS designation applies to purified extracts that are at least 95% steviol glycosides. It is important to note that the FDA has not approved whole stevia leaves or crude stevia extracts, citing inadequate safety data. Therefore, the healthiest products will contain only the pure, refined extract, not ground-up leaves or crude preparations.
The Erythritol and Filler Problem
Many conventional stevia products use fillers like dextrose, maltodextrin, and erythritol to add bulk and counter stevia's slight aftertaste. A significant controversy arose in 2023 when a study published in Nature Medicine suggested that high levels of erythritol could be linked to an increased risk of heart attack and stroke, particularly in individuals already at risk for cardiovascular disease. The study highlighted that many products, including some marketed to diabetic and keto consumers, contain high amounts of erythritol, potentially increasing blood levels thousands of times beyond normal. For this reason, avoiding blends with erythritol is a primary consideration for the healthiest option.
Top Contenders for the Healthiest Stevia Brands
For those seeking the purest and healthiest stevia options, a few brands stand out for their commitment to minimal processing and pure ingredients. These brands offer products that prioritize steviol glycosides without relying on potentially controversial fillers.
- NOW Foods BetterStevia: This brand offers a clear, liquid, alcohol-free stevia that typically contains only stevia extract and glycerin. This approach provides a simple, clean ingredient list, avoiding many common fillers. They also offer organic versions. The liquid format means no bulking agents are needed for volume.
- NuNaturals Liquid Stevia: Similar to NOW Foods, NuNaturals provides an alcohol-free liquid stevia with a straightforward ingredient profile: stevia extract and water. This makes it an excellent choice for those seeking absolute simplicity and purity in their sweetener.
- SweetLeaf SteviaClear: SweetLeaf, one of the original stevia companies, offers liquid stevia products with pure stevia extract and purified water. They have a variety of products, and their focus on the extract without artificial sweeteners is a key differentiator.
- Pyure Organic Stevia Blend: While it is a blend, Pyure is committed to using USDA Organic certified ingredients. However, it's crucial to check the specific product's ingredient list, as some may contain organic erythritol, which, while derived from organic sources, is still the same polyol with the associated cardiovascular concerns. Pyure does offer pure extract options as well.
- Stevia In The Raw Organic: It is important to distinguish between Stevia In The Raw's conventional packets and their organic variety. The conventional version contains dextrose, a common filler. The organic packets and bulk options, however, are often formulated to be free of erythritol and other unnecessary additives, making them a healthier choice from this widely available brand.

Conclusion: Making Your Choice for Healthiest Stevia
Choosing the healthiest stevia is less about selecting a popular brand and more about becoming a savvy label-reader. The primary takeaway is to seek out products made with pure, high-purity steviol glycoside extract and to actively avoid products that use controversial bulking agents, particularly erythritol. While stevia has shown promise for managing blood sugar and reducing calorie intake, the overall health profile of many stevia-based sweeteners is significantly altered by the fillers included. Liquid drops with minimal ingredients are often the safest and cleanest option. As with any dietary choice, moderation is key, and it's always best to consult with a healthcare provider, especially if you have a pre-existing medical condition.

Note: The FDA only approves highly purified stevia extracts. Whole leaf stevia is not approved for use in food additives. This guide focuses on the safest, FDA-approved forms of the sweetener.
Practical Shopping Tips
- Read the Ingredient List: Look for products with "steviol glycosides" or "stevia extract" as the only ingredients, plus water for liquid versions. Avoid brands where erythritol is the first ingredient listed.
- Opt for Liquids: Liquid stevia drops often require fewer additives for volume, making them a purer choice.
- Choose Organic: An organic certification can provide assurance that ingredients are sourced from organic farming and processed according to specific standards.
- Buy from Reputable Brands: Brands like NOW Foods and NuNaturals have built reputations for offering clean, pure products. While other brands are available, always scrutinize the label.
- Use Moderation: Even the healthiest sweeteners should be consumed in moderation as part of a balanced diet. Using less of any sweetener is the best long-term strategy for promoting overall health and a lower dependency on intense sweetness.
How to Find the Purest Stevia
Locating the purest stevia can sometimes feel like a treasure hunt due to the prevalence of blended products. Your best bet is to look for liquid drops or packets explicitly labeled "100% Stevia Extract." If a product is powdered and comes in a 1:1 sugar replacement ratio, it almost certainly contains a bulking agent. Reputable health food stores and online retailers often carry brands known for their ingredient transparency. When in doubt, a quick check of the brand's website will usually reveal their ingredient sourcing and philosophy. Always read the fine print, as marketing terms like "natural" can be misleading.
