The Rise of Erythritol and Health Concerns
Erythritol, a popular sugar alcohol, has been a staple in the protein powder and low-carb food industries for years. Its appeal lies in its zero-calorie nature, sweet taste, and function as a bulking agent, making it ideal for creating “sugar-free” products. For individuals with diabetes or those following a ketogenic diet, erythritol seemed like a perfect solution, as it does not spike blood sugar or insulin levels.
However, recent scientific findings have cast a shadow of doubt over its safety. A 2023 study published in Nature Medicine, and funded by the NIH, linked higher circulating levels of erythritol to an elevated risk of major adverse cardiovascular events, such as heart attack and stroke, in individuals who were already at high risk. While the study's authors noted that further research is needed, the findings have prompted many to re-evaluate their consumption of products containing this sweetener. Beyond potential cardiovascular risks, some individuals also report gastrointestinal distress, including bloating, cramping, and gas, from consuming high doses of erythritol.
How to Identify Erythritol in Protein Powders
One of the biggest challenges for consumers is that erythritol isn't always prominently displayed on a product's label. It can be listed under 'sugar alcohols' or included in proprietary 'natural sweetener blends,' particularly those containing stevia or monk fruit extract, as it’s often used to enhance their taste and texture. The key to avoidance is a careful, detailed read of the ingredients list. Look for the word 'erythritol' specifically, as well as general 'sugar alcohol' mentions, and be cautious with any ambiguous 'natural flavors' or 'sweetener blends.' Choosing an unflavored, unsweetened protein powder is the most direct way to guarantee the absence of erythritol and other additives.

Making an Informed Decision: What to Look For
When navigating the protein powder market for erythritol-free options, consider the following checklist:
- Read the Full Ingredient List: Don't rely solely on marketing claims like "natural" or "sugar-free." Scrutinize the ingredient list for 'erythritol' or any 'sugar alcohols.'
- Opt for Unflavored Varieties: The safest bet is an unflavored and unsweetened powder. This gives you full control over what goes into your shake and allows for natural flavorings like fruit or spices.
- Investigate Sweetener Blends: If a product contains stevia or monk fruit, research the brand to ensure they don't use erythritol as a bulking agent. Many transparent brands will clearly state their blend is erythritol-free.
- Consider Natural Sweeteners: Powders sweetened with real, but lower-sugar, options like organic cane sugar or coconut sugar are viable alternatives, provided you are mindful of your total sugar intake.
- Seek Third-Party Certification: Look for certifications like USDA Organic or Non-GMO Project Verified, as these often indicate a commitment to cleaner, more natural ingredients. One can also use consumer advocacy resources such as EWG for more information on food products and ingredients.

By carefully checking ingredient labels and understanding the types of sweeteners used, consumers can find products that align with their health and wellness goals.
