New Study Raises Alarm: Erythritol Linked to Increased Blood Clot Risk
Recent research has brought to light some concerning findings about erythritol, a widely used artificial sweetener. The study, published on August 8 in Arteriosclerosis, Thrombosis, and Vascular Biology, suggests that erythritol might increase the risk of blood clot formation. This revelation has significant implications for consumers who frequently use this sugar substitute, commonly found in low-calorie and sugar-free products.

Study Overview
The Cleveland Clinic research examined the effects of erythritol on blood platelets, which are vital for blood clotting. In the study, 20 healthy volunteers were divided into two groups. After fasting overnight, one group consumed a drink containing 30 grams of erythritol, while the other group consumed a drink with 30 grams of glucose. Blood samples were collected before consumption and 30 minutes afterward. The results showed a dramatic increase in erythritol levels in the blood, over 1000 times higher than initial levels. Participants who ingested erythritol exhibited significant platelet aggregation, a process where platelets clump together, which can increase the risk of clot formation. Notably, glucose did not induce these effects, underscoring erythritol’s unique impact on blood platelets.
Implications for Health
Erythritol is frequently used in a range of diet- and sugar-free products, including sugar-free gum, energy bars, diet sodas, and protein shakes. It is often combined with other sweeteners, like stevia or monk fruit, to provide bulk and sweetness without the calories associated with sugar. Despite being classified as a natural sweetener and being found in small amounts in fruits and vegetables, erythritol is produced commercially through fermentation. This production method results in quantities that are far higher than those found in natural sources.
The study’s findings are particularly concerning because increased platelet activity can lead to the formation of blood clots. Blood clots have the potential to travel to various parts of the body, causing serious health problems such as heart attacks, strokes, or pulmonary embolisms. The potential for erythritol to elevate blood clot risks aligns with previous research linking the sweetener to a higher incidence of cardiovascular events.
Expert Opinions and Industry Reactions
While the Calorie Control Council (CCC), which represents the low- and reduced-calorie food and beverage industry, has labeled the study’s findings as “misleading,” this new research adds to the growing body of evidence questioning erythritol’s safety. The CCC maintains that erythritol has been endorsed as safe by global health authorities for over 30 years. However, the study’s results suggest that there may be more to understand about its long-term health effects.
Experts like Thomas M. Holland, MD, from the RUSH Institute for Healthy Aging, and Kiran Campbell, RDN, emphasize the need for caution. Dr. Holland notes that while erythritol’s GRAS (Generally Recognized As Safe) status is based on current knowledge, it may not fully address potential long-term risks. Campbell supports this view, suggesting that consumers, especially those with existing health conditions such as cardiovascular disease, should avoid erythritol until more comprehensive research is available.
Alternatives to Erythritol
For those looking to reduce their intake of artificial sweeteners, several natural alternatives could be considered. These include:
- Pure Honey: is a natural sweetener with potential health benefits, though it should be consumed in moderation.
- Pure Maple Syrup: Offers a distinct flavor and some minerals, making it a popular alternative to artificial sweeteners.
- Dates are a nutrient-dense sweetener that provides fiber and other beneficial compounds.
- Coconut sugar is a less processed sugar with a lower glycemic index compared to regular sugar.
- 100% Stevia Extract: A zero-calorie sweetener derived from the leaves of the stevia plant.
- 100% Monk Fruit Extract: Another calorie-free sweetener made from monk fruit.
While natural sweeteners can be a safer alternative to artificial options like erythritol, they should still be used in moderation to avoid potential long-term negative effects, such as metabolic disorders.

Conclusion
The latest research from the Cleveland Clinic highlights significant concerns regarding the safety of erythritol. A 30-gram serving of this popular artificial sweetener may substantially increase the risk of blood clot formation, which could have serious health implications. Despite erythritol’s status as GRAS and its widespread use, the study underscores the importance of ongoing research and cautious consumption, especially for individuals with cardiovascular conditions.
As evidence against erythritol and similar artificial sweeteners continues to accumulate, it is prudent for consumers to consider natural sweeteners and maintain a balanced approach to their diet. Staying informed about potential health risks and making educated choices can help individuals manage their health more effectively and reduce the risk of adverse outcomes associated with artificial sweeteners.
