The results were concerning: higher levels of erythritol in the bloodstream were strongly associated with an increased risk of clot formation. This, in turn, elevated the likelihood of major adverse cardiac events (MACE) like heart attacks and strokes. Further, laboratory experiments revealed that erythritol could accelerate platelet aggregation—the process by which blood cells stick together to form clots—thus explaining the biological mechanism behind the findings.
Key Findings:
Increased Platelet Activity: The study showed that erythritol promotes platelet aggregation, making it easier for blood clots to form. While clotting is a normal bodily process crucial for stopping bleeding, excessive clotting can obstruct blood flow in critical areas, like the heart and brain, leading to potentially life-threatening conditions.
Elevated Cardiovascular Risk: Participants with high blood erythritol levels were at significantly higher risk of experiencing heart attacks or strokes, especially if they already had underlying cardiovascular conditions. The risk was particularly pronounced among those with preexisting conditions like diabetes, hypertension, and obesity, all of whom are more likely to consume sugar substitutes in efforts to manage their health.
Rapid and Sustained Blood Levels of Erythritol: When volunteers were given beverages containing erythritol, their blood levels of the sweetener increased dramatically and remained elevated for several hours, suggesting that regular consumption could lead to a prolonged state of heightened cardiovascular risk.
Implications for Consumers
These findings raise critical questions about the safety of erythritol, especially for people who are already at risk for cardiovascular disease. The study authors emphasized that while erythritol has long been considered safe due to its low-calorie profile and minimal impact on blood sugar, its effects on cardiovascular health have not been sufficiently examined until now.
For consumers, especially those with a history of heart disease or other cardiovascular risk factors, this study calls for a reevaluation of erythritol’s role in their diet. As it is commonly found in products marketed as “healthier” alternatives to sugar, many individuals may be unknowingly increasing their risk of clotting-related complications.
The Broader Context: Sweeteners and Health
Artificial sweeteners have long been promoted as healthier alternatives to sugar, particularly for individuals with diabetes or those seeking weight loss. Erythritol, in particular, has been favored due to its minimal caloric content and low glycemic index, which means it does not spike blood sugar levels as dramatically as sugar does. However, the assumption that “zero-calorie” automatically means “safe” is now being challenged.
This new research on erythritol adds to a growing body of evidence that certain sugar substitutes may have unintended health consequences. Other studies have linked some artificial sweeteners to alterations in gut microbiota, metabolic dysfunction, and even an increased risk of certain types of cancer. While erythritol is not metabolized in the same way as other sweeteners, its newly discovered effect on blood clotting marks a significant departure from previous safety assumptions.
What’s Next?
The study has prompted calls for further research to understand the full extent of erythritol’s impact on human health, particularly its long-term effects on cardiovascular outcomes. Experts stress that while this study provides strong evidence of a link between erythritol and clotting, more research is needed to confirm these findings in larger and more diverse populations.
Regulatory agencies like the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) may also need to revisit their guidelines on the use of erythritol in food products. Currently, erythritol is classified as “generally recognized as safe” (GRAS) by the FDA, meaning it can be added to foods without extensive pre-market testing. This new evidence could prompt a reassessment of this status, especially if further studies corroborate these findings.
Practical Takeaways for Consumers
For now, what should consumers do? While the study’s results are concerning, it’s important not to panic or make drastic dietary changes without consulting a healthcare professional. Here are some practical steps to consider:
Monitor Your Intake of Erythritol: Check food labels to see if erythritol is a primary ingredient in your diet. Products like sugar-free gum, low-calorie drinks, keto snacks, and certain protein bars often contain erythritol. Reducing consumption of these products may help mitigate potential risks.
Consider Other Sweetener Alternatives: There are many other sugar substitutes on the market, including stevia, monk fruit, and allulose. Each has its own profile of benefits and risks, so it’s worth researching and discussing with your healthcare provider to find the best option for your needs.
Talk to Your Doctor: If you have a history of cardiovascular disease or other risk factors like diabetes, it’s a good idea to discuss these findings with your doctor. They can provide personalized advice based on your overall health profile.

The new study linking erythritol to blood clotting and cardiovascular events highlights the complex nature of artificial sweeteners and their impact on health. While erythritol may be a popular choice due to its sugar-like taste and minimal calorie count, the potential risks for those with heart disease or other risk factors cannot be ignored. As research continues to evolve, consumers should stay informed and make dietary choices that prioritize both taste and long-term health.
