Erythritol Ingestion Increases Platelet Reactivity and Thrombosis Potential in Healthy Adults – Arterioscler Thromb Vasc Biol

Study Design and Population: This interventional study evaluated the effects of erythritol versus glucose on platelet reactivity and thrombosis potential in 20 healthy volunteers, with 10 participants in each group. Researchers measured erythritol plasma levels and assessed platelet function through aggregometry and granule marker analysis both before and after ingestion of 30 g of erythritol or glucose.

Main Findings: Erythritol ingestion resulted in a more than 1000-fold increase in plasma erythritol concentration and significantly enhanced stimulus-dependent platelet aggregation and release of serotonin and CXCL4, markers of platelet activation. In contrast, glucose ingestion did not significantly alter platelet reactivity or granule marker release, highlighting erythritol’s unique pro-thrombotic effects.

Implications for Practice: These findings raise concerns regarding the safety of erythritol as a non-nutritive sweetener, particularly its potential to enhance thrombosis risk. The results suggest a need to reevaluate erythritol’s safety status and consider its impact on cardiovascular health in regulatory guidelines.
