Is Erythritol banned?
Erythritol is permitted by the US FDA. Several countries restrict, warning-label, or have reviewed it for safety concerns. The US has more lenient additive rules than the EU, UK, Canada, and Japan, which is why this ingredient remains widely used here.
Why Erythritol is flagged
A 2023 observational study published in Nature Medicine (Hazen et al., Cleveland Clinic) found that elevated blood erythritol levels were associated with increased risk of major adverse cardiovascular events (MACE), including heart attack and stroke. Additionally, erythritol was found to enhance platelet aggregation in vitro. This study was widely reported and has generated significant scientific debate; critics note that it was observational (not causational), and that the study population had pre-existing cardiovascular risk factors. Regulatory agencies have not changed their approval status. The long-term cardiovascular implications require further research.
