Overview

• A University of Colorado Boulder study found that erythritol, a common sugar substitute, can elevate oxidative stress and reduce nitric oxide production in brain blood vessel cells.
• Exposure to erythritol levels found in a single energy drink serving caused nearly 100% more free radicals and reduced nitric oxide, which is essential for healthy blood flow.
• These findings reinforce earlier research linking erythritol to increased risks of blood clots, heart attacks, and strokes.
• Experts recommend moderating erythritol intake, particularly for individuals with pre-existing vascular health risks, while long-term clinical trials are called for to assess safety.
• Despite its FDA and NHS approvals as safe, the study challenges erythritol's reputation as a healthier alternative in sugar-free and keto products.
