Internal Medicine

Erythritol is a sugar alcohol (polyol) commonly used as a low-calorie sweetener. Naturally found in some fruits and fermented foods, it is roughly 70% as sweet as sugar but contains almost no calories and doesn't raise blood sugar or insulin levels, making it popular in keto, diabetic, and sugar-free products.

While generally recognized as safe, some people experience side effects like bloating, gas, or digestive discomfort, and recent research has raised questions about potential cardiovascular effects with high intake. If you've noticed unusual symptoms after consuming erythritol or other sweeteners—or you're simply unsure what's causing how you feel—it's worth getting clarity fast. Take a free, instant, online symptom check to better understand your situation and confidently plan your next steps.
