What foods and drinks contain erythritol?

Erythritol is a low-calorie sugar substitute widely used in sugar-free foods, beverages, and keto-friendly products. While generally recognized as safe, some people may experience allergic reactions or intolerance symptoms after consuming it. Reactions can range from mild skin irritation and hives to digestive discomfort, and in rare cases, more serious responses.

A free, instant, online symptom check can help you quickly identify possible causes, assess urgency, and guide your next steps. Taking a few minutes now could save you time, worry, and unnecessary discomfort later.
