Stevia is a natural, zero-calorie sweetener favored as a healthy sugar alternative. While pure Stevia rarely causes loose stools, many Stevia products contain sugar alcohols that can lead to diarrhea and digestive upset. Research shows Stevia mainly supports gut health without negative effects, but individual sensitivities exist. Choosing pure Stevia and moderating intake can help avoid digestive discomfort. Stevia also offers benefits like blood sugar control, weight management, and antioxidant effects for overall wellness.
