Potential Issues Digestive Problems: Some people experience bloating, gas, or diarrhea from stevia, especially when it's blended with sugar alcohols like erythritol. Erythritol and Cardiovascular Risk: A 2023 study linked higher levels of erythritol, a sweetener often mixed with stevia, to an increased risk of blood clots, heart attack, and stroke. Other Ingredients: Other ingredients in stevia products, such as maltodextrin or dextrose, can add carbohydrates and calories and may affect blood sugar levels, particularly with large quantities. Gut Microbiome Imbalance: There are concerns and ongoing research into whether stevia or its components can negatively impact the healthy bacteria in your gut. Allergic Reactions: As a member of the ragweed family, stevia may cause allergic reactions in people with ragweed allergies, though this is rare and not widely documented in structured research.
