Erythritol is generally well-tolerated compared to some other sugar alcohols, but it can cause bloating, gas, or a laxative effect when consumed in excess, as noted in the product information. This is because sugar alcohols are not fully absorbed in the small intestine. The likelihood and severity depend entirely on your personal sensitivity and the amount consumed in one sitting.
To avoid discomfort, start by introducing a small amount into your diet—for example, use half a serving in your coffee or tea. Pay attention to how your body reacts over the next few hours. If you tolerate it well, you can gradually increase the amount. It's also advisable not to consume large quantities in one go, especially if you plan to use it in baking where a single portion might contain several servings. If you have a known sensitivity to sugar alcohols or conditions like irritable bowel syndrome (IBS), you may want to be particularly cautious or choose a different sweetener option.
