What Are Some of the Side Effects of Erythritol?


Potential side effects of consuming more than 80 grams of erythritol per day include diarrhea, bloating and stomach upset, according to About.com. Some individuals may experience these side effects as well as headache when consuming erythritol in smaller amounts.

While other sugar alcohols such as sorbitol and xylitol are known to cause digestive upset and diarrhea, erythritol is designed to be less likely to cause these symptoms when consumed in small amounts, according to About.com. This is because it is a smaller molecule that is easily absorbed and excreted through the urine. However, side effects have still been reported after individuals have consumed food or drinks containing erythritol. Since 1997, the sugar alcohol has been generally recognized as safe in the United States, and it is also approved in Japan, Australia and New Zealand as of 2015.

In the United States, erythritol is labeled as having 95 percent fewer calories than sugar, and it does not affect insulin or blood sugar levels, as stated by About.com. Erythritol doesn't contribute to tooth decay as oral bacteria cannot metabolize it. This sugar alcohol is approximately 70 percent as sweet as sugar with a cooling effect on the mouth. It is made by mixing plant sugar with water and fermenting it. The resulting erythritol is filtered before letting it crystallize and dry.
