Erythritol is a low-calorie clean label sweetener of sugar alcohol derived from corn via fermentation. It does not affect blood sugar. It’s often better tolerated than other sugar alcohols. Erythritol may suppress the growth of bacteria in the mouth. The WHO/FAO Joint Expert Committee on Food Additives (JECFA) reviewed the safety of erythritol in 1999 and established an ADI of “not specified,” the highest safety category possible.*
