Erythritol is the only zero-calorie sugar alcohol with a small molecular weight that is easily absorbed by the body. However, only a small amount of erythritol is absorbed into the human colon by microbial fermentation, 80% of the erythritol is consumed by the human body into the bloodstream, but can not be broken down by the body's enzymes and metabolism, can only be discharged from the human body through the urine. Therefore, the metabolism of erythritol in the human body is slow, and can gradually release energy, so that the blood sugar level remains stable.
