DOES IT WORK?
Erythritol is the most gut-friendly sugar alcohol. Unlike sorbitol or maltitol, about 90% is absorbed in the small intestine and excreted unchanged in urine, so it rarely causes digestive issues. Zero calories, zero glycemic impact, and it may even be good for dental health. One 2023 study raised questions about cardiovascular risk at high blood levels, but this is still debated.

Mechanism of Action
Erythritol is a 4-carbon sugar alcohol absorbed in the small intestine via passive diffusion. About 90% enters the bloodstream and is excreted unchanged by the kidneys. It doesn't raise blood glucose or insulin because it's not metabolized. In the oral cavity, it can't be fermented by bacteria, potentially inhibiting dental plaque.
