Overview
Erythritol is a low-calorie sugar alcohol used in keto products, protein snacks, tabletop sweeteners, and reduced-sugar beverages. It is popular because it adds sweetness without behaving like table sugar in every nutrition panel.

What It Does in Food
Erythritol is most commonly used as sweetener and bulking aid in packaged food.

Sweetener
Evidence and Regulatory Summary
FDA has cleared erythritol through GRAS notices, and published reviews still treat it as a permitted sweetener. The live debates are about tolerance, metabolic context, and how consumers use it at scale in ultra-processed foods.
Diet Notes
Erythritol is often positioned as keto-friendly because it has a limited glycemic impact, but digestive tolerance varies. For low FODMAP or IBS-aware shoppers, the total dose and the rest of the ingredient list still matter.
Shopper Guidance
Use erythritol as a threshold ingredient. One appearance in a product is not the same as relying on it across several bars, drinks, and desserts in a single day, especially if sugar alcohols already bother your gut.
