Is Allulose Safe?

The FDA has not objected to three generally recognized as safe (GRAS) notifications, GRN 400, GRN 498 and GRN 693, for the use of allulose as a sugar substitute in certain conventional foods and beverages. That is the FDA's regulatory position, not a test result of our own.

Allulose, or D-psicose, is a monosaccharide and an epimer of fructose that the FDA says occurs naturally in small amounts in wheat, in fruits such as raisins and dried figs, and in foods such as molasses, maple syrup and brown sugar. The FDA concluded its caloric contribution is very low, no more than 0.4 calories per gram, because most allulose is excreted intact in the urine and it is poorly fermented in the gut.

On labels, the FDA's October 2020 final guidance says it intends to exercise enforcement discretion so manufacturers can leave allulose out of Total Sugars and Added Sugars and use 0.4 calories per gram when calculating Calories, pending a rulemaking. That followed a draft the FDA announced in the Federal Register of April 18, 2019. Allulose must still be declared in the ingredient statement, the FDA notes, so consumers can tell when it is in a food.
