The long-term safety of D-allulose administration in healthy dogs

Abstract

The safety and biological effects of a long-term dose of D-allulose were evaluated in healthy dogs. For 12 weeks, the dogs were administered D-allulose (0.2 g/kg) or placebo daily. Plasma total cholesterol concentrations in the D-allulose group were significantly lower than those in the control group at and after week 2 (P<0.05). D-Allulose administration did not cause clinical signs or changes in hematological and biochemical levels, except for lipids. D-Allulose administration also did not influence body weight. Plasma glucose and insulin concentrations in the glucose tolerance test, performed one day after the termination of D-allulose administration, were not different between groups, suggesting no cumulative effects of D-allulose on glucose metabolism in healthy dogs. In conclusion, long-term administration of D-allulose caused no harmful effects in dogs.
