Composition and properties
Glucerna products are formulated with fat, protein, vitamins, minerals, and carbohydrates including CarbSteady, proprietary carbohydrate blend containing sucromalt that is characterized by a reduced glycemic index of approximately 53. Some Glucerna products contain chromium picolinate, and phytosterols. There is evidence that phytosterols may help lower cholesterol, but the efficacy of chromium supplementation has not been fully agreed among experts.
The glycemic index of Glucerna shakes is approximately 31 relative to a value of 100 for pure glucose, while the snack bar has been found to produce less than a third of the glycemic response of a conventional snack bar. A scientific review concluded that diabetic snack bars, such as Glucerna snack bars, can be useful for weight control and for blunting hyperglycemia but are not suitable for treating hypoglycemia.
