| Intact Enteral Formulas
Intact formulas, also called polymeric formulas, contain unaltered molecules of proteins, carbohydrates, and fats. They are best for people who can digest and absorb nutrients without difficulty.
Polymeric formulas are available as standard formulations containing protein isolate with one or more sources of carbohydrate and fat; or as blenderized whole food formulations. Blenderized formulas, which are used infrequently, are more likely to clog feeding tubes since they have a high viscosity. There is a greater risk of food-borne illness with blenderized formulas.
