The term peptide-based is used because the presence of peptides as the main source of protein is the most characteristic feature of Nestlé Peptamen. Its source of protein, carbohydrate and ready-to-absorb fat blend was specially developed for the patients at risk for malabsorption or who have documented GI dysfunction. It is powdered and appropriate for both oral and tube feeding. Nestlé Peptamen's protein, carbohydrate and fat are provided in forms that require minimal GI tract functioning for digestion and absorption.
