All Peptamen® products are nutritionally complete, "peptide-based" tube feeding formulas thoughtfully made to deliver superior tolerance and absorption. Peptamen® tube-feeding formulas are recommended for individuals who: Cannot tolerate formulas with intact or whole protein, also known as standard formulas Have digestive tract impairment, which may lead to diarrhea, vomiting or discomfort associated with tube feeding May have problems digesting or absorbing protein or fat. Peptamen® was created over 37 years ago from a simple concept: people with conditions that compromise their GI function need better, specialized nutrition in order to grow, thrive and enjoy life to their fullest potential. Peptamen® formulas were therefore designed as unique, nutritionally complete, peptide-based liquid diets presented in an easily absorbable form. The launch of our “state of the art” blend of protein, carbohydrate, fat, vitamins and minerals and subsequent product improvement make Peptamen® formulas suitable for a long list of GI impairments and nutritional applications.
