Clinicians are in need of guidance that will ease the application of medical nutrition therapy. The first treatment choice in medical nutrition therapy is the use of oral nutritional supplements (ONS) after or concomitant with dietary interventions. The pre and post-graduate curriculum for medical nutrition therapy is limited in most regions, worldwide. A report that is short, clear, and having clear-cut recommendations that will guide the primary healthcare professionals in indications, choice, practical application, follow-up, and stopping ONS would facilitate the application and success of medical nutrition therapy. KEPAN is the Clinical Enteral and Parenteral Nutrition Society of Turkey and is an active member of the European Society for Clinical Nutrition and Metabolism (ESPEN). In this study, we present the KEPAN ONS consensus report on optimal ONS use in medical nutrition therapy as outlined by works of academicians experienced in clinical application of ONS (eight working group academicians and 19 expert group academicians). This report provides 22 clear-cut recommendations in a question-answer format. We believe that this report could have a significant impact in the ideal use of ONS in the context of medical nutrition therapy when clinicians manage everyday patients.
