The American Society of Parenteral and Enteral Nutrition defines ONS as a manufactured liquid, reconstitutable powder, and/or solid product that contains a combination of carbohydrates, proteins, fats, fiber, vitamins, and minerals intended to supplement a portion of a patient’s nutrition intake.
ONS are designed to be taken orally by patients who are able to eat some normal food on their own but are unable to meet their nutritional requirements. In these patients, ONS are provided as at-will drinks (sip feeds) or solids to supplement regular food intake.
ONS are nutritionally effective in a wide range of diseases or illnesses including acute illnesses (in-hospital and outpatient settings), surgery (pre- and post-operatively), cancer, stroke and gastrointestinal conditions.
There are also disease-specific ONS that are formulated to meet unique nutritional needs of people with certain disease conditions like diabetes and kidney disease and are designed to address unique nutritional requirements imposed by these conditions.
