Nutrisens long muffins are designed for special medical uses. They are adapted in case of malnutrition, i.e. a pathological condition in which the nutritional intake is insufficient to cover the needs of the organism. The causes of this condition can be multiple and can lead to serious consequences. Malnutrition can also lead to a decrease in the body's defences or muscle wasting. Patients in health and medico-social institutions, as well as the elderly, are particularly at risk. These long muffins have a high protein and energy content. They can be used as a supplement to an already fortified diet or as a single supplement. They provide vitamin D and calcium for bones and protein for muscles. These long muffins are packaged in a pouch and are ready to use, which makes them very easy to use.
