Enteral Formulas in Nutrition Support Practice: Is There a Better Choice for Your Patient?

Over the past few decades, the number of enteral formulas for use in hospitalized, critically ill, and home enteral patients has dramatically increased. Several enteral nutrition (EN) formula categories exist, which makes it challenging for clinicians to sort through the product claims and find the appropriate formula for the patient. Many formulas are available within each category, some of which may be significantly different from one another. Numerous systematic reviews of existing research and clinical practice guidelines evaluate the use of specialty formulas. This review aims to examine the differences in various enteral formula categories, identify applications in clinical practice, and evaluate the existing evidence and guideline recommendations for use of specific types of enteral formulas.
