Rating (out of 5): 4

Glucose polymers are long chains of glucose molecules (such as maltodextrin and dextrins) that serve as a source of complex carbohydrates. Their use in supporting or treating convalescence—the period of recovery after illness or surgery—is scientifically validated. During convalescence, patients often require increased energy to support tissue repair, immune function, and restoration of lean body mass. Glucose polymers provide a readily digestible, energy-dense carbohydrate source that is less likely to cause gastrointestinal upset compared to simple sugars, making them valuable in oral nutritional supplements and enteral feeding formulas.

Numerous clinical studies have demonstrated that glucose polymer-based enteral and oral supplements help improve nutritional status, energy intake, and recovery outcomes in convalescent patients, especially those who are malnourished, post-surgical, or have increased metabolic demands (e.g., following trauma or infection). Compared to monosaccharides or disaccharides, glucose polymers are less osmotically active, reducing the risk of diarrhea and allowing for higher caloric delivery without gastrointestinal intolerance. This is particularly beneficial in compromised patients with reduced gastrointestinal function.

Guidelines from organizations such as ESPEN (European Society for Clinical Nutrition and Metabolism) and ASPEN (American Society for Parenteral and Enteral Nutrition) recommend the use of carbohydrate-rich, polymer-based nutritional formulas in the management of patients during recovery. Thus, the use of glucose polymers in convalescence is strongly supported by scientific evidence and clinical practice guidelines.
