Rating (out of 5): 4

Glucose polymers, such as maltodextrin, are widely used in sports nutrition to support exercise, especially during prolonged or high-intensity endurance activities. Scientific studies have validated their use as an effective source of rapidly available carbohydrates. Ingesting glucose polymers before, during, or after exercise helps to maintain blood glucose levels, delay fatigue, and replenish glycogen stores.

Unlike simple sugars, glucose polymers provide a steady release of glucose into the bloodstream due to their longer chain structure, which aids in sustained energy delivery without causing rapid spikes and subsequent crashes in blood sugar. Clinical research has shown that carbohydrate solutions containing glucose polymers can improve endurance performance, enhance recovery, and reduce perceived exertion when compared with water or placebo.

Authoritative sports and nutrition guidelines, including those from the American College of Sports Medicine, recommend the use of carbohydrate supplements (including glucose polymers) for athletes engaged in exercise lasting longer than one hour. These recommendations are based on numerous randomized controlled trials and meta-analyses demonstrating benefits for both performance and recovery.

In summary, the use of glucose polymers to support exercise is well-supported by scientific evidence and is a standard practice in sports nutrition.
