Role of Energy Supplements in Enhancing Sports Performance: Current Evidence and Future Perspectives

Abstract

In sports nutrition, energy supplements refer to dietary products such as gels, drinks, bars, or powders developed to deliver rapid or sustained energy, maintain electrolyte balance, and promote recovery, thereby enhancing athletic output and overall performance efficiency. Energy supplements fall under the ergogenic and macronutrient-based category of sports nutrition. They primarily supply carbohydrates, proteins, and fats as energy sources, along with micronutrients (vitamins and minerals) and bioactive compounds such as caffeine, taurine, carnitine, and ginseng that enhance energy metabolism, endurance, and recovery. They provide rapid energy, maintain hydration, delay fatigue, and support metabolic, neuromuscular, and cognitive functions. Despite their benefits, challenges such as inconsistent nutrient content, variable individual responses, and safety concerns highlight the need for quality control and evidence-based use. Supplement combinations such as carbohydrate–protein or carbohydrate–electrolyte mixtures have shown notable benefits in improving power and recovery, particularly in team sports. However, significant research gaps remain, especially regarding female athletes and sport-specific responses. Additionally, some studies report safety concerns and adverse effects, emphasizing the need for careful evaluation and evidence-based use of supplements. Future strategies should focus on personalized supplementation, innovative delivery systems, micronutrient monitoring, and athlete education to optimize performance, reduce fatigue, and ensure long-term health.
