Background and Purpose: Recent advances in sports nutrition suggest that dietary supplements can play an important role in enhancing performance, reducing fatigue, and accelerating recovery in football players. The purpose of this study was to synthesize and integrate existing scientific evidence on the performance effects, physiological mechanisms, research limitations, and practical implications of four commonly used supplements—nitrate (beetroot juice), caffeine, creatine, and beta-alanine—in professional football.
Methods: A synthesis research study was conducted based on articles published between 2020 and 2025. Relevant studies were identified through the ISI Web of Science, Scopus, PubMed, and Cochrane Library databases. Following methodological quality assessment, data extraction, and thematic analysis, 41 scientific articles published between 2020 and 2025 were comparatively reviewed.
Results: The findings indicated that nitrate and creatine, when consumed according to appropriate supplementation protocols, showed the strongest supporting evidence for improving anaerobic performance and intermittent high-intensity activities. Caffeine demonstrated robust ergogenic effects; however, its effectiveness was dose-dependent and influenced by substantial inter-individual variability. In contrast, beta-alanine required longer supplementation periods to elicit meaningful physiological and performance-related adaptations.
Conclusion: Overall, evidence-based and targeted use of nutritional supplements can serve as an effective component of preparation, training, and rehabilitation programs in professional football, contributing to enhanced performance and reduced player fatigue
