During the 38–40 weeks of a championship, a professional football player is confronted with numerous high-intensity training sessions with high physical and mental stress. This situation requires constant adaptation to the training cycles and match schedule. Performance can be quantified by biochemical biomarkers and physiological, morphological and physical parameters. In this study, a specific supplement was developed to improve post-training recovery using components developed to improve the antioxidant, anti- inflammatory and immunological profile. The study was conducted during 4 weeks of competition in an Italian first division football team comprising 28 professional players. Two groups were established, one taking the product (n = 15) and the other taking a placebo (n = 13). Before and after the intervention, biochemical analyses and laboratory tests (dual-energy X-ray absorptiometry) were conducted to monitor changes. The training sessions were controlled with a GPS to monitor the physical load. After the intervention, an improvement in parameters related to iron metabolism was observed. No significant improvements associated with the intervention could be established in body composition values or biomarkers related to oxidative stress or inflammation.
