Abstract: Creatine supplementation is one of the most studied and effective methods for athletes. The mechanisms by which creatine exerts its beneficial effects include an increase in anaerobic energy capacity, a decrease in protein breakdown, leading to increased muscle mass and physical performance. Additionally, studies show that creatine supplementation can also be used as a potential complementary clinical treatment, demonstrating efficiency in its therapeutic role in health-related conditions (ROSCHEL, et al. 2021). The aim of this study was to conduct a literature review on the use of creatine supplementation and its benefits for human health. The methodology used consisted of a bibliographic analysis of articles published between 2005 and 2023, with the PubMed database being consulted and the following keywords used: creatine, health, and performance. The results showed that most studies focused on physical performance, highlighting creatine's ability to increase strength and power in athletes, its role in rehabilitation and recovery after physical activity, and injury prevention. Furthermore, creatine plays a fundamental role in cellular metabolism, with recent studies indicating that creatine supplementation has the potential to improve brain function and cognitive processing. Conditions such as diabetes, sarcopenia, osteoporosis, cancer, cardiovascular health, Alzheimer's disease, and depression are also influenced by the amount of creatine present in the body (ROSCHEL, et al. 2021). Several studies highlight the beneficial effects of creatine supplementation at different dosages and time periods. For example, ingesting 5 g/day for 15 days was associated with improvements in cognitive aspects such as attention, memory, and IQ (LING et al. apud ROSCHEL, 2020). Another study demonstrated that 8 g/day for 5 days also resulted in cognitive improvements (WATANABE et al. apud ROSCHEL, 2021). In the context of physical performance, 3 g/day for 12 weeks led to a 2.2% increase in total body mass and a 2.8% increase in lean mass (KERKSICK et al. apud GUALANO, 2010). Additionally, a dose of 0.4 g/day for 6 months was effective in improving various parameters, including recovery, neurophysical, and cognitive functions (SAKELLARIS, G. et al., 2006). Finally, 6 g/day for 5 days resulted in a reduction in glucose concentration (ROCIC et al., 2009), indicating that creatine can have positive effects on both physical performance and cognitive and metabolic health. Based on the studies reviewed, it was concluded that creatine supplementation exerts positive effects on physical performance, while also clearly showing therapeutic potential for some diseases and improvements in cognitive performance. The results of the study suggest that the use of creatine supplementation can contribute to a more comprehensive understanding of human health.
