Introdução: A creatina, composto naturalmente presente no corpo e adquirido também através da dieta, desempenha um papel na ressíntese de trifosfato de adenosina (ATP) durante atividades físicas intensas de curta duração. A recomendação da Sociedade Internacional de Nutrição Esportiva (ISSN) envolve suplementação diária de 3 a 5 g para maximizar os estoques musculares de creatina, essenciais para suportar a demanda energética durante exercícios repetidos de alta intensidade. Estudos indicam que a suplementação crônica de creatina, combinada com treinamento de resistência, resulta em melhorias substanciais na força muscular e no aumento da massa corporal magra, beneficiando o desempenho esportivo. Assim, compreender os mecanismos pelos quais a creatina influencia a performance é fundamental para orientar sua utilização de maneira eficaz, garantindo benefícios aos athletes. Objetivo: Evidenciar a influência da suplementação de creatina no desempenho de atletas na prática de exercícios físicos, independente da intensidade. Métodos: Estudo de revisão integrativa da literatura nas bases de dados Pubmed e SCIELO, com os descritores “creatine supplementation in sports” e “creatine supplementation”. Foram selecionados 17 artigos publicados a partir de 2004. Resultados: A creatina, como suplemento, é capaz de melhorar a qualidade e intensidade do exercício físico, principalmente através do estímulo à hipertrofia muscular, minimização do dano muscular e regeneração mais rápida do ATP. Conclusão: A suplementação da creatina monohidratada demonstrou ter benefícios ergogênicos relacionados com aumento de força muscular, ganho de massa magra e ação antioxidante, representando vantagem na preparação física e no rendimento esportivo, proporcionando suporte para superar metas atléticas.
