Creatina melhora a função cognitiva?

A creatina ganhou fama por melhorar a performance física – e, segundo influenciadores, também ajudaria o cérebro.

Foco, memória afiada, prevenção de Alzheimer... Essas são algumas promessas que circulam nas redes em relação ao suplemento.

Mas será que elas se sustentam? A resposta curta: não há comprovação científica desses efeitos cognitivos.

Estudos de boa qualidade sobre o tema ainda são escassos – e os que existem mostram efeito nulo ou incerto.

Segundo o fisiologista Hamilton Roschel (USP) em entrevista à Veja Saúde, não dá para afirmar que a creatina melhora a função cerebral em pessoas saudáveis.

Outras promessas, como ajuda em autismo, crescimento infantil e emagrecimento, também carecem de evidência sólida.

A creatina é bastante estudada e sabe-se que ela traz um benefício em relação à performance física – mas mesmo esse efeito é pequeno. Vale lembrar: não existe suplemento milagroso.

No cérebro, porém, a creatina ainda está no campo da especulação. Cuidado com discursos milagrosos e sem validade científica.
