The Cochrane researchers reviewed 12 studies that included 266 people with different types of muscular dystrophy. People in the studies who took creatine supplements used them for three weeks to six months.
In muscular dystrophies, the proteins that make up the muscles themselves are either missing or damaged. In a related group of disorders called metabolic myopathies, the chemicals that help muscles operate go awry.
Although creatine seemed to help many patients with muscular dystrophies, those with metabolic myopathies gained no more muscle strength or lean body mass than patients who did not use the supplement.
The reason for the contrasting results — creatine’s “fairly consistent” effects in muscular dystrophy and lack of effectiveness in metabolic diseases — is “not entirely clear,” Kley said, calling for more research on treatment for metabolic disorders.
The review was supported by the Neuromuscular Center Ruhrgebiet/Kliniken Bergmannsheil, at Ruhr-University Bochum and the Hamilton Health Sciences Corporation, in Canada. Kley and colleagues have each participated in trials of creatine treatment for muscle disorders, although none of the studies was sponsored by a maker of creatine.
