Ch. R. R. Alves and colleagues published a study: “Creatine
Supplementation in Fibromyalgia: A Randomized, Double-Blind, Placebo-Controlled
Trial”. Results: „ After the
intervention, the creatine group presented higher muscle phosphorylcreatine
content when compared with the placebo group (+80.3% versus −2.7%; P = 0.04).”
Furthermore, the creatine group presented greater muscle strength in the leg
press and chest press exercises and also isometric strength was greater in the
creatine group than in the placebo group. “However, no general changes were
observed in aerobic conditioning, pain, cognitive function, quality of sleep,
and quality of life. Food intake remained unaltered and no side effects were
reported.“
Body builders use creatine
supplementation to boost muscle growth. So, it isn’t surprising if people, who
haven’t trained due to pain, gain something out of a training and may benefit in muscle strength from this supplementation. But muscle strength isn’t the problem in
fibromyalgia!
Do fibromyalgia patients
need a creatine supplementation? No! The impact on more clinically relevant measures for
fibromyalgia, such as aerobic conditioning, pain, cognitive function, quality
of sleep, and quality of life had been disappointing as these remained
unchanged.
Supplementation of creatine in fibromyalgia patients is a dead end and
might stir false hopes. I recommend to stay away from it.
