The Claim

Twelve months of creatine supplementation at 0.1 g/kg/day combined with supervised whole-body resistance training in older males aged 49–69 does not result in significantly greater improvements in bone mineral density, bone geometric properties, muscle thickness, lean tissue mass, or muscle strength compared to placebo.

Cause and effect

In plain English

In men aged 49 to 69, taking creatine daily for a year along with supervised strength training does not lead to greater improvements in bone density, muscle size, lean mass, or strength than strength training alone with a placebo.

See the scientific wording

Twelve months of creatine supplementation (0.1 g/kg/day) combined with supervised whole-body resistance training in older males aged 49–69 does not result in significantly greater improvements in bone mineral density, bone geometric properties, muscle thickness, lean tissue mass, or muscle strength compared to placebo, suggesting creatine adds no meaningful benefit beyond resistance training alone in this population.

Why this might work

When older men lift weights, their muscles and bones respond by growing stronger and denser. Adding creatine doesn't make this happen any more because their muscle cells are already full of energy molecules, and the signals that tell cells to build more muscle or bone don't get any stronger with extra creatine.

  1. Study: Effect of 12 months of creatine supplementation and whole-body resistance training on measures of bone, muscle and strength in older males

    In this study, older men took creatine or a sugar pill while doing the same strength workouts for a year. At the end, both groups got just as strong and built the same amount of muscle and bone — so creatine didn’t help any more than the placebo.
