The Claim
Creatine supplementation combined with resistance training results in a modestly greater hypertrophic effect in younger adults (mean age 23.5 years) compared to older adults (mean age 61.6 years), with a standardized mean difference of 0.17 (95% CrI: −0.45 to 0.09), but the practical significance of this difference is limited due to wide confidence intervals and small overall effect sizes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults who take creatine and do resistance training, younger people experience slightly more muscle growth than older people, but the difference is so small and uncertain that it may not matter in practice.

Creatine supplementation combined with resistance training may have a modestly greater hypertrophic effect in younger adults (mean age 23.5 years) compared to older adults (mean age 61.6 years), with a standardized mean difference of 0.17 (95% CrI: −0.45 to 0.09), but the practical significance of this difference is questionable due to wide confidence intervals and small overall effect sizes.
Creatine lets muscle cells make more energy quickly during hard workouts, pulls water into the cells to signal growth, and helps repair and build muscle fibers by activating special stem cells that add new nuclei to muscle cells.
What the research says
1 studyThe study found that younger people might get a tiny bit more muscle growth from creatine and weights than older people, but the difference is so small and uncertain that it might not matter in real life — which is exactly what the claim says.
