The Claim
Creatine supplementation combined with resistance training for 32 weeks or less in adults aged 50 and older is associated with a moderate improvement in lower limb strength and lean tissue mass.
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 aged 50 and older, taking creatine while doing resistance training for 32 weeks or less is linked to moderate increases in lower limb strength and lean tissue mass.
See the scientific wording
Creatine supplementation combined with resistance training for 32 weeks or less in adults aged 50 and older is associated with a moderate improvement in lower limb strength and lean tissue mass, but the overall certainty of this evidence is low to moderate due to high attrition, unclear randomization, and small sample sizes in the included trials.
Creatine fills muscle cells with more energy molecules, allowing stronger and longer muscle contractions during exercise. This lets the person lift heavier or do more reps, which pulls harder on the muscles. The increased pull triggers the muscle to build more protein and grow larger, making the legs stronger and adding lean mass.
What the research says
1 studyThis study found that older adults who took creatine and did leg exercises for up to 8 months got stronger legs and gained a bit more muscle than those who only exercised. But the studies weren’t huge or perfect, so we can’t be super sure — which matches what the claim says.
