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.

In plain English

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.

Why this might work

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.

  1. Study: The impact of creatine supplementation associated with resistance training on muscular strength and lean tissue mass in the aged: a systematic review and meta-analysis

    This 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.
