The Claim

In older adults with Alzheimer's disease, daily supplementation with 20 grams of creatine monohydrate for eight weeks is associated with a small but statistically significant increase in leg muscle cross-sectional area, with rectus femoris increasing from 7.6 to 7.8 cm² and vastus medialis from 10.1 to 10.2 cm².

In plain English

In older adults with Alzheimer's disease, taking 20 grams of creatine monohydrate daily for eight weeks is associated with a small increase in the size of leg muscles, specifically the rectus femoris and vastus medialis.

See the scientific wording

In older adults with Alzheimer's disease, daily supplementation with 20 grams of creatine monohydrate for eight weeks is associated with a small but statistically significant increase in leg muscle cross-sectional area, with rectus femoris increasing from 7.6 to 7.8 cm² and vastus medialis from 10.1 to 10.2 cm², suggesting a potential role in mitigating muscle atrophy in this population.

Why this might work

Creatine pulls water into muscle cells, making them swell, which signals the cells to build more protein and stop breaking down muscle tissue. More creatine also helps make more energy, allowing muscles to work harder and stay bigger.

  1. Study: Eight weeks of creatine monohydrate supplementation is associated with improvements in muscle size in Alzheimer's disease

    In a small study, older adults with Alzheimer's who took 20 grams of creatine daily for eight weeks saw their leg muscles get just a tiny bit bigger, which might help slow muscle loss from the disease.
