Creatine supplementation reduces the loss of muscle mass during hormonal shifts.

See the scientific wording

Creatine supplementation helps preserve muscle mass during hormonal shifts

Why this might work

Creatine enters muscle cells and gets converted into a high-energy molecule that quickly replenishes the fuel muscles use to contract. This allows muscles to work harder and longer during physical activity, which puts more stress on the muscle fibers. That stress triggers signals inside the muscle that turn on protein building and turn off protein breakdown, leading to more muscle tissue being kept or built even when hormones drop.

What the research says

3 studies

  1. Study: Creatine monohydrate for lean mass, strength, and bone density in postmenopausal women: a systematic review and meta-analysis

    When postmenopausal women took creatine and did weight training, they gained a little more muscle than those who didn’t take creatine. So yes, creatine can help keep muscle from falling off during hormonal changes like menopause — but only if you also exercise.

  2. 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 strength training kept more muscle than those who only did strength training. Since older adults often lose muscle due to hormonal changes, this suggests creatine helps protect muscle during those changes.

  3. Study: Effect of Creatine Supplementation During Cast-Induced Immobilization on the Preservation of Muscle Mass, Strength, and Endurance

    When people were stuck in a cast and couldn't move their arm, those who took creatine kept more muscle than those who didn't. This suggests creatine might help protect muscle when hormones change and muscles start to shrink.
