Creatine might be more than just a gym staple — it could quietly help your brain too.

The idea that creatine gets into the brain and helps it work better is backed by several studies — people who took it showed small but real improvements in memory and attention, and signs suggest it’s likely reaching brain cells. For depression, some people experienced a meaningful drop in symptoms when taking creatine alongside therapy, though it didn’t help everyone. The claim that it slows Alzheimer’s by 30 percent is too strong — while creatine helped a few small groups perform slightly better on memory tasks and boosted brain energy, no study showed it halts or significantly slows the disease’s progression. The 30 percent figure isn’t supported by the evidence.
