Creatine raises brain energy levels and slows Alzheimer's cognitive decline by 30% | Hacker News

A small creatine study suggested higher brain energy and a possible slowing of cognitive decline in Alzheimer's.

Hacker News commenters emphasized the study's tiny sample, high dose, and early-stage nature.

Because creatine is cheap and widely used, even a modest benefit could matter for aging and dementia care.

Still, the evidence is preliminary and needs much larger, better-controlled trials before any treatment conclusions.
