Tens of millions of people take creatine every day for their muscles. A comprehensive review and a landmark clinical trial published in 2025 and 2026 have now documented what the same supplement is quietly doing to their brains. Creatine crosses the blood-brain barrier, raises phosphocreatine levels in neurons, and provides the ATP buffer that keeps cognitive performance from hitting an energy ceiling during demanding mental work. In early Alzheimer's patients, it slowed cognitive decline by approximately 30% versus placebo in a controlled trial. In healthy adults under sleep deprivation, a single dose measurably improved cognitive performance. In depression patients, adding it to cognitive behavioral therapy significantly improved outcomes beyond therapy alone. None of this is mentioned on the label.
I’ve never been able to taste it and searching reveals that pure creatine monohydrate is most likely tasteless. However, some people describe it as slightly sour. However, my experience and that of most people that I’m seeing online report it as being easily masked by coffee, tea, or protein shakes.
Also, I think you meant confidently. I only mention it because it seems like the details matter to you.
