Creatine Supplements May Improve Cognitive Performance After Sleeping Poorly, New Study Shows The scene is all too common: You get a handful of hours of sleep, reach for a cup of coffee every few hours, and then still feel sluggish. But a new study published in Scientific Reports shows that something rather unexpected can perk up your brain power the day following a horrendous night’s sleep. And that something is the popular fitness supplement creatine.
And the result? Overall, these findings are pretty exciting and impressive that a single dose of creatine may be effective at keeping you sharp after really not sleeping much.* Properly dosing creatine The kicker with this study though, is that participants were given a pretty large dose of the supplement. Each participant was given 0.35 grams of creatine per kilogram of body weight. So for a 150-pound individual, that’s about 24 grams. That amount aligns with what is known as a loading dose.
