Creatine monohydrate is one of the most studied supplements in sports nutrition history — and also one of the most misunderstood. Here's a clear-headed look at what it actually does.
What Creatine Actually Does
Creatine helps regenerate ATP, your muscles' primary energy source during short, intense bursts of effort — think heavy lifts, sprints, or explosive movements. More available ATP generally means you can push out a few more reps or a bit more power before fatigue sets in.
Common Myths, Addressed
"Creatine causes kidney damage"
In healthy individuals, decades of research have not shown creatine monohydrate to harm kidney function at standard doses (typically 3-5g/day). If you have pre-existing kidney conditions, that's a conversation for your doctor — not a supplement label.
"Creatine is just water weight"
Creatine does pull water into muscle cells, which can show up as a small weight increase early on. But the strength and performance gains behind that are well documented — it's not purely cosmetic.
"You need a loading phase"
A loading phase (higher doses for the first week) saturates muscles faster, but it's not required. A steady 3-5g daily gets you to the same saturation point within about three to four weeks.
How to Take It
- 3-5g per day, any time of day — consistency matters more than timing
- Mixes easily into water, juice, or your protein shake
- Best taken daily, including rest days, since it's about muscle saturation over time, not a pre-workout spike
Who Should Consider It
Anyone doing resistance training, sprinting, or explosive sports stands to benefit. It's one of the few supplements with genuinely strong, consistent research behind it — which is why it remains a staple two decades on.
