Creatine: The One Supplement Worth the Money
The most researched supplement in sports nutrition — what it does, what it doesn't, and how to use it.
Why creatine is different
Creatine monohydrate has more human research behind it than any other performance supplement, and the findings are consistent: modest improvements in strength, power and training volume, plus a small increase in lean mass. It is also cheap, which is why almost nobody markets it aggressively — there's no margin in it.
What it actually does
It increases the availability of phosphocreatine in muscle, which helps regenerate energy during short, intense efforts. Practically: an extra rep or two on heavy sets, slightly faster recovery between sets. Over months of training, more accumulated volume, which produces more muscle. It doesn't work by magic; it works by letting you train slightly harder.
Dosing and timing, plainly
Around 3-5g daily. It works by saturating muscle stores, which means consistency matters and timing doesn't — take it whenever you'll remember. Loading phases speed saturation up by a couple of weeks but aren't necessary. Monohydrate is the researched form; the expensive alternatives have no advantage.
The water weight question
Creatine draws water into muscle cells, which typically shows up as one to three pounds on the scale in the first weeks. That's intracellular water, not fat and not bloating. It's also why people mistakenly think creatine "stopped working" when the initial scale jump ends.
Side effects and the kidney myth
In healthy people, long-term studies have not shown kidney harm. The persistent myth comes from creatine raising creatinine, a marker used in kidney tests — a measurement artifact, not damage. If you have existing kidney disease, ask your physician. Some people get mild stomach upset at higher single doses; splitting the dose fixes it.
Most people can execute this alone. The ones who stall usually need someone auditing the details — that's what coaching is for.
Who benefits most
Anyone doing resistance training. Interest has widened well beyond bodybuilding into general strength and healthy aging, and the research on older adults combining creatine with resistance training is genuinely encouraging. Vegetarians often see larger effects, since dietary creatine comes mostly from meat.
How to Apply This
Information only becomes useful when it changes what you do. Pick the single change from this page most relevant to your current situation and run it for four weeks before judging it. Changing several variables at once means you learn nothing about which one worked — and most people quit before any of them had time to show an effect.
What to Track
Track the outcome you actually care about, measured the same way each time. Bodyweight as a weekly average rather than a daily reading. Strength as the load and reps you completed, written down. Energy and sleep as a simple one-to-ten note. Numbers you record are the only ones you can act on later, and memory is a far worse record than most people believe.
Common Reasons It Doesn’t Work
Three explanations cover almost every stall. The change was never applied consistently enough to matter. It was applied consistently but not long enough to show. Or something else in the picture — sleep, total food intake, training volume, life stress — was the actual limiting factor and went unaddressed. Before adding anything new, check those three honestly.
When to Get Individual Advice
General information is a starting point, not a plan. If you have an existing medical condition, take prescription medication, are pregnant or nursing, or have symptoms that concern you, speak with a qualified professional who can assess your specific situation. Nothing on this page is medical or individual nutrition advice.
Common Questions
Do I need to cycle creatine?
No. Continuous daily use is well studied and there's no evidence cycling helps.
Does creatine cause hair loss?
One small study raised the question decades ago; it has not been replicated. There's no good evidence for the claim.
Should women take creatine?
The mechanism isn't sex-specific and the research supports the same use.
