Creatine Works — But Only If You Drink Like You Mean It

The hot take that gets me in trouble at coffee shops. Why creatine is the most studied supplement on the planet, and the one rule that decides whether it makes you strong or makes you cramp.

I'm going to say something that always starts an argument at the gym counter: creatine monohydrate is the cleanest, cheapest, most studied performance supplement on the planet. It works. It's been beaten on by sports scientists since the early 1990s. The verdict has not moved.

But here is the part most influencers conveniently skip in the 30-second reel: creatine pulls water into your muscle cells. That is literally how it does its job. It saturates the muscle, hands ATP a backup battery, and lets you squeeze one more rep out of the same lift. Without water, the mechanism does not run. With not enough water, you cramp, you feel puffy, you feel slow, and you blame the supplement.

The riff that runs the engine

Think of creatine like a guitar amp. The amp itself is brilliant gear. But if you do not plug it into power — water, in this case — it is a 40-pound paperweight with a knob on top. The water is not optional. The water is the cable.

My rule for every client on creatine: at minimum, half your body weight in pounds, in ounces of water, every day. A 180-pound lifter? 90 ounces, floor. Hot day, 90-minute squat session, sauna afterward? Add 20 to 30 more.

What the dose actually looks like

Five grams of creatine monohydrate, every single day. Same time every day. No 'loading phase' required — that's a marketing leftover from the 90s. Skip the flavored, color-stuffed creatine blends. The micronized white powder in the unsexy tub is the one that works.

Mix it in your first glass of water of the day. Not coffee. Not a protein shake you might forget to finish. Water — because the same act that gets the creatine into your body also reminds you to start the hydration clock.

Who actually needs it

Anyone training hard three or more days a week. Anyone in a cut who wants to keep the muscle they earned. Anyone over 40 who has watched their lean mass slowly walk out the door. The research on creatine and aging muscle is, frankly, embarrassing for the people still telling you it's a 'bro supplement.'

What it will not do

Creatine will not shred you. Creatine will not replace sleep. Creatine will not turn a half-baked program into a working program. It is the last 5% on top of the first 95%. If the 95% is missing, do not waste your $20.

The pain part

You will gain a few pounds of water weight in the first two weeks. That is the point. The scale will go up before it goes down. If you are not mentally ready for that, you are not ready for the supplement. As I tell every client: you have to go through pain in order to receive pleasure. The scale is one of those pains. Trust the program, drink the water, lift the bar.
