The real benefits of creatine (and who it's actually for)

Creatine has a reputation problem. People think it's a steroid, or that it'll make you puffy, or that it's only for bodybuilders. None of that is true.

It's a compound your body already makes and stores in your muscles. You get some from red meat too. Supplementing just tops the tank right up, and a full tank is where the benefits live.

What it actually does

More reps before failure. Creatine helps regenerate ATP, the energy your muscles burn in short, hard efforts. More available energy means an extra rep or two on the big sets. Over months, those extra reps add up to real strength and size.

Faster recovery between sets and sessions. You refill energy quicker, so you can push the next set harder.

A bit more water inside the muscle. This is the "creatine bloat" people worry about, except it's water held inside the muscle cell, not under your skin. It makes muscles look fuller, not softer.

It's not just physical. There's solid research on creatine and cognition, especially when you're sleep-deprived. Handy if you train early or shift-work your way through the week.

Who should take it

Anyone lifting weights, sprinting, or playing stop-start sport. Plant-based eaters often see the biggest jump, because they're starting with less in the tank.

You don't need to "load" it. Loading (20g a day for a week) fills your stores faster, but 3-5g a day gets you to the same place in a few weeks with no stomach upset. Pick whichever suits you.
