Creatine: a simple, research-backed guide
Creatine is one of the most studied supplements in existence — and one of the few where the research is both extensive and clear. Here's what you need to know, without the mystery.
What creatine is
Creatine is a compound your body makes itself, and that you also get from meat and fish. It's stored in your muscles (and, in smaller amounts, your brain), where it acts as a fast energy buffer for cells working hard over short bursts.
A creatine monohydrate supplement is simply a way to top those stores up beyond what diet alone provides.
What the research actually shows
The best-documented effect is about training. It's so well established that it's one of the few health claims EU authorities have approved for creatine:
Creatine increases physical performance in successive bursts of short-term, high-intensity exercise. The beneficial effect is obtained with a daily intake of 3 g.
In practice: for strength work, intervals and anything demanding short, hard efforts, creatine is one of the safest helpers you can add.
Who it's for
- People who train with strength or high intensity.
- Vegetarians and vegans, who naturally have lower creatine stores because they get little from food.
- Older adults — for adults over 55, EU rules also recognise that daily creatine can enhance the effect of resistance training on muscle strength.
How to use it
The simple approach works: 3 grams daily, mixed with water. You don't need a "loading phase" to benefit — steady daily intake fills your stores over a few weeks (see how much creatine).
Is it safe?
Creatine monohydrate is among the most thoroughly tested supplements on the market and is considered safe for healthy adults at normal doses. If you have kidney disease or any doubt, talk to your doctor first.
In short
For most people who train, creatine is an affordable, well-documented base — and one of the easiest habits to add to your day. One scoop, mixed with water. Do your daily.
