Creatine: the one supplement that actually works

How much creatine, when to take it, whether you need a loading phase, what happens with water weight, and why it is the only powder worth buying as a beginner.

Out of the hundreds of products in supplement shops, three have serious scientific backing: protein (which is food), caffeine and creatine monohydrate. Creatine is the most researched supplement in sport — hundreds of studies over more than 30 years.

What creatine does

Creatine helps your body regenerate ATP, the fuel for short, powerful efforts. In practice: you get one or two extra reps per set, and over months that means more total work, more muscle and more strength. The effect is not dramatic overnight — expect roughly 5–10 % more strength after a few weeks, which is a lot for something that costs about the same as two coffees a month.

How much and when

Dose: 3–5 g a day, every day, with no breaks.
Timing: it does not matter. Morning, evening, before or after training — no difference. What matters is not skipping days, because the effect comes from muscle saturation, not from a single dose.
With what: water, juice, protein, coffee — anything works. Caffeine does not "kill" creatine; that story comes from one study back in 1996.

Do you need a loading phase?

No. Loading (20 g a day split into 4 doses for 5–7 days) only saturates the muscle faster — in a week instead of three to four weeks. The end result is identical. If you are not in a hurry, take 5 g a day from day one.

Which form to buy

Creatine monohydrate — the plainest and cheapest. Everything else (HCl, kre-alkalyn, "liquid creatine", nitrate) costs more with no proven advantage. If the tub says Creapure, that is a purity guarantee — it does not work better, but it is a safe choice.

Water, weight and looking "puffy"

Creatine pulls water into the muscle cell, not under the skin. In the first weeks the scale goes up 1–2 kg — that is water inside muscle, not fat. Muscle looks fuller, not bloated. Stop taking it and that water leaves again.

Safety

In healthy people, long-term use of 3–5 g a day has shown no harm to kidneys or liver in studies running up to five years. Two pieces of real advice:

Drink normal amounts of water (2–3 litres a day).
If you have kidney disease or take medication, ask your doctor before starting — that goes for any supplement.

Mild bloating or cramps in some people are usually solved by splitting the dose into two servings of 2.5 g with meals.

Does it work for everyone

In roughly 20–30 % of people the effect is small or unnoticeable — typically in those who eat a lot of red meat and fish, so their muscles are already near saturation. There is no test for it; if you see no difference in your numbers after 6–8 weeks, simply stop.

What NOT to buy as a beginner

BCAAs — pointless if you eat enough protein.
Pre-workout blends — you pay five times over for caffeine and a tingling sensation. Coffee does the same job.
Fat burners — not one has a meaningful effect; the deficit does the work.
Testosterone boosters — in healthy people they do not raise testosterone anywhere near enough to matter.
