Creatine, Explained Properly (No Hype, No Scare Stories)

Creatine is the second thing people buy after protein powder, and the first thing their family warns them about. "Later kidney damage." "Confirm got steroid inside." "You will retain water and look bloated."

Most of that is wrong. Here's the actual picture.

What it is

Creatine is a compound your body already makes — roughly 1–2g a day, in your liver and kidneys — and that you also eat, mainly in red meat and fish. It's stored in muscle and used to regenerate ATP, the fuel for short, hard efforts.

Supplementing tops up those stores beyond what diet alone provides. More stored creatine means slightly more work before fatigue: an extra rep or two, not a transformation.

It is not a steroid. It's not hormonal, it's not banned, and it's not exotic — you ate some at lunch if you had fish soup.

What it actually does

The evidence here is unusually strong. Creatine is among the most-studied supplements in existence, and the consistent findings are:

• More strength and power output in short, high-intensity work
• More lean mass over time, partly from training harder, partly from water drawn into muscle
• Better performance in repeated sprints and similar efforts

What it doesn't do: burn fat, improve endurance running, or do anything much if you don't train. Creatine makes hard training slightly more productive. Without the training there's nothing to amplify.

How to take it

Refreshingly simple:

• 3–5g a day, every day. That's it.
• Timing doesn't matter. Take it whenever you'll remember.
• Loading is optional. 20g a day for a week fills your stores faster, but 5g daily gets to the same place in three to four weeks, with less stomach upset. Skip it.
• Take it on rest days too. You're maintaining a stored level, not fuelling a session.

Which form? Creatine monohydrate. It's the form used in nearly all the research, and it's the cheapest. The fancier versions — HCl, ethyl ester, buffered — cost more and have never convincingly beaten monohydrate. Look for Creapure if you want a purity marker.

At 3–5g a day, a 500g tub lasts three to five months. It's one of the cheapest supplements going.

The kidney question

Let's address it directly, since it's the reason half of Singapore avoids it.

In people with healthy kidneys, creatine at normal doses has not been shown to cause kidney damage. This has been looked at repeatedly, including in multi-year studies.

The confusion comes from a blood test. Creatine breaks down into creatinine, and blood creatinine is what doctors measure to estimate kidney function. Supplementing raises creatinine without any change in actual kidney function — so a routine blood test can look alarming when nothing is wrong.

Practical advice: tell your doctor you take creatine before any blood test. That one sentence prevents an unnecessary scare and possibly an unnecessary referral.

The real exception: if you already have kidney disease, or any diagnosed kidney condition, ask your doctor before starting. That advice is genuine and it's not the same as the general scare.

The water weight thing

Yes, creatine pulls water into your muscle cells. Expect 1–2kg on the scale in the first few weeks.

This is intramuscular, not under your skin — it doesn't make you look puffy, it makes muscles look slightly fuller. But if you're weighing yourself daily and panicking at a 1.5kg jump, now you know why.

Who it's actually for

Worth it: anyone doing resistance training who wants a small, reliable, cheap edge. Also increasingly studied for older adults alongside resistance work, for the same muscle-preservation reasons in our protein for aunties and uncles post.

Not worth it: if you don't train. Nothing to amplify.

Vegetarians may notice more. Creatine comes mainly from meat and fish, so vegetarians typically start with lower stores and often report a larger effect.

Halal and dietary notes

Creatine monohydrate is synthesised, not animal-derived — the raw materials are sarcosine and cyanamide, both industrial. The powder itself is generally fine. The things to check are the same as always: capsule shells (gelatin), and flavoured or blended products with added ingredients. Plain unflavoured monohydrate powder avoids both.

The short version

• 3–5g of monohydrate daily, timing irrelevant, no loading needed.
• Not a steroid. Your body makes it and you eat it.
• Healthy kidneys: not a concern — but mention it before a blood test.
• 1–2kg of water gain is normal and is inside the muscle.
• Useless without training. It amplifies work, it doesn't replace it.

Protein first, though. Creatine on top of a diet that misses your protein target is decorating a house with no roof. Work out your number first.

Educational only, not medical advice. If you have kidney disease, are pregnant, or take regular medication, ask your doctor before starting any supplement.
