Creatine used to be something you'd only hear about in the corner of the gym where the heaviest weights live. Today it turns up everywhere: in rugby change rooms, on running club WhatsApp groups, in wellness podcasts and on pharmacy shelves across South Africa. It's now available as powders, gummies and hydration drinks, and it's being studied for everything from sprint performance to brain health.
With that much attention comes a lot of confusion. Is creatine a steroid? Will it make you bloated? Is it only for bodybuilders? Is it even allowed in competitive sport?
The short answer is that creatine is one of the most thoroughly researched and best-supported supplements available. Below, we'll explain what creatine actually is, how it works in your body, what the science says it can (and can't) do, and how to decide whether it's worth adding to your routine.
What Is Creatine?
Creatine is a natural compound made from three amino acids: arginine, glycine and methionine. Your liver, kidneys and pancreas produce roughly 1g of it a day, and you get about the same amount again from food, mainly red meat and fish.
Around 95% of the creatine in your body is stored in your skeletal muscle, mostly as a molecule called creatine phosphate. The rest sits in the brain, heart and other tissues.
So creatine isn't a synthetic performance drug or a hormone. It's a nutrient your body already makes and uses every day. A creatine supplement is a form of supplementation that helps maintain or raise creatine levels beyond what your diet and natural production can provide.
How Does Creatine Work?
Every muscle contraction runs on a molecule called ATP (adenosine triphosphate), your body's immediate energy currency. During hard muscle work, ATP is broken down into adenosine diphosphate, and your muscles only hold enough ATP for a few seconds of all-out effort.
This is where creatine phosphate comes in. It acts as a rapid energy source for ATP regeneration, keeping your fastest energy system running during short, intense bursts, such as:
-
A heavy set of squats or bench press
-
A sprint to the try line or a netball fast break
-
A hill surge on a Sunday morning ride
-
Repeated high-intensity intervals in a CrossFit or HIIT class
When you supplement with creatine, you increase the amount of phosphocreatine stored in your muscles, typically by 20–40%. More stored fuel means you can regenerate ATP faster, squeeze out an extra rep or two, and recover more quickly between efforts, which supports energy production during short, powerful movements. Over weeks and months, that extra training volume adds up to real gains in strength and muscle.
Can't You Just Get Enough Creatine From Food?
In theory, yes. In practice, it's difficult. To get the 3–5g a day used in most research, you'd need to eat around a kilogram of raw beef or fish every day, and cooking destroys some of the creatine. Even a generous Saturday braai won't get you there consistently.
Vegetarians and vegans tend to have lower natural creatine stores because plant foods contain virtually none. Research suggests they often see an even greater benefit from supplementing.
What Are the Proven Benefits of Creatine for Muscle Growth?
The International Society of Sports Nutrition describes creatine monohydrate as the most effective nutritional supplement currently available for increasing high-intensity exercise capacity and lean body mass during training. There is strong scientific evidence for creatine supplementation, and here's what the research consistently supports:
-
Greater strength and power: creatine improves muscle strength and exercise performance in short, explosive efforts such as lifting, sprinting and jumping.
-
More lean muscle: combined with resistance training, creatine supports muscle building and muscle growth over time, partly by supporting protein synthesis rather than only shifting scale weight.
-
Better repeated-sprint performance: particularly useful for stop-start sports like rugby, soccer, hockey, netball and tennis.
-
Faster recovery: some studies show reduced muscle damage and inflammation after hard sessions, helping you bounce back sooner.
-
Support for healthy ageing: creatine combined with strength training may help older adults preserve muscle mass and strength, reduce muscle breakdown, and may also support bone density.
-
Emerging brain benefits: because the brain also relies on phosphocreatine for energy, researchers are studying creatine's effects on memory and mental fatigue, especially during sleep deprivation. The early results are promising but still developing.
What creatine won't do is replace training. It helps you train harder, supports better training performance and physical performance, and that harder training is what drives results
Is Creatine a Steroid? Is It Banned in Sport?
No on both counts. Creatine is not a hormone and works nothing like anabolic steroids. It is also not on the World Anti-Doping Agency's prohibited list, which the South African Institute for Drug-Free Sport (SAIDS) follows.
The real risk for competitive athletes is contamination, not creatine itself. Poorly manufactured supplements can contain undeclared substances. That's why it matters to choose brands that list every ingredient and dose, avoid proprietary blends, and follow strict quality control.
What About Water Retention and Side Effects?
When you start taking creatine, you may gain around 1–2kg in the first few weeks. This is mostly because creatine draws water into your muscle cells, where it is stored. It isn't fat, and it isn't the puffy under-the-skin bloating many people worry about. It's also part of why muscles can look fuller. Stay well hydrated, and note that some people take it with carbohydrates to improve uptake or reduce stomach discomfort.
For healthy adults, creatine has an excellent safety record at the recommended doses, including in long-term studies. We cover the most common concerns, including kidneys, hair loss and cramping, in [Creatine Side Effects: Separating Fact From Fiction].
Who Should Take Creatine for Healthy Ageing?
Creatine isn't only for bodybuilders; creatine supplements can also benefit:
-
Gym-goers and strength athletes who want support for muscle building
-
Team-sport players in rugby, soccer, netball and hockey
-
Endurance athletes who include hills, sprint finishes or strength work
-
Women who want to build strength and lean muscle without "bulking up," with possible differences in brain creatine stores (see [Creatine for Women: Benefits, Myths and How to Get Started])
-
Vegetarians and vegans with naturally lower creatine stores
-
Older adults who want to maintain muscle and strength as they age
If you have kidney disease, are pregnant or breastfeeding, are under 18, or take chronic medication, speak to your doctor before starting creatine.
How to Take Creatine
How Much Creatine Should You Take Per Day? Dosage, Loading and Timing Explained
Most people do well with 3–5g a day through consistent creatine supplementation, including on rest days. Timing matters much less than consistency, because creatine works by gradually saturating your muscle stores rather than acting like a pre-workout. It can also be taken in combination with protein or beta alanine, depending on the rest of your routine. Some people use a short "loading phase" to saturate their muscles faster, but it isn't essential.
Choosing the Right Creatine Monohydrate for You
Creatine monohydrate is the form behind most of the research, so it's the one to look for. From there, the best format is the one you'll actually take every day, whether that's a classic creatine monohydrate powder or a more convenient alternative:
-
[NutriCon Creatine Monohydrate] is the classic option: one 5g scoop of pure creatine monohydrate mixed into water or your post-workout shake, with no fillers and full label transparency.
-
[NutriCon Creatine Gummies] use CreHytine™, a hydrogel-buffered creatine monohydrate designed to stay stable in gummy form. They suit anyone who dislikes powders or wants their creatine on the go, and come in cherry, apple and mango flavours.
-
[NutriCon Hydreatine] combines a full 5g dose of pure creatine with sodium, potassium and magnesium in one sachet. It's ideal for hot South African summers and high-sweat training days.

Frequently Asked Questions
What does creatine do for your body?Creatine supplementation increases the creatine phosphate stored in your muscles, which your body uses to quickly regenerate ATP and support energy production during intense exercise. This supports strength, power, training volume and recovery.
How long does creatine take to work?With a standard 3–5g daily dose, your muscles typically reach full saturation in about three to four weeks. With a loading phase, it takes about a week.
Do I need to take creatine on rest days?Yes. Taking it daily keeps your muscle stores topped up, which is what drives the benefits.
Can I take creatine with protein powder?Absolutely. Mixing your creatine into a post-workout protein shake is one of the easiest ways to stay consistent, and this combination is common and easy for daily supplementation. See our [Beginner's Guide to Protein Powder] for more.
Will creatine make me gain fat?No. Creatine contains no calories to speak of. Any early weight gain is water stored inside the muscle cells, and any later gain is lean muscle from better training.
Should I cycle creatine?There's no strong evidence that you need to cycle on and off creatine. Most people take it continuously at a maintenance dose.
