What is creatine and how does it help you with sport?

You have probably heard people talking about creatine at the gym, or even while queuing at the supermarket. For years, this supplement has been surrounded by myths, almost as if it were a “magic potion” reserved for elite bodybuilders. In reality, things are far simpler and more scientific. Creatine is neither a steroid nor a synthetic lab product, but a compound produced naturally by the body and found in foods such as steak and salmon.

So, what exactly is creatine? In simple terms, it is a quick source of energy stored in the muscles. Because the body’s natural supply is limited and quickly used up during intense exercise, supplementing it can help improve performance. Understanding how this “fuel” works is the first step in deciding whether it can support your training goals, without falling for common myths.

Key benefits of creatine

There is strong scientific evidence to show that creatine is one of the most researched and safest supplements available. But what is it actually used for? Its main role is to support rapid energy production. You can think of your muscles as an engine and creatine as a temporary boost that helps maintain power during short, intense efforts.

Among the benefits of creatine, the following stand out:

• Increased strength and power. It helps regenerate ATP, the body’s main energy molecule, more quickly. This can make a difference when pushing through that final repetition.
• Improved performance in high-intensity exercise. Particularly useful for activities such as sprinting, jumping or interval training, where quick bursts of energy are needed.
• Better muscle recovery. It may help reduce inflammation and muscle damage after intense exercise, allowing you to train again sooner.
• Cognitive health: Some recent studies suggest it could also help with memory and mental fatigue.

How to take creatine properly

The key is to tailor it to your needs. A typical dose is around 3 to 5 grams per day, although it can also be calculated based on body weight, roughly 0.08 to 0.10 grams per kilogram.

One important point is that you do not have to take the full dose all at once. The daily amount can be split into smaller doses, which may make it easier to tolerate if you prefer to spread them across your main meals. To maximise absorption, it is recommended to take creatine alongside a carbohydrate source (such as juice or a piece of fruit), as this may help it enter the cells more efficiently. 

When to take creatine: before or after training

For many people, this is the key question: when should creatine be taken to maximise its effects? General guidance suggests taking it 30 to 60 minutes before exercise, as peak blood levels are reached around one hour after ingestion, which coincides with the start of physical effort.

However, when looking into this topic, you are likely to come across conflicting studies. Some support pre-exercise intake, while others favour the post-exercise recovery window. Ultimately, experts agree that exact timing is largely a matter of personal preference.

The most important thing is consistency, rather than precise timing. It is far more important to take your daily dose regularly than to focus on the exact moment, as it is consistent intake that increases muscle creatine stores. A practical approach is to take it within 15 to 30 minutes before or after your workout. For convenience, you can easily add it to your usual post-workout shake. The key is to maintain the habit, even on rest days. 

Foods containing natural creatine

Although supplements can be convenient, a healthy, varied diet remains the best foundation. In fact, creatine can also be obtained naturally through food. The richest sources include herring, tuna, salmon, red meat (such as beef and pork), chicken and egg whites.

As you can see, there are no hidden secrets to creatine, just solid science and a straightforward mechanism of action. While incorporating it into your routine will not replace hard work, it can provide that extra boost to help your muscles and mind perform at their best. So, in summary: train hard, eat well, and if you choose to use supplements, always do so sensibly.
