Creatine – One of the Best-Researched Supplements

Creatine is one of the most researched and widely used supplements in the world of fitness and sports. Unlike many products that come with big promises, creatine has strong scientific support behind it.

For people who do strength training, it can be a simple and effective addition to a good diet and structured training program.

What is creatine?

Creatine is a substance naturally produced by the body and stored mainly in our muscles. It is also found in foods such as meat and fish.

Its main role is to help the muscles produce energy during short, intense activities such as weight training, sprinting and explosive exercise.

By increasing the amount of creatine stored in the muscles, supplementation can improve the body’s ability to perform repeated high-intensity efforts. (SpringerLink)

Why is creatine good for strength training?

The biggest benefit is simple: creatine can help you train harder and perform better.

Research shows that combining creatine with resistance training can lead to greater improvements in strength compared with training alone. A 2024 systematic review found significant improvements in both upper- and lower-body strength when creatine was combined with resistance training. (PubMed)

This matters because better training performance over time can contribute to better muscle development.

Creatine is not a magic powder that builds muscle by itself. Training, nutrition and recovery are still the foundation.Creatine is simply a tool that can help you get more out of your training.

Creatine and muscle mass

Creatine can also support increases in lean body mass when combined with resistance training.

A 2024 meta-analysis found that people using creatine during resistance training gained, on average, around 1.14 kg more lean body mass than those doing resistance training without creatine. (PubMed)

Some of the early increase in body weight is caused by greater water storage inside the muscles. This is not the same as gaining body fat.

Over time, however, the combination of creatine and consistent resistance training can support real improvements in muscle development.

How much creatine should you take?

For most people, there is no need to make things complicated.

A practical approach is:

3–5 grams of creatine monohydrate every day.

You do not have to take it immediately before or after training. The important thing is consistency.

You can take it with water, a protein shake or a meal. On rest days, simply take your normal daily dose.

Do you need a loading phase?

No.

Some people use a loading phase of around 20 grams per day for several days to saturate the muscles faster. However, it is not necessary.

Taking a smaller daily dose will also increase muscle creatine stores; it simply takes a little longer.

For most people, 5 grams every day is simple and effective.

Which type of creatine should you choose?

The answer is straightforward:

Creatine monohydrate.

It is the form used in a large amount of scientific research and is generally inexpensive.

There are many different forms of creatine on the market, often with impressive-sounding names and higher prices. But for most people, there is little reason to spend extra money.

Keep it simple.

Is creatine safe?

Creatine has a long history of research and is generally considered safe for healthy adults when used appropriately. Research has not found convincing evidence that normal creatine supplementation causes harm in healthy people. (SpringerLink)

As with any supplement, people with existing medical conditions should discuss supplementation with a healthcare professional before starting.

The bottom line

Creatine is not a miracle supplement. And you don’t need ten different supplements to make progress.

A good training program, enough protein, sensible nutrition, sleep and consistency come first.

But if you want to add one simple, well-researched supplement, creatine is one of the strongest choices.

3–5 grams of creatine monohydrate per day can help support strength, training performance and lean muscle mass.

Sometimes the old-fashioned approach is still the best: train hard, eat well, recover properly and keep doing it consistently.
