Creatine is one of the most researched supplements in strength training. It can improve performance in repeated, short, and intensive activities, thereby helping you get more quality out of your working sets.
However, creatine is not necessary to achieve results. A good training program, sufficient sleep, and a varied diet still come first. Consider creatine a supplement to basic habits – not a shortcut.
What is creatine?
Creatine is a natural substance that the body produces itself and is also found in meat and fish, among other things. Most of the body's creatine is stored in the muscles.
In the muscles, creatine is part of the body's system for rapid energy supply. It helps regenerate adenosine triphosphate, better known as ATP, which muscles use as energy during short and intensive activities.
When you supplement with creatine, the amount of creatine and creatine phosphate in the muscles can increase. This can improve your ability to perform repeated strenuous efforts such as heavy lifting, sprinting, and explosive movements.
What does creatine do for strength training?
Creatine can be particularly relevant in training with short, intensive working sets. It can, among other things, help you to:
- Perform more quality repetitions over several sets
- Maintain high work intensity
- Improve strength and explosive performance over time
- Get more out of a structured strength training program
The effect does not necessarily manifest as an immediate increase in your maximum lift. For many, the benefit is instead that they can do a little more work throughout their training sessions. Over a longer period, the increased training quality can support progress in strength and muscle mass.
Which type of creatine should you choose?
Creatine monohydrate is the most researched form of creatine. It is usually also the cheapest variant.
There are products such as creatine ethyl ester, buffered creatine, and various creatine blends. However, existing evidence does not show that these forms generally provide better absorption or effect than regular creatine monohydrate.
Therefore, you do not need to choose the most expensive or advanced variant. A standard product with creatine monohydrate is a sensible choice for most people.
How much creatine should you take?
A common maintenance dose is 3–5 grams of creatine monohydrate per day. It should be taken regularly, even on days when you do not train.
You do not need to adjust the dosage precisely according to your body weight. For most exercisers, 3–5 grams per day is a simple and practical starting point.
Is a loading phase necessary?
No. A loading phase can fill the muscle's creatine stores more quickly but is not necessary to achieve the effect.
A traditional loading phase typically consists of approximately 20 grams daily divided into four smaller doses for five to seven days. After that, you continue with 3–5 grams per day. Alternatively, you can start directly with 3–5 grams daily. It just takes longer for the muscle's creatine stores to become saturated.
When should creatine be taken?
The most important thing is that you take creatine regularly. The exact time of day is less important than daily continuity.
You can mix creatine in water, juice, a protein shake, or take it with a meal. Choose the time that makes it easiest for you to remember it every day.
Does creatine cause weight gain?
Some experience a slight increase in body weight, especially initially. This is primarily because creatine can increase the amount of fluid in muscle cells.
This is not the same as gaining fat. How much weight changes varies from person to person and depends, among other things, on dosage, diet, body size, and starting point.
Weight gain can occur more quickly with a loading phase. If you start directly with a regular daily dose, the change will often happen more gradually.
Does creatine work for everyone?
The effect varies from person to person. Some notice a clear difference in their training capacity, while others experience a smaller change.
The baseline creatine content of the muscles can be influenced by diet, among other things. People who eat very little meat and fish may have lower creatine stores and may therefore, in some cases, experience a more noticeable change.
It is difficult to assess the effect from individual training sessions. If you want to investigate how creatine affects your training, you should follow your program, repetitions, and loads over a longer period.
Is creatine safe?
Creatine monohydrate is generally considered safe for healthy adults when used in normal doses. Some may experience mild stomach upset, especially if a large amount is ingested at once. In that case, the dose can be divided or reduced.
If you have kidney disease, are pregnant or breastfeeding, are taking medication, or are unsure whether creatine is suitable for you, you should speak to your doctor or another healthcare professional first.
Should you take a break from creatine?
There is usually no need to cycle creatine. You can take a regular daily dose continuously. If you stop, the muscle's creatine levels will gradually return to baseline.
What is more important than supplements?
Creatine can support your training, but it cannot replace:
- A training program with gradual progression
- Sufficient protein and a varied diet
- Enough sleep and recovery
- Good technique and appropriate load
- Continuity over a long period

When grip limits training
Creatine can help with energy supply during intensive working sets, but it does not solve a grip that fails before the back or hamstrings. Here, lifting straps can be a relevant tool in exercises such as deadlifts, rows, and lat pulldowns.

Frequently asked questions about creatine
How much creatine should I take per day?
A daily dose of 3–5 grams of creatine monohydrate is a common starting point for healthy adults.
Should creatine be taken on non-training days?
Yes. Creatine works by gradually increasing the muscle's creatine stores, so it should also be taken on non-training days.
Should I take creatine before or after training?
The exact timing is less important than regular daily use. Take it at the time that best fits into your daily routine.
Is a loading phase necessary?
No. A loading phase fills the stores more quickly, but you can achieve the same saturation more gradually by taking 3–5 grams daily.
Is weight gain from creatine fat?
No. Any rapid weight gain is primarily due to increased fluid in muscle cells and not increased fat mass.
