What does creatine do?

In the world of sports nutrition and fitness, few supplements have garnered as much attention and scientific scrutiny as creatine. This naturally occurring compound, found in small amounts in certain foods and synthesized within the human body, has become a staple for athletes, bodybuilders, and fitness enthusiasts alike. But what does creatine do, and why has it earned such widespread popularity? In this comprehensive guide, we will delve into the science and benefits of creatine supplementation.

What is creatine?

Before diving into its benefits, it’s crucial to understand what creatine is. Creatine is a naturally occurring compound that plays a vital role in the production of energy during short bursts of intense physical activity. It is synthesized in the body from amino acids, primarily in the liver, kidneys, and pancreas. Additionally, you can obtain creatine through dietary sources like red meat and fish.

In its supplemental form, creatine is usually found as creatine monohydrate, which is highly bioavailable and well-studied. When ingested, creatine monohydrate is rapidly absorbed into the bloodstream and stored in muscle tissue as phosphocreatine.

How does creatine work?

To understand what creatine does, we need to examine its role in energy metabolism. During high-intensity activities like weightlifting, sprinting, or jumping, your muscles require a rapid supply of adenosine triphosphate (ATP), the primary energy currency of cells. ATP provides the energy necessary for muscle contractions.

When your muscles contract, ATP is broken down into adenosine diphosphate (ADP), releasing energy in the process. However, the body’s ATP stores are limited and quickly depleted during intense exercise. This is where creatine steps in.

Creatine stores in muscle tissue can donate a phosphate group to ADP, effectively converting it back into ATP. This ATP regeneration process allows your muscles to continue contracting with energy during short bursts of high-intensity exercise, delaying the onset of fatigue. In essence, creatine enhances your body’s capacity to perform explosive movements, making it a valuable asset for athletes and fitness enthusiasts.

What are the benefits of supplementing creatine?

Now, let’s explore the myriad of benefits that creatine supplementation offers:

1. Improved Exercise Performance

One of the most well-established benefits of creatine is its ability to enhance exercise performance, particularly in activities that involve short bursts of high-intensity effort. Creatine has been shown to improve strength, power, and performance in activities like weightlifting, sprinting, and jumping. Athletes and bodybuilders often experience increased workout capacity, allowing them to train harder and for longer durations.

2. Increased Muscle Mass

Creatine’s role in enhancing muscle performance also translates to muscle growth. When athletes can lift heavier weights or perform more reps during resistance training, it leads to greater muscle stimulation and, ultimately, increased muscle hypertrophy (growth). Over time, creatine supplementation can contribute to significant gains in muscle mass, particularly when combined with proper nutrition and training.

3. Enhanced Recovery

Creatine may also aid in post-exercise recovery. Some studies suggest that creatine supplementation reduces muscle cell damage and inflammation following intense exercise. This can lead to quicker recovery times between workouts and potentially reduce the risk of overtraining and injury.

4. Cognitive Benefits

Emerging research indicates that creatine may have cognitive benefits as well. Creatine is found in the brain and plays a role in brain energy metabolism. Some studies suggest that creatine supplementation may enhance cognitive functions such as memory, attention, and mental clarity. While more research is needed in this area, the potential cognitive benefits of creatine are promising.

5. Neuroprotective Properties

Creatine’s influence extends beyond exercise and cognition. Research has suggested that creatine may have neuroprotective properties and could be beneficial in conditions like Parkinson’s disease, Alzheimer’s disease, and certain neuromuscular disorders. These potential applications are still under investigation, but they highlight the versatility of creatine in promoting overall health.

6. Enhanced Endurance

Although creatine is primarily associated with short bursts of high-intensity exercise, some studies have suggested that it might also have benefits for endurance athletes. Creatine can enhance the body’s capacity to buffer and remove lactic acid, potentially delaying the onset of fatigue during prolonged endurance activities.

7. Potential for Injury Prevention

Due to its role in reducing muscle damage and inflammation, creatine may also have a role in injury prevention. Athletes and individuals engaged in physically demanding activities may experience fewer injuries and recover more quickly when using creatine as part of their training regimen.

How should you use creatine?

If you’re considering creatine supplementation, it’s essential to use it correctly to maximize its benefits. Here’s a step-by-step guide on how to use creatine effectively:

1. Choose a High-Quality Creatine Supplement: Look for creatine monohydrate, as it is the most researched and widely used form. Ensure the product is from a reputable manufacturer.

2. Loading Phase (Optional): Some people choose to do a loading phase of creatine, which involves taking a higher dose (typically 20 grams per day) for 5-7 days to quickly saturate muscle stores. However, this is not necessary, as you can achieve the same results by taking a lower dose over a more extended period.

3. Maintenance Phase: After the loading phase (if you choose to do it), continue with a maintenance dose of 3-5 grams of creatine per day. This smaller dose is sufficient to keep your muscle creatine stores saturated.

4. Timing: Creatine can be taken at any time of day, but many people prefer to take it immediately before or after their workouts. Mixing it with a carbohydrate source can enhance its absorption.

5. Stay Hydrated: Creatine can cause increased water retention in muscle cells, so it’s essential to stay well-hydrated when using it.

6. Combine with Proper Nutrition and Training: Creatine is most effective when combined with a balanced diet and a well-structured training program. Make sure your overall nutrition supports your fitness goals, and tailor your workouts to your specific objectives.


Creatine is a powerhouse supplement with a wide range of benefits for athletes, fitness enthusiasts, and individuals looking to improve exercise performance and muscle growth. Its ability to enhance ATP regeneration in muscles, improve strength and power, and potentially offer cognitive and neuroprotective advantages makes it a valuable addition to many fitness regimens.

As with any supplement, it’s essential to use creatine responsibly, following recommended dosages and maintaining a well-rounded approach to fitness, including proper nutrition and training. While creatine is generally considered safe, it’s advisable to consult with a healthcare professional before starting any new supplementation regimen, especially if you have underlying health concerns.
