Creatine is one of the most researched ingredients in sports nutrition—and creatine monohydrate is the form most commonly studied.

It is naturally produced by the body and is also found in foods such as meat and fish. Inside the muscles, creatine helps support the production of energy during short, intense bursts of physical activity.

But what exactly does creatine do, who may benefit from it, and how should you approach supplementation?

Let's break it down.

What Is Creatine?

Creatine is a naturally occurring compound stored primarily in skeletal muscle.

Your body produces creatine on its own, while dietary sources—particularly animal-based foods—provide additional amounts.

The muscles use creatine to help regenerate ATP, a primary energy source used during short-duration, high-intensity activity.

This makes creatine particularly relevant to activities such as:

• Weight training
• Sprinting
• Jumping
• Repeated high-intensity exercise
• Short bursts of power-based activity

Creatine is less relevant to purely endurance-based activities such as long-distance running.

What Is Creatine Monohydrate?

Creatine monohydrate is a specific form of creatine.

It is also the most widely studied form of supplemental creatine. Other forms are available, but current evidence has not established that more expensive alternative forms are superior to creatine monohydrate for increasing muscle creatine levels or improving performance.

This is one reason creatine monohydrate remains a popular choice among athletes and active individuals.

How Does Creatine Work?

Think of your muscles as having a rapidly accessible energy system.

During intense exercise, your body needs ATP quickly.

Creatine contributes to the phosphocreatine system, which helps regenerate ATP during short periods of high-intensity effort.

A simplified process looks like this:

Creatine → Phosphocreatine → ATP regeneration → Short-term energy availability

This system becomes particularly important during repeated maximal or near-maximal efforts.

That's why creatine is associated more strongly with strength, power, and repeated high-intensity exercise than with long-duration endurance activities.

What Are the Potential Benefits of Creatine?

Research has consistently investigated creatine in relation to several areas of exercise performance.

1. Strength Support

Creatine supplementation can help increase strength when combined with resistance training.

The benefit isn't simply from taking creatine on its own.

It works alongside a structured training program by helping support repeated high-intensity efforts.

2. Power and Explosive Performance

Activities involving short bursts of maximal effort can benefit from greater availability of the phosphocreatine energy system.

This includes exercises such as:

• Heavy lifting
• Sprinting
• Jumping
• Repeated explosive movements

3. Training Capacity

Creatine can support performance during repeated high-intensity efforts.

Over time, this can help people complete structured training programs with greater training capacity.

4. Lean Mass During Training

When creatine is combined with resistance training, studies have reported improvements in training-related gains in lean body mass and strength.

However, individual responses vary.

Nutrition, training experience, diet, and other factors all influence results.

Does Creatine Build Muscle Directly?

This is an important distinction.

Creatine isn't a hormone or anabolic drug.

Instead, it can support the ability to perform repeated high-intensity exercise.

That training stimulus, combined with adequate nutrition and recovery, contributes to long-term adaptations.

Creatine can also increase water retention within muscle, which can contribute to an increase in body weight.

So an increase on the scale after starting creatine isn't necessarily the same thing as gaining body fat.

Who May Benefit From Creatine?

Creatine may be particularly relevant for people participating in:

• Strength training
• Resistance training
• Sprinting
• Power sports
• High-intensity interval training
• Sports involving repeated bursts of intense activity

It tends to be less useful for activities that rely primarily on prolonged aerobic endurance.

How Much Creatine Should You Take?

Research commonly uses two approaches.

Option 1: Loading Phase

A commonly studied loading protocol is approximately:

20 g per day for 5–7 days, usually divided into several smaller servings.

This is followed by:

3–5 g per day as a maintenance amount.

Option 2: No Loading Phase

You can also take approximately 3–5 g per day without a loading phase.

This approach takes longer to build up muscle creatine stores but avoids the need for a higher initial intake.

The important point is that a loading phase isn't mandatory.

Does Creatine Need to Be Taken Before a Workout?

Not necessarily.

Creatine works by increasing and maintaining muscle creatine stores over time.

Therefore, consistent daily intake is generally more important than taking it at a specific minute before or after training.

If taking it after breakfast or alongside another daily habit helps you remember, that's a practical approach.

Does Creatine Cause Weight Gain?

It can.

One of the most common effects of creatine supplementation is an increase in body weight related to increased water retention.

This is different from gaining body fat.

The amount of weight change varies between individuals.

If you're monitoring your body weight, keep this potential change in mind when evaluating progress after beginning creatine.

Is Creatine Safe?

Creatine monohydrate has a substantial research history.

Evidence summarized by the U.S. National Institutes of Health indicates that creatine is considered safe for healthy adults when used appropriately, including evidence supporting longer-term use.

Some people may experience gastrointestinal discomfort or other unwanted effects, while increased water retention and body weight are more commonly recognized effects.

If you have a medical condition, take medications, or have concerns about kidney health, speak with a qualified healthcare professional before using creatine.

Do You Need to Drink More Water With Creatine?

Adequate hydration is important whether or not you use creatine.

Because creatine can increase water retention, maintaining normal fluid intake is a sensible part of an active lifestyle.

Don't interpret this as needing to force excessive amounts of water.

Instead:

Drink regularly.

Pay attention to exercise and environmental conditions.

Replace fluids lost through sweating.

Avoid excessive water consumption.

Creatine and Vegetarians

Diet can influence baseline creatine stores.

Because meat and fish provide dietary creatine, people who consume little or no animal products may have lower dietary creatine intake.

Research suggests that individual responses to creatine can vary depending partly on diet and baseline muscle creatine levels.

This doesn't mean everyone following a plant-based diet needs creatine, but it is one factor worth considering when discussing supplementation.

Creatine Doesn't Replace the Basics

Creatine is not a substitute for:

• Adequate protein
• Balanced nutrition
• Hydration
• Quality sleep
• Proper training
• Recovery

A useful hierarchy is:

Training → Nutrition → Recovery → Consistency → Supplementation

Get the fundamentals right first.

Then consider whether a supplement fits your goals.

How to Choose a Creatine Product
