Creatine: More Power More Progress

When you hear the word creatine, you might picture a bodybuilder lifting weights, a powder mixed after a workout or a supplement used to build bigger muscles.

Creatine has long been associated with strength sports and bodybuilding, but interest in it has grown. It has been studied in women, recreational exercisers and older adults, and it is one of the most researched supplements in sports nutrition.

What is creatine, and how does it work? Can it cause weight gain? Can women take it? And could it be useful if building muscle isn’t your goal?

In this guide, Avnzor explores what we know about creatine and what researchers are still investigating.

What Is Creatine?

Creatine is a compound produced naturally by the body. We also get some creatine from foods such as meat and fish. Most of the body’s creatine is stored in skeletal muscles, with smaller amounts found in other tissues, including the brain.

Creatine plays a role in the body’s energy system. To understand how, it helps to know about a molecule called adenosine triphosphate (ATP), a readily available source of energy used by cells. During short, intense activities, such as weightlifting, muscles use ATP rapidly.

Muscles store some creatine as phosphocreatine, which helps regenerate ATP during high-intensity effort. Creatine may therefore help some people perform repeated, intense efforts. However, it does not build muscle on its own or replace training.

How Does Creatine Work?

After you take creatine, it is absorbed and carried through the bloodstream to body tissues, particularly the muscles. There, it helps form phosphocreatine, which contributes to ATP regeneration during intense activity.

Creatine has been studied in activities that involve short, repeated bursts of intense effort, including:

• Weightlifting.
• Sprinting and jumping.
• High-intensity interval training.
• Some team sports, such as football and basketball.

Creatine may help some people make an extra effort or complete more repetitions during training. When combined with consistent resistance training, this may support improvements in strength and lean mass. Creatine can support training, but it does not replace it, and results vary by activity and individual.

Creatine for Different People

For exercisers and athletes

You don’t need to be a competitive bodybuilder to be interested in creatine. It may be relevant for people who regularly do resistance training or take part in sports involving repeated, high-intensity efforts.

Its effects are less clear for continuous, low-intensity endurance activities. Potential benefits depend on the sport, training programme and individual needs.

For women

Creatine is not just for men. Women produce and use creatine as part of the body’s energy processes. Research has studied creatine use in women, though responses can vary depending on factors such as training, diet and individual needs.

Creatine may support performance in some intense exercise activities and may contribute to strength improvements for some women when combined with resistance training. It does not automatically lead to a large increase in muscle size; changes in muscle mass are influenced by training, nutrition, genetics and other factors.

There is not enough evidence to establish the safety of routine creatine use during pregnancy or breastfeeding. Speak with a qualified healthcare professional before considering creatine during these times.

For older adults

Maintaining strength and mobility becomes increasingly important with age. Studies have examined creatine alongside resistance training in older adults, with some findings suggesting improvements in certain measures of strength and lean mass.

Creatine is not a treatment for age-related muscle loss and cannot replace physical activity, good nutrition or medical care. Results vary across studies and individuals.

Creatine and Brain Health: What Do We Know?

Creatine is also found in the brain, where it plays a role in energy metabolism. Researchers are studying whether supplementation may affect certain aspects of cognitive performance.

Some studies have reported changes in specific cognitive tasks or under conditions, such as sleep deprivation or in some older adults. However, studies differ in their participants, doses and methods. Current evidence is not sufficient to conclude that creatine improves memory or concentration in all healthy adults.

Creatine should not be presented as a treatment for cognitive decline or as a supplement proven to improve brain performance for everyone.

What Are the Different Types of Creatine?

Creatine supplements come in several forms, but not all have the same level of supporting evidence.

Form	What we know	Consideration
Creatine monohydrate	The most researched form, with evidence supporting improvements in some measures of high-intensity exercise performance	Widely available and commonly used
Creatine hydrochloride (HCl)	Marketed as more soluble	Greater solubility does not prove better results than monohydrate
Buffered creatine	Marketed with modified properties	There is no consistent evidence that it outperforms monohydrate
Creatine gummies	A convenient format for some people	Check the creatine content per serving and product quality information

For healthy adults considering creatine to support exercise performance, creatine monohydrate is the most researched form and has the strongest evidence among commonly available types.

What Doses Are Used in Studies?

Many studies in healthy adults use around 3–5 grams of creatine monohydrate per day. This approach can gradually increase muscle creatine stores over several weeks. These are commonly studied protocols, not individual medical recommendations or a substitute for product instructions and professional advice.

Some studies use a “loading phase” to increase muscle creatine stores more quickly, followed by a lower daily amount. Loading is not essential; smaller daily amounts can increase muscle stores gradually. Larger doses may be more likely to cause digestive discomfort.

Research has not established one ideal time of day to take creatine. Many study protocols involve daily use, including on rest days, but whether this is appropriate depends on the product and individual needs. In general, consistency matters more than timing.

Does Creatine Cause Weight Gain?

Some people notice an increase in body weight after starting creatine. This is often linked to more water being stored within muscle cells and does not necessarily mean an increase in body fat.

Some people may also experience bloating or digestive discomfort, particularly after taking a large amount at once. Individual experiences vary, so follow the product instructions and don’t assume that every change in weight is fat gain.

Common Creatine Myths

“Creatine is a steroid.”

False. Creatine is a naturally occurring compound involved in the body’s energy processes. It is not an anabolic steroid.

“Creatine is only for men.”

False. Women also produce and use creatine, and research has studied supplementation in women.

“Creatine builds muscle automatically.”

False. Creatine may support performance in some types of exercise, but muscle growth depends on training, nutrition and other factors.

“Creatine causes fat gain.”

Creatine does not directly cause fat gain. Weight changes in some people may be related to water stored in the muscles.

“You must take creatine immediately after a workout.”

There is not enough evidence to show that one specific timing strategy is best for everyone. Consistency is generally more important than whether you take it before or after exercise.

“Creatine damages everyone’s kidneys.”

Current evidence does not indicate kidney damage in healthy adults using amounts commonly studied. However, this does not mean creatine is suitable for everyone. People with kidney disease or another relevant medical condition should consult a healthcare professional before using it.

Creatine may affect blood creatinine levels, which are used as part of kidney function assessments. If you use creatine and are having kidney tests, tell your healthcare professional so they can take this into account when interpreting the results.

“More creatine means better results.”

False. Higher dose do not necessarily lead to better results and may increase the chance of digestive discomfort. Follow product instructions and don’t increase your dose on your own.

Is Creatine Safe?

Creatine monohydrate is one of the most researched sports supplements. Research suggests it is generally well tolerated by many healthy adults when used at amounts commonly studied. However, no supplement is right for everyone.

Possible side effects may include:

• Digestive discomfort.
• Nausea or diarrhea.
• Changes in body weight related to water stored in muscle.

Speak with a healthcare professional before using creatine if you:

• Have kidney disease or another medical condition.
• Take medication that may affect kidney function.
• Are pregnant or breastfeeding.
• Are considering it for a child or teenager.

If you are having kidney function tests, tell your healthcare professional that you use creatine.

Creatine vs Protein: What’s the Difference?

Creatine and protein are often discussed together, but they have different roles.

Feature	Creatine	Protein
Main role	Supports ATP regeneration during intense effort	Provides amino acids
Provides the building blocks for protein?	No	Yes
Role in training	May support performance in some intense activities	Helps meet the body’s protein needs
Common supplement formats	Powder, capsules and gummies	Powder, shakes and bars

Creatine and protein can be part of the same routine because they serve different purposes. However, not everyone needs supplements. The right choice depends on your nutrition needs and training.

How to Choose a Creatine Supplement

Before buying a product, consider the following:

1. Choose a well-researched form: Creatine monohydrate is the most studied form for supporting high-intensity exercise performance.
2. Check the amount per serving: Look at the actual creatine content rather than relying on the scoop or container size.
3. Read the ingredient list: Some products include flavours, sweeteners or other ingredients.
4. Choose a product with clear information: Review the product details, expiry date and directions for use, and buy from a reputable source.
5. Compare value: Compare products based on the total amount of creatine, not just the container price.
6. Choose a format that suits your routine: Creatine is available as powder, capsules and gummies. Check the serving size and product information.

The best supplement is not necessarily the most expensive. Look for an appropriate formulation, clear labelling and reliable product quality.

Your Strength, Your Routine, Your Progress

Creatine has long been associated with bodybuilding, but research has explored its use more broadly. It is part of the body’s natural energy system and may support performance in some types of intense exercise. Researchers are also studying its potential role in women’s fitness, strength as people age and energy metabolism in the brain.

Not every proposed benefit has been established, and creatine is not a quick fix or a replacement for balanced nutrition and physical activity. It may, however, be an option for some people, particularly those who regularly do resistance training.

At Avnzor, we believe progress starts with knowledge and choosing what suits your needs and routine.
