What Is Creatine?

Creatine is a naturally occurring compound made in small amounts by the body from amino acids and found in foods such as red meat and seafood. It's stored mainly in skeletal muscle, where it helps regenerate adenosine triphosphate (ATP), the body's primary energy source for short bursts of high-intensity activity.

As a dietary supplement, creatine is one of the most widely researched ingredients in sports nutrition. Used alongside a suitable training program and balanced diet, it may help improve performance during repeated bouts of high-intensity exercise, such as resistance training or sprinting.

What Are the Benefits of Creatine Supplements?

According to the International Society of Sports Nutrition, creatine supplementation may help:

• Support increases in training capacity, which can contribute to muscle growth over time
• Improve strength and power output during resistance and sprint training
• Speed recovery between high-intensity efforts
• Support repeated high-effort performance during tough sessions
• Support cognitive performance under sleep deprivation or mental fatigue in some cases

These benefits come from creatine's role in rapidly regenerating ATP via the ATP-PC energy system, which fuels short, intense bursts of effort like weightlifting, sprinting, or HIIT training.

How Does Creatine Work?

Creatine is synthesised naturally in the liver, kidneys, and pancreas from the amino acids arginine, glycine, and methionine. It's stored primarily in skeletal muscle as phosphocreatine, where it plays a key role in regenerating ATP.

During intense activity, ATP is quickly depleted. Creatine helps recycle ADP back into ATP, improving energy availability in the muscle. This supports strength output and workload capacity during repeated high-intensity efforts.

Types of Creatine & Which One Is Best for You

Creatine monohydrate is the most researched and widely used form. It's a go-to for strength and high-intensity training, and usually the most cost-effective option.

Other types include:

• Micronised creatine: finer particles for easier mixing
• Creatine HCl (hydrochloride): more water soluble, often preferred by those who find powders heavy
• Buffered creatine (Kre-Alkalyn): designed to resist breakdown in the stomach
• Creatine blends: combine multiple creatine types, sometimes with added ingredients

What About Flavoured Creatine?

Unflavoured creatine is a popular choice for stacking into protein shakes or pre-workouts, but flavoured creatine has become a growing trend. It's the same core ingredient, just in flavours like grape, tropical fruit, or berry, making it easy to enjoy with water alone.

Flavoured creatine is worth considering if you:

• Prefer drinking creatine on its own rather than mixing it into another shake
• Want a more enjoyable taste while keeping your routine simple
• Like variety in your supplement routine

At Nutrition Warehouse you'll find both classic unflavoured powders and flavoured options such as Micronized Creatine by Optimum Nutrition and R1 Charged Creatine by Rule 1 Proteins.

Is Creatine Beneficial for Women?

Yes. Creatine is used by both men and women and can be a useful option for active women who train regularly. Research suggests it may support training capacity, strength, and recovery when paired with a suitable program.

A common misconception is that creatine makes women "bulky." In reality, it's often used to support training output, which can support lean muscle development when paired with the right training and nutrition. More on this in our blog on Creatine Use in Women and Water Weight.

When Should You Take Creatine?

Creatine is commonly taken daily, not just on training days. A typical dose is 3-5g per day, with or without a loading phase (20g daily for 5-7 days).

• After training: may support recovery and help maintain consistent daily intake
• Before training: may support high-intensity performance during the session
• Consistent daily use: helps maintain creatine stores in muscle over time

A 2017 position stand from the ISSN notes that consistency matters more than timing. For practical tips, read Improve Your Results with Creatine.

Is Creatine Safe?

Creatine has been studied for decades and is widely recognised as safe for healthy individuals when taken within recommended doses. Research indicates it doesn't negatively affect kidney function in healthy users, and it isn't linked to dehydration or muscle cramps as once believed.

Creatine can increase water retention in muscle cells, so staying well hydrated is important.
