Have you ever wondered how some people seem to have endless energy for intense workouts, or recover remarkably quickly? While genetics and training certainly play a huge role, there’s a powerful natural compound within our bodies that’s a major player in energy production and muscle function: creatine.

Often associated with bodybuilders and athletes, creatine is far more fundamental than just a supplement. So, let’s dive into what it is, why our bodies rely on it, and how we can ensure that we’re getting enough…
What Is Creatine?
At its core, creatine is a nitrogenous organic acid that’s naturally produced in our bodies, primarily in the liver, kidneys and pancreas, from three amino acids: arginine, glycine, and methionine. The vast majority of our creatine stores, around 95%, are found in our skeletal muscles, with smaller amounts in the brain and testes.
Its primary role? Energy! We can think of creatine as a rapid-fire energy reserve, particularly for short bursts of high-intensity activity.
Why Do We Need Creatine? The Science of Energy
Our muscles use a molecule called adenosine triphosphate (ATP) for energy. When a muscle contracts, ATP is broken down into ADP adenosine diphosphate, releasing energy. However, our natural stores of ATP are very limited, so this is where creatine swoops in.
Creatine helps to regenerate ATP through a process involving phosphocreatine. Phosphocreatine donates a phosphate group to ADP, rapidly converting it back into ATP. This means:
- More Power for Short Bursts: Imagine lifting heavy weights, sprinting, or jumping. These activities demand immediate, explosive energy. Creatine ensures a readily available supply of ATP, allowing you to perform more reps, run faster, or jump higher.
- Improved Performance: By sustaining ATP levels, creatine can help delay fatigue during intense exercise, leading to improved overall performance in activities requiring strength and power.
- Faster Recovery: While its primary role is during activity, some research suggests creatine may also play a role in muscle recovery by reducing muscle cell damage and inflammation after strenuous exercise.
- Potential Brain Benefits: Beyond muscles, creatine is also found in the brain. Some studies are exploring its potential role in cognitive function, memory, and even protecting against neurological diseases.

Since creatine is primarily found in animal products, those following vegetarian or vegan diets will have lower baseline creatine levels and so dietary supplements are particularly beneficial to increase natural creatine stores.
Creatine is a vital compound that fuels our high-intensity movements and plays a crucial role in overall physical performance. It supports our body’s natural energy systems and unlocks new levels of strength and power. Whether you’re an athlete, a fitness enthusiast, or simply looking to optimise your wellbeing, understanding creatine is a step towards a stronger, more energetic you.
Free Soul Creatine Monohydrate Powder
A creatine supplement that I love is the Free Soul Creatine Monohydrate Powder which provides 3.4g of creatine per serving. With no additives or fillers, this vegan friendly micronised powder contains a two month supply in each 204g pouch.
Clean and unflavoured, I simply mix it into a glass of water each morning to provide me with strength, assist in recovery and boost my cognitive performance. Expertly curated with women in mind, it’s also third-party tested. Supporting muscle function, energy production and mental clarity at any time of day is always a bonus.
As the micronised formula dissolves easily, you can also blend it into a smoothie or mix it into your pre-workout before the gym to help you to train smart and recover strong. It’s the perfect way to start every day, whether I’m lifting weights, running rings around my children or simply showing up at my very best.
