What Is Creatine and How Does It Work?
Creatine is a compound your body already produces, synthesised from three amino acids - arginine, glycine, and methionine - in your liver, kidneys, and pancreas. While roughly 95% is stored in your skeletal muscle, small amounts are also held in your brain and heart. Your body produces about 1–2g per day, but for active individuals, this is rarely enough to fully saturate your muscle stores.
Everything comes back to ATP (adenosine triphosphate), the primary energy your cells run on. During high-intensity efforts like heavy lifting or sprints, your muscles burn through ATP almost instantly. Once depleted, your body turns to stored phosphocreatine to rapidly regenerate that energy. Supplementing with True Protein Creatine Mono increases that phosphocreatine pool, providing more ATP on demand for more reps and power. Think of it as a reserve fuel tank for when you need peak output most.
Where Does Creatine Come From in Food?
If you eat meat regularly, you are getting some dietary creatine, but usually not enough to fully top up your stores.
| Food |
Creatine per 100g |
| Herring |
6.5–10g |
| Pork |
5g |
| Beef |
4.5g |
| Salmon |
4.5g |
| Tuna |
4g |
| Chicken |
3.4g |
| Rabbit |
3.4g |
For those following a vegan or vegetarian diet, baseline muscle creatine levels can be 20–30% lower than those of omnivores, making supplementation a high-impact addition to your routine.

What Does the Evidence Actually Show?
The research on creatine is exceptionally strong, supporting its use for both physical and mental performance.

Supporting Strength, Muscle Growth, and Recovery
Meta-analyses show that creatine produces significantly greater strength gains compared to training alone - roughly 8% more on average. It supports hypertrophy through increased training volume, enhanced satellite cell activity, and greater water retention inside the muscle cell. This intramuscular water makes muscles look fuller and perform better, rather than causing subcutaneous bloating. By reducing inflammation and muscle damage markers, creatine also helps you bounce back faster for your next session.
Can Creatine Benefit Brain Function and Ageing?
Your brain runs on ATP too. Creatine stores in brain tissue support cognitive performance, especially under sleep deprivation or mental fatigue. Studies show improved memory and reasoning with supplementation, making it as relevant for your mind as your muscles. For those over 40, creatine combined with resistance training genuinely counters age-related muscle loss (sarcopenia). Emerging research also points to benefits for bone mineral density and mood regulation.
Is Creatine Beneficial for Women?
Creatine is not just a supplement for men. Women stand to benefit just as much - and in some life stages, even more. It will not make you "bulky" as it does not change your hormones. During perimenopause and menopause, when oestrogen decline accelerates muscle loss, creatine supplementation helps support lean mass, strength, bone density, and mood stability. It is one of the most underutilised tools for women navigating hormonal change.
Which Form of Creatine Should You Use?
The answer is simple: Creatine Monohydrate. It is the gold standard - the most researched, effective, and affordable option available.

Do You Need to Load Creatine?
Loading (20g/day for 5–7 days) gets you to full saturation faster, but both routes end up in the same place. For most people, taking 3–5g daily without loading is simpler and equally effective; it just takes a few extra weeks to kick in fully.

Consistency matters far more than timing. Take it when it fits your routine and you will actually remember to do it.
Is Creatine Safe and What Are the Myths?
Yes, creatine is safe. Long-term use at recommended doses has no adverse effects on kidney function, liver health, or hydration in healthy individuals. Common side effects are minor, such as initial intramuscular water weight or mild GI discomfort at high loading doses.

| You need to cycle |

Who Benefits Most?
-
Older Adults (40+): Helps maintain muscle mass and functional strength.
-
Vegans and Vegetarians: Often see the largest relative gains due to lower baseline muscle stores.
-
Endurance Athletes: Benefits from improved glycogen loading and faster recovery.
-
Tested Athletes: Legal across all competitive sports and WADA-compliant.
-
Non-Responders: Around 25–30% of people see minimal response, often because their stores are already saturated from a high red meat diet.
