Scientific background
Independent researchCreatine monohydrate
Creatine is a compound the body makes from the amino acids arginine, glycine and methionine, and it is also eaten in meat and fish. Most of it is stored in skeletal muscle, where phosphocreatine helps regenerate ATP, the immediate energy source for short, intense muscle contractions1.
Creatine monohydrate is the form used in most of the published research12.
Research evidence
Independent researchCreatine monohydrate
Supplementation raises muscle creatine stores. The International Society of Sports Nutrition position stand concludes that creatine monohydrate is an effective ergogenic supplement for increasing high-intensity exercise capacity and lean body mass during training1.
A meta-analysis of randomised trials found improved upper-limb strength when creatine was combined with resistance training3, and a meta-analysis in older adults found greater gains in muscle mass and strength with creatine plus resistance training than with training alone4.
In the EU, the European Food Safety Authority (EFSA) assessed the evidence and found a cause-and-effect relationship between a daily intake of 3 g of creatine and increased physical performance in successive bursts of short-term, high-intensity exercise5. That claim is authorised under Regulation (EU) No 432/20126, and a second claim on muscle strength in adults over 55 who do resistance training under Regulation (EU) 2017/6727.

Safety & potential risks
- Do not exceed the recommended daily dose.
- Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
- Keep out of the reach of young children.
Creatine monohydrate
Reviews of the clinical literature report no consistent adverse effects of creatine monohydrate in healthy people at commonly studied intakes. A meta-analysis found no significant effect on markers of kidney function82.
People with kidney disease, and anyone taking medication, should speak to a doctor before using creatine. A small rise in blood creatinine is expected with supplementation and can be misread as reduced kidney function2.
Regulatory status
Sold as a food supplement. No health claims are made for this product.
