Effects of Creatine on Strength and Power
Meta-analysis2025
A meta-analysis examining upper- and lower-body strength and power outcomes associated with creatine supplementation combined with resistance training.
- Resistance-trained adults
Backed by Science. Built for Strength, Power & Performance.
Creatine monohydrate is one of the most extensively studied ingredients in sports nutrition. Research supports its use for improving strength, power and performance during repeated bouts of brief, high-intensity activity. When combined with resistance training, it can also support increases in lean muscle mass.
Product benefits depend on consistent use, individual response and the recommended conditions of use.
The Evidence, Simplified
What the Research Means for You
You do not need to read hundreds of studies to understand why creatine has become one of the most widely used sports supplements. The strongest evidence can be summarized in three practical benefits.
Strength & Power
Creatine can improve strength, power and performance during repeated bouts of brief, high-intensity physical activity.
Lean Mass Support
When combined with resistance training, creatine can support increases in lean muscle mass.
Simple Daily Use
Creatine works through consistent daily use. A loading phase is not required when the product is taken as directed over time.
Ongoing Scientific Study
Areas of Emerging Research
Researchers continue to study creatine in areas beyond sports performance. These topics are presented for educational purposes and should not be interpreted as approved product claims or guaranteed outcomes.
Emerging Research
Cognition & Brain Health
Researchers are studying whether creatine may influence certain aspects of memory, attention and cognitive performance in specific populations.
Emerging Research
Healthy Aging
Research is exploring how creatine may support strength, function and physical resilience as people age.
Emerging Research
Recovery
Some studies are investigating creatine in relation to exercise recovery, muscle function and rehabilitation.
Emerging Research
Mood & Other Applications
Early research is examining possible relationships between creatine and additional areas of health. More evidence is needed before broad conclusions can be made.

Understanding the Evidence
How to Read Creatine Research
Not every study answers the same question. Results can vary depending on the participants, dosage, duration, exercise program and outcome being measured. Strong conclusions are usually based on multiple well-designed studies rather than a single paper.
Peer-Reviewed
The study was evaluated by other qualified experts before publication.
Study Population
Results in trained athletes, older adults or other specific groups may not apply equally to everyone.
Study Duration
Some effects require weeks of consistent use and may not be noticeable immediately.
Total Evidence
Systematic reviews and meta-analyses can provide stronger overall evidence than a single small study.
Science for the Life You Live
PURELii believes good science should be understandable, transparent and relevant to everyday people.
Safety & Responsible Use
A Strong Safety Profile
Creatine monohydrate is one of the most extensively studied sports supplement ingredients. It is generally well tolerated by healthy adults when used according to the product directions.
Some people may experience temporary digestive discomfort, particularly when taking large amounts at once. Taking the recommended serving with adequate fluid may help improve tolerance.
Consult a healthcare professional before use if you are pregnant or breastfeeding, have a medical condition, take medication or have been advised to restrict your intake of certain nutrients or supplements.
Always follow the directions, cautions and conditions of use printed on the Purelii product label.
