What the science says

Creatine supplementation, particularly when combined with resistance training, consistently and significantly enhances both upper and lower body muscle strength. This effect has been demonstrated across various populations, though benefits may be more pronounced in males and adults under 50 years of age.

Full analysis

The claim is strongly supported by multiple systematic reviews and meta-analyses, which represent the highest level of evidence. These studies consistently demonstrate that creatine supplementation, particularly when combined with resistance training, leads to significant improvements in muscle strength. While benefits are observed across various groups, some evidence suggests greater gains in males and adults under 50, with specific benefits also noted for pre- and post-menopausal women. The evidence base is robust, indicating creatine as an effective ergogenic aid for strength enhancement.
