The Claim
Creatine supplementation combined with resistance training results in a very small increase in muscle hypertrophy, with an average effect size of 0.11 standardized units (95% credible interval: −0.02 to 0.25), based on direct imaging measures across 10 randomized controlled trials involving healthy adults; this effect is too small to be practically meaningful for most individuals despite statistical probability of benefit.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking creatine while doing resistance training leads to a very small increase in muscle growth, averaging 0.11 standardized units, which is not meaningful for most people.

Creatine supplementation combined with resistance training likely results in a very small increase in muscle hypertrophy, with an average effect size of 0.11 standardized units (95% credible interval: −0.02 to 0.25), based on direct imaging measures across 10 randomized controlled trials involving healthy adults; this effect is too small to be practically meaningful for most individuals despite statistical probability of benefit.
Taking creatine lets muscles make more energy quickly during hard workouts, allowing people to lift heavier or do more reps. This extra work puts more stress on muscle fibers, which triggers the body to build more muscle protein and add small amounts of muscle mass over time.
What the research says
1 studyTaking creatine with weight training might make your muscles a tiny bit bigger, but only for some people—and even then, the change is so small you probably won’t notice it.
