Evidence-backed FAQ

Does creatine help build muscle?

Direct answer

Creatine may add a modest increase in lean body mass when combined with resistance training. Meta-analyses report about 1 kg of additional lean mass on average versus training alone, while creatine without exercise did not significantly increase lean body mass.[1], [2]

What the evidence shows

The strongest evidence comes from pooled randomized trials in people participating in resistance training; the result is a group average, not an expected individual outcome.[1], [2]

Important limitations

Trials differed in population, dose, duration, and training design, and subgroup findings remain uncertain.[1], [2]
