Bottom line. Creatine: the recorded evidence reports no meaningful benefit for heart health. See the source and population limits. [1 RCT]

Direction
null
Magnitude
Meta-analysis of 8 RCTs: creatine supplementation showed no statistically significant effect on total cholesterol, LDL, HDL, or triglycerides versus control. Certainty of evidence was rated very low to low due to methodological limitations in the included trials.
