Creatine supplementation does not induce renal damage

Objectives:
Creatine supplements are intended to improve performance, but there are indications that it can overwhelm liver and kidney functions, reduce the quality of life and increase mortality. Therefore, this review article has been conducted.

Does creatine supplementation increase risk of renal damage?

Study design:
This review article included 15 studies in the qualitative analysis and 6 studies in the quantitative analysis.

Results and conclusions:
The investigators found creatine supplementation did not significantly increase serum creatinine levels [standardized mean difference = 0.48, 95% CI = 0.24-0.73, p = 0.001, I2 = 22%].

The investigators found creatine supplementation did not significantly increase plasma urea values [standardized mean difference = 1.10, 95% CI = 0.34-1.85, p = 0.004, I2 = 28%].
The investigators concluded that creatine supplementation does not induce renal damage in the studied amounts and durations.
