The results of the meta-analysis suggest that creatine supplementation did not significantly alter serum creatinine levels (standardized mean difference = 0.48, 95% confidence interval 0.24-0.73, P = .001, I2 = 22%), and did not alter plasma urea values (standardized mean difference = 1.10, 95% confidence interval 0.34-1.85, P = .004, I2 = 28%). The findings indicate that creatine supplementation does not induce renal damage in the studied amounts and durations.

J Clin Endocrinol Metab, 2024 ↗“Metformin currently has enough data for me personally to feel comfortable not only taking it myself (and my wife), but also recommending it to my patients.”
