To avoid reductions in total sleep time, coffee (107 mg per 250 mL) should be consumed at least 8.8 h prior to bedtime and a standard serve of pre-workout supplement (217.5 mg) should be consumed at least 13.2 h prior to bedtime. The results of the present study provide evidence-based guidance for the appropriate consumption of caffeine to mitigate the deleterious effects on sleep.

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.
