Effects of Creatine Supplementation and Resistance Training on Muscle Strength Gains in Adults <50 Years of Age: A Systematic Review and Meta-Analysis
Nutrients (2024) · Meta analysis · n=509
In comparison with a placebo, creatine supplementation combined with resistance training significantly increased upper-body (WMD = 4.43 kg, p < 0.001) and lower-body strength (WMD = 11.35 kg, p < 0.001).

Additionally, certain in vitro experiments have indicated that exogenous D-ribose exposure could trigger apoptosis in specific cell lines.
The 5 g point is a crossover trial in 123 adults taking 5 g a day for 6 weeks (PMID 37968687): the effect on backward digit span only bordered significance (p = 0.064), reasoning (Raven's matrices) did not change, and side effects were 4.25 times more common than on placebo. The 20 g point is a one-week trial of 5 g four times a day in 32 older adults, where most memory tasks improved (PMID 17828627). A meta-analysis of 10 trials found a small memory benefit (SMD 0.29), mostly in adults aged 66 to 76, with no effect of dose across 2.2 to 20 g a day (PMID 35984306), so the curve is flat. The two trials differ in age and length as well as dose. No minimum or optimal dose is established.
