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).
The points come from one crossover dose-response trial in 10 healthy men given 70, 140 or 280 mL of concentrated beetroot juice, containing 4.2, 8.4 and 16.8 mmol of nitrate (about 260, 521 and 1,042 mg), 2.5 hours before cycling (PMID 23640589). 70 mL did not change the exercise responses compared with nitrate-depleted placebo. 140 and 280 mL extended time to task failure in severe cycling by 14% and 12%, and the higher dose gave no further improvement, so the curve is flat above 521 mg. The abstract does not report tolerability, so no ceiling is set. The curve rests on acute single doses in young men and cannot show effects of daily use, in women, in older adults or in trained athletes.
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.
AI-estimated from published studies. Interpret as directional guidance.
Creatine has a higher evidence score (9.5/10 vs 7.5/10) and wins in 2 of 3 categories.
Both Beetroot and Creatine score equally (90) for athletic performance.
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
