Ranked by research evidence. Compare 7 supplements across 10 papers from the biomedical literature, with effect direction, evidence strength, and dose range for each.
Top picks by evidence
- Low evidence3 studies
Across 3 studies, 1 reported a small beneficial effect on reduced perceived exertion, while 2 found neutral (small) effects, resulting in mixed findings overall. The only beneficial study was a 28-day RCT in 48 male volleyball athletes using Rhodiola combined with caffeine, which showed significantly lower RPE scores. The median study duration was 16 days, and the limited evidence base precludes a firm conclusion.
