Top picks by evidence
- Low evidence3 studies
Across 3 studies, 2 reported beneficial effects (1 moderate, 1 small) and 1 reported a neutral effect on reducing perceived exertion with Rhodiola supplementation. The evidence is preliminary but suggests a small-to-moderate beneficial effect, primarily observed in athletes (e.g., male collegiate soccer players) with a studied dose of 2.4 g/day over 28 days.
Dose: 2.4 g·day⁻¹ - Low evidence3 studies
Across 3 randomized controlled trials, all reported neutral small-sized effects of beta-alanine on rating of perceived exertion (RPE) in athletic populations. The most-studied dose was 6.4 g/day, and the median study duration was 18 days. No study observed a statistically significant reduction in RPE.
