Effects of Rhodiola Rosea Supplementation on Mental Fatigue, Visuo-cognitive Processing, and Strength Performance

One of the most practical and accessible options for mitigating the occurrence of mental fatigue is the strategic use of nutritional supplements. Several nutritional supplements have been shown to reduce behavioural or subjective markers of mental fatigue, including caffeine, creatine, panax ginseng, and various vitamins or minerals. Among these, Rhodiola Rosea (RR), a supplement with purported adaptogenic and ergogenic properties, has gained attention. Several randomized controlled trials have reported reductions in mental fatigue after RR supplementation without adverse effects. The main objective of this study was to explore the effects of four days of Golden Root Extract (RR) supplementation on mental fatigue, visuo-cognitive processing, strength performance, and perceived exertion in young, healthy individuals.
