Rating (out of 5): 3
Rhodiola crenulata, closely related to Rhodiola rosea, has been traditionally used in Tibetan and Chinese medicine as an adaptogen to enhance physical and mental performance, including concentration. Recent scientific research has investigated its potential nootropic (cognitive-enhancing) effects. Several clinical studies and meta-analyses—mostly on Rhodiola rosea but with some data on R. crenulata—suggest that standardized extracts may help improve attention, reduce fatigue, and enhance cognitive function under stress. Proposed mechanisms include modulation of neurotransmitters such as serotonin and dopamine, as well as antioxidant and anti-inflammatory effects. For example, a randomized, double-blind, placebo-controlled study published in 2009 (Darbinyan et al., Phytomedicine) found improvements in attention and fatigue in subjects taking Rhodiola extract. However, most human studies are small, short-term, and often use mixed populations (healthy volunteers and those with stress or fatigue), and not all directly measure concentration as a primary outcome. There is also some extrapolation from studies on R. rosea to R. crenulata due to their similar phytochemistry. Overall, moderate scientific evidence supports the use of Rhodiola species—including R. crenulata—for improving concentration, especially in situations of fatigue or stress, but more rigorous and larger studies are needed.
