Evidence-Based Benefits

  • Reduces stress-related fatigue by 20% in a multicenter RCT with 161 participants using 370mg/day of SHR-5 extract standardized to 3% rosavins and 1% salidroside
  • Improves cognitive function, including short-term memory and associative thinking during stressful conditions as shown in the same study
  • Supports stress adaptation by regulating reactive oxygen species (ROS) and heat shock proteins (HSPs)
  • May help regulate cortisol levels to support hormonal balance through adaptogenic mechanisms
  • Enhances mood by reducing fatigue and improving mental clarity under stress

What the Research Says

Rhodiola Rosea has been studied in several randomized controlled trials (RCTs) and smaller clinical studies, with a growing body of evidence supporting its use for managing stress-related fatigue and enhancing cognitive performance. Research typically uses extracts standardized to 3% rosavins and 1% salidroside, with doses ranging from 200-600mg daily. A notable multicenter RCT (n=161) demonstrated significant reductions in fatigue and improvements in memory and associative thinking during stressful conditions compared to placebo. While more research is needed for long-term effects and broader applications, the existing evidence suggests moderate efficacy for stress-related fatigue and cognitive support under acute stress.
