What Does Research Say About Rhodiola Rosea?
Researchers have investigated specific Rhodiola extracts in relation to fatigue, attention and mental performance under demanding conditions, including overnight work, academic examinations and mentally challenging activities.2–4
These studies help explain scientific interest in Rhodiola.
What Is SHR-5?
SHR-5 is a standardized Rhodiola rosea extract used in the human studies below. Standardization allows researchers to investigate a preparation with specified characteristics.
Night Duty · 56 Healthy Physicians
Mental Performance During Demanding Work
A double-blind crossover study investigated SHR-5 in 56 healthy physicians working night shifts. During the first two-week study period, researchers reported favorable results in a combined measure of mental performance.2
Individual results may vary.
Academic Examinations · Placebo-Controlled Pilot Study
Fatigue During a Demanding Academic Period
Researchers studied SHR-5 in students during a 20-day examination period. Compared with placebo, the study reported favorable findings in some fatigue-related and well-being measures, although not every test showed a significant difference.3
Individual results may vary.
Mental Work · 161 Young Cadets
Mental Work Capacity Under Challenging Conditions
A randomized, double-blind study compared two single doses of SHR-5 with placebo and a separate untreated control group in 161 young cadets. Both dose groups performed better than placebo on a combined measure of mental work capacity. Researchers did not find a significant difference between the two doses.4
Individual results may vary.
What Does the Overall Research Tell Us?
Some human studies offer preliminary evidence of effects on mental performance and fatigue-related outcomes under demanding conditions.
The takeaway: These findings explain scientific interest in Rhodiola, but they do not establish benefits for Lost Empire Herbs’ finished extract or predict an individual’s results.
