Rhodiola rosea L. Extract May Reduce Anxiety
Anxiety affects thousands of Americans and makes it harder for them to accomplish many daily tasks. A recent study suggests that taking a daily dose of Rhodiola rosea L. extract may improve mood in people with mild anxiety.
Participants in the study included 81 mildly anxious students with an average age of 21. They were given either two 200 mg doses of Rhodiola rosea L. extract daily or no treatment for 14 days. At the conclusion of the study, the researchers found that the supplement group had a significant reduction in self-reported measures of anxiety and stress as well as a reduction in secondary endpoints such as anger, confusion, and depression. They did not note any changes in cognitive function.
The safety and tolerability of the supplements were favorable.
Researchers from the University of Surrey conducted the study. It was published online ahead of print on October 27, 2015, in Phytotherapy Research.
Previous studies suggest that Rhodiola rosea L. extract may help increase energy and stamina, improve sexual function, irregular heartbeat, and lower high cholesterol levels. It has been used in folk medicines in the arctic regions of Europe and Asia for centuries. The best way to consume Rhodiola rosea L. is as an extract.
