What are the Health Benefits of Adaptogens?
A 2012 study conducted by the National Center for Biotechnological Information (NCBI) showed that consuming Rhodiola can help relieve stress by having a therapeutic effect on the mind and body.  As a part of the study, over 100 adults were given the adaptogen every day for 4 weeks.  Significant improvements in stress relief and increased mental clarity were observed out of this group after just 3 days. A 2009 study also conducted by NCBI concluded that the extract can significantly combat stress related fatigue.  The study was thoroughly conducted, with a double-blind and under a placebo-controlled setting. It was concluded that the adaptogen Rhodiola significantly had an anti-fatigue effect that increases mental performance as well as decreasing the cortisol response to awakening stress in patients with fatigue syndrome.
