Rhodiola rosea has been extensively studied in Russia and Scandinavian countries for over 35 years and is categorized as an adaptogen because of its ability to increase resistance to chemical, biological, and physical stressors.
Rhodiola has been found to inhibit stress-induced depletion of important brain neurotransmitters. The adaptogenic properties of
Rhodiola are attributed primarily to this ability to influence the levels and activity of neurotransmitters and the amino acids that mimic the effect of opiates in the brain, such as the beta-endorphins. Because it is an adaptogen,
Rhodiola has the potential to normalize neurotransmitters in the central nervous system without causing drowsiness or fatigue. In other words, it helps maintain normal levels of brain chemicals but, when they are already normal,
Rhodiola will not further affect them.
Russian studies suggest a positive role for
Rhodiola in situations characterized by a decline in work performance, poor appetite, sleep disturbances, irritability, and fatigue. Studies have found improved mental performance in physicians on night duty who were supplemented with
Rhodiola. Medical students given
Rhodiola during exam periods reported improved concentration and performance, as well as enhanced well-being, improved sleep, and greater mood stability.
In addition to aiding sleep,
Rhodiola can enhance mood and decrease occasional episodes of worry and nervousness, allowing for more efficient functioning under stressful conditions.
