What is Rhodiola rosea extract?
Rhodiola rosea extract (Salidroside, Rosavin) is extracted from Rhodiola crenulata, which is a perennial flowering plant in the family Crassulaceae. It grows in cold regions of the world, including much of the Arctic, the mountains of Central Asia, scattered in eastern North America from Baffin Island to the mountains of North Carolina, and mountainous parts of Europe, such as the Alps, Pyrenees, and Carpathian Mountains, Scandinavia, Iceland, Great Britain and Ireland. It grows on sea cliffs and on mountains at altitudes up to 2280 meters. Several shoots grow from the same thick root. Shoots may reach 5 to 35 cm in height. R. rosea is dioecious – having separate female and male plants.
The aerial portion of rhodiola rosea is consumed as food in some parts of the world, sometimes added to salads. In Russia and Scandinavia, R. rosea has been used for centuries to cope with the cold Siberian climate and stressful life. The plant has been used in traditional Chinese medicine. The medicine can be used to prevent altitude sickness.

Salidroside and Rosavin are extracted from rhodiola crenulata and rhodiola rosea.

Salidroside may be more active than rosavin, even though many commercially marketed Rhodiola rosea extracts are standardised for rosavin content rather than salidroside.
