A favorite adaptogen of Russian athletes and workers for decreasing fatigue, increasing alertness, and improving memory. It is primarily sourced to Siberia, but different species of rhodiola grow worldwide (including the Appalachian mountains).
Though it is mildly stimulating, natural sleep is restored in the face of stress. Rhodiola offers anti-depressant properties, providing a different option than St. John’s wort (known for interactions with medications).
Rhodiola enhances cardiovascular function and immune function and protects nerve and brain tissue. Traditionally, rhodiola was used to improve work tolerance at high altitudes, and research suggests that it may increase oxygen delivery to tissues, especially the heart.
Rhodiola also offers significant immunomodulating properties.
Suggested Dosage: 100-200 mg of standardized extract (2-3% rosavins, 0.8-1% salidroside) twice daily.
Side effects: For some people, the herb is mildly stimulating. In general, however, rhodiola is well tolerated.
