Rhodiola rosea Root Extract

Rhodiola rosea is an adaptogenic herb with a long history of folk use in Russia, Scandinavia, Baltic countries, and Asia. Its traditional uses included being a tonic to help counter fatigue and enhance the capacity for mental and physical work performance. R. rosea grows in cold regions and in mountainous parts of Europe through Central Asia. This ability to adapt to extreme temperatures and environments may be part of the reason R. rosea was studied (and eventually categorized as an adaptogen) by Russian researchers. Decades of research support this adaptogenic categorization, with R. rosea supporting resistance to a variety of different types of stressors. R. rosea contains many biologically active substances; Its rosavins (rosavin, rosin, and rosarian) and salidroside are the major bioactive compounds for producing standardized extracts. Rhodiola rosea main uses are in helping with adaptation to physically and mentally fatiguing circumstances and supporting energy, alertness, concentration, mental stamina, and mood.*

RHODIOLA ROSEA FORMULATING PRINCIPLES AND RATIONALE

We consider Rhodiola rosea to be an herbal adaptogen, so expect it to follow hormetic dosing principles. Herbal adaptogens tend to have a hormetic zone (or range) where there’s a favorable biological response (see Qualia Dosing Principles) and don’t follow “more is better” formulating principles. This is consistent with the comparative studies on R. rosea root, where for example, an amount of 370 mg supported capacity for mental work, while a higher amount had similar (but not greater) benefits [1]. Standardized R. rosea root extracts have most commonly been used in human studies at servings ranging from 100 mg to 600 mg/day—a fairly broad range—however, the most common amount supplemented in studies has been between 225-400 mg. We use a serving within this narrower, more commonly supplemented range.*
