Review: Rhodiola Rosea Root (Rosavin)

This is the third adaptogen that I am reviewing — I’m starting to suspect that adaptogen may indicate a herb that alters gut bacteria by reducing those that produce stress chemicals. There is no effective medical definition of adaptogen so inclusion is largely by popular allegation.  Tinospora cordifolia [Guduchi], Asparagus racemosus [ a species of asparagus], Emblica officinalis[ Indian gooseberry], Withania somnifera[Ashwagandha], Piper longum[Indian long pepper] and Terminalia chebula were deemed to be adaptogens in Adaptogenic properties of six rasayana herbs used in Ayurvedic medicine[1999]

Rhodiola Rosea has a short monogram available with several reviews finding contradictory results.

Dosage: ” indicating that the intake of 2 capsules after breakfast is more effective than the intake of 1 capsule after breakfast and 1 after lunch.”  Efficacy and tolerability of a Rhodiola rosea extract in adults with physical and cognitive deficiencies [2007] which also stated “statistically highly significant improvement  in physical and cognitive deficiencies” (in other words some improvement).  “Rhodiola extract at a dose of 200 mg twice daily for 4 weeks is safe and effective in improving life-stress symptoms to a clinically relevant degree” Therapeutic effects and safety of Rhodiola rosea extract WS® 1375 in subjects with life-stress symptoms–results of an open-label study.[2012]

Comment: While I have often used this, both Ashwagandha and Magnolia Bark seem to have significiant greater impact on me.
