Overview

Rhodiola rosea is a nootropic herb of the adaptogen class. An adaptogen is a substance which promotes homestasis, a restorative process that returns the body and brain to it’s optimal functioning. Like other adaptogens, it is characterized by conferring a wide range of benefits to both mental and physical health. It’s primary benefit appears to be reducing fatigue, and does so quite effectively.1www.ncbi.nlm.nih.gov/pubmed/152566902www.ncbi.nlm.nih.gov/pubmed/108392093www.ncbi.nlm.nih.gov/pubmed/127255614www.ncbi.nlm.nih.gov/pubmed/19170145 5www.plosone.org/article/info:doi/10.1371/journal.pone.01084166www.ncbi.nlm.nih.gov/pubmed/222286177www.ncbi.nlm.nih.gov/pubmed/210365788www.ncbi.nlm.nih.gov/pubmed/11081987

Rhodiola has also been shown to have strong nootropic effects, with improvements in cognition and memory being the most significant.2www.ncbi.nlm.nih.gov/pubmed/108392093www.ncbi.nlm.nih.gov/pubmed/127255616www.ncbi.nlm.nih.gov/pubmed/222286178www.ncbi.nlm.nih.gov/pubmed/1108198714link.springer.com/article/10.2478%2Fs11536-012-0124-7 15www.ncbi.nlm.nih.gov/pubmed/375162316www.ncbi.nlm.nih.gov/pubmed/309559917www.ncbi.nlm.nih.gov/pubmed/23396166

It also demonstrates potent neuroprotective and antioxidant effects.18www.springerlink.com/content/m1324p7h35u44607/19www.ncbi.nlm.nih.gov/pubmed/2061544420www.ncbi.nlm.nih.gov/pubmed/1955442521www.ncbi.nlm.nih.gov/pubmed/22095090 One of the active compounds, salidroside, has even been shown to cause neurogenesis when injected.12www.ncbi.nlm.nih.gov/pubmed/2335845013www.sciencedirect.com/science/article/pii/S0895398809600623

Rhodiola also confers benefits to general mental health. It improves mood,2www.ncbi.nlm.nih.gov/pubmed/108392093www.ncbi.nlm.nih.gov/pubmed/127255616www.ncbi.nlm.nih.gov/pubmed/222286179www.ncbi.nlm.nih.gov/pubmed/17990195 reduces stress,6www.ncbi.nlm.nih.gov/pubmed/22228617 reduces depressive symptoms,9www.ncbi.nlm.nih.gov/pubmed/179901952223www.ncbi.nlm.nih.gov/pubmed/17072830 significantly reduces anxiety, especially generalized anxiety disorder.22www.ncbi.nlm.nih.gov/pubmed/1830739023www.ncbi.nlm.nih.gov/pubmed/1707283024www.ncbi.nlm.nih.gov/pubmed/922529722www.ncbi.nlm.nih.gov/pubmed/18307390

The mechanism of action behind rhodiolas mood-brightening effects appear to come from the inhibition of an enzyme called monoamine oxidase.10www.ncbi.nlm.nih.gov/pubmed/1916812311www.thieme-connect.com/products/ejournals/abstract/10.1055/s-0028-1084200 Monoamine oxidase is the enzyme responsible for breaking down dopamine, norepinephrine, and serotonin in the brain. By inhibiting the enzymes ability to break down these neurotransmitters, a relative increase will occur.

Overall, Rhodiola appears to be great for improving mood and reducing fatigue, and appears to be a reliable cognitive enhancer. As a result of these qualities, rhodiolia one of the most popular and best natural nootropics out there.

 

 

Where to Purchase Rhodiola Rosea

Rhodiola Rosea may be purchased at Nootropics Depot.

I recommend Nootropics Depot because they have been around for a long time and have maintained a solid reputation. They have excellent quality control metrics: they  do in-house testing as well as independent 3rd-party testing, and they have certificates of analysis available for all of their products.

 

 

Dosage Information

Rhodiola rosea is best taken as an extract that contain 3% rosavins and 1% salidroside, the most common of which is the SHR-5 extract.

There is a bell-curve response with doses, and so the less-is-more rule strongly applies here. Doses range from 100-680mg, and should not exceed 680mg in one day or it may lose effectiveness. Rhodiola rosea does not need to be taken with meals.
