Rhodiola rosea is an herb with a long history of use for helping the body to adapt to the stressors of life. Rhodiola has been listed in the national pharmacopoeias of France, Sweden, Denmark, and Russia as an adaptogen and overall “brain tonic”. Adaptogens support the body’s ability to handle stress by balancing the levels of hormones and neurotransmitters normally associated with the stress response. Rhodiola is unique among adaptogens in that it has been clinically shown to increase energy reserves and reduce levels of the stress hormone, cortisol. Rhodiola has been found to improve mental performance during night-shift duty, helping reduce fatigue in shift workers as well as the average person suffering from general fatigue.

Rhodiola is the ideal herbal product for those who frequently experience stress, especially those who respond to stressors with a feeling of helplessness. It is especially helpful for shift workers or those with high-stress lifestyles.

AOR Advantage

AOR’s Rhodiola is standardized for levels of both rosavin and salidroside to match the extracts used in the best clinical studies, offering superior efficacy compared to products that only standardize for one or the other.




Rhodiola is a powerful adaptogen which helps support focus, cognitive function, mental and physical stamina and helps relieve symptoms of mental fatigue related to stress. It has been traditionally used in Siberia for adaptation to the harsh climates on the tundra of north-central Asia.


AOR™ guarantees that all ingredients have been declared on the label. Contains no wheat, gluten, corn, nuts, peanuts, sesame seeds, sulphites, mustard, soy, dairy, eggs, fish, shellfish or any animal by-product.

Adult Dosage

Take two capsule daily on an empty stomach, not immediately before bedtime, or as directed by a qualified health care practitioner.


Do not use if you have bipolar spectrum disorder. Consult a healthcare practitioner if you are pregnant, breastfeeding, if you are taking antidepressant medication, hormone replacement therapy (HRT) or birth control pills, if symptoms persist or worsen, or for use beyond six weeks. May cause irritability and insomnia, in which case, discontinue use.

Anti-Fatigue Effects

One clinical trial found that in burn-out patients suffering from fatigue, Rhodiola reduced their cortisol (the stress hormone) levels upon awakening and improved their mental concentration, a capacity that is affected during burn-out.


Rat studies have also found that Rhodiola rosea could block the growth of tumors, decrease metastasis, and extend survival times. It also enhanced the effects of the antitumor drug cyclophosphamide.

Physical Endurance

Soviet scientists discovered a generation ago that Rhodiola allows experimental animals to use their body’s glycogen energy reserves more sparingly under forced exercise, and to replenish those reserves (and reserves of the crucial high-energy compound creatine phosphate) more quickly afterwards. These properties doubtless contribute to Rhodiola’s ability to extend animals’ endurance during forced swimming or clinging to a rod to avoid falling. To make sure that Rhodiola’s effects on physical performance was an adaptogenic effect, and not caused by flooding the body with steroids, scientists looked for the kind of hyper-masculinization you see in steroid freaks at the gym: no such signs were found.


Accordingly, Rhodiola extracts improve the organism’s capacity to stand up against a wide variety of stressors, including heat shock, heavy metal exposure, free radical assault, high altitude, liver-damaging chemicals, and exhaustive exercise. When eggs from freshwater snails were incubated with Rhodiola rosea, they had a survival rate of 90% when exposed to heat shock, compared to only 9% for eggs that were not exposed to Rhodiola.

Heart Stress

Another example is Rhodiola’s ability to protect the heart from stress. When lab animals are subjected to extreme cold or to massive doses of the stress hormone adrenaline, the regular, controlled beating of their hearts is disrupted and the oxygen supply is temporarily cut off. But Rhodiola supplements prevent arrhythmia, reduce the damage to the muscle cells of the heart, and balance the overflow of stress neurotransmitters normally associated with these stressors.

Cognitive Stress

Studies suggest that Rhodiola can help prevent symptoms associated with intense physical or mental strain such as a decline in work performance, sleep difficulties, poor appetite, irritability, hypertension, headaches and fatigue. In rats, Rhodiola rosea was found to benefit learning and memory. In a human clinical trial, a Rhodiola rosea extract along with a combination of vitamins and minerals was given to 120 adults with physical and cognitive deficiencies in a 12 week drug monitoring study. There was a significant improvement in these deficiencies, with observed improvements in symptoms such as exhaustion, decreased motivation, daytime sleepiness, sleep disturbances, concentration deficiencies, forgetfulness, susceptibility to stress and irritability. This is likely due to Rhodiola’s ability to influence the levels of several neurotransmitters in the brain.

Neurotransmitter Modulation

Animal studies have given us some clues to the neurochemical basis of these effects: Rhodiola has well-documented effects on the metabolism of a variety of neurotransmitters. For instance, Rhodiola enhances the transport of the serotonin precursors tryptophan and 5-hydroxytryptophan (5-HTP) across the blood-brain barrier, and decreases the action of the serotonin-degrading catechol-O-methyltransferase (COMT) enzyme. It also boosts brain levels of dopamine, acetylcholine, and norepinephrine, all of which are key neurotransmitters targeted by major classes of antidepressant drugs. Rhodiola also appears to influence the synthesis, levels, and/or activity of endorphins and enkephalins, since blocking the receptors for some of these “feel-good” peptides negates some of Rhodiola’s effects.

The Importance of Full Standardization

Earlier research identified salidroside (and its free form, p-tyrosol) as a key active ingredient in Rhodiola, and many clinical trials still use salidroside as the sole active for standardization of their Rhodiola botanicals. More recently, studies have focused on the effects of rosavin. Some Rhodiola species found in China and elsewhere contain salidroside but not rosavin, the most characteristic active ingredient of true Rhodiola rosea. On the other hand, many products fail to standardize for the salidroside content, despite the extensive documentation of its adaptogenic effects. A properly-standardized Rhodiola extract will contain at least 3% rosavins and 1% salidroside; p-tyrosol will also be present in small amounts.
