Rhodiola appears to significantly reduce the effects of prolonged and minor physical exhaustion that results in fatigue. This is more related to ‘burnout’ effect and stress, or prolonged but low intensity physical exercise. There is limited evidence that physical exercise can be improved with rhodiola, but this appears to be limited to untrained persons. Despite this, rhodiola appears to be reliable in reducing fatigue symptoms and improving symptoms of stress (and consequently, well-being) in persons fatigued from non-exercise related stressors.
Rhodiola can improve cognitive functioning in persons who experience a reduction in fatigue, but there is insufficient evidence to support an outright increase in cognition (which should occur in non-fatigued persons) and not enough studies have assessed cognitive decline for conclusions to be made.
Other studies suggest that it is highly neuroprotective against toxins (requires more evidence) and that comsumption of rhodiola or its active component can reduce stress-induced binge eating (although this was only tested with female rats). In the brain, rhodiola appears to increase serotonin.
Rhodiola may promote longevity, with preliminary (non-mammalian) evidence suggesting up to a 20% increase in lifespan secondary to mechanisms that are independent of caloric restriction. Although promising, mammalian evidence is needed to confirm.[1]
Our vegan Rhodiola (rhodiola rosea) contains 500mg of the adaptogenic herb in each pill. The supplement is standardized at 3% rosavin and 1% salidroside – the extracts responsible for Rhodiola’s adaptogenic properties.

The decrease in fatigue appears to be quite strong and somewhat reliable when a low dose is given over a prolonged period of time or a high dose is given acutely; there is one study which has noted an increase in fatigue (relative to placebo) that needs to be expanded upon.[2]
Research Score: Very Strong
In a 2015 study, patients graded "mildly anxious" were given 400 mg of Rhodiola daily for 14 days. The patients all showed reductions in symptoms related to anxiety, anger, confusion, and depression and showed a significant improvement in overall mood.[3] Rhodiola also increases contentment in fatigued or stressed people to a greater extent than other supplements.[4]
Research Score: Strong
A 2015 study on marathon runners indicated Rhodiola can prevent infections caused by exercise by inhibiting viruses from multiplying.[8]
Research Score: Promising
One study indicated higher doses of Rhodiola can halve the severity of symptoms of depression.[9] While these results are promising, further investigation is also needed.
Research Score: Promising
