Rhodiola Rosea is an adaptogen that has been used in traditional medicine for thousands of years. Adaptogens are natural herbs that can help the body adapt to physical and chemical stress as well as resist it. Animal studies show that Rhodiola can increase serotonin, which may reduce symptoms of depression and increase overall mood.
Several studies show that Rhodiola Rosea can slightly improve mental performance, including memory. The improvement in memory may depend on the reduction of mental fatigue and stress. This combination of mental stimulation and stress reduction may lead to memory improvement.
Athletes may also use Rhodiola Rosea to boost their physical capacity. Several studies show that the work capacity increases while the recovery time between the workouts decreases.
Research shows the minimum daily dose of Rhodiola Rosea is 100 mg and the maximum dosage is 600 mg. However, the dosage depends on an individual’s age, weight and sensitivity. Most people should start with the smallest dose and increase it slowly to approximately 500 mg.
Mode of Action
Animal studies suggest that Rhodiola Rosea works by helping boost the amount of serotonin in the brain. Serotonin is responsible for many functions, including pain perception and behavior. Additionally, it is theorized that the adaptogens work by helping the cells manufacture cell fuel faster and more efficiently. However, no specific studies currently exist to confirm this theory.
Rhodiola has a very low degree of toxicity. In laboratory animals the LD50 for the extract was 28.6 (25.1-32.6) mg / kg. In human cell culture studies, the extract has been found to have a lower toxicity than vitamin C.
