Rhodiola is an adaptogen that hails from Russia and Scandinavia and has been used traditionally for its anti-fatigue and endurance-boosting qualities. In general, rhodiola may support your body's ability to handle stress, fatigue, and symptoms of depression. We include rhodiola in Renewable Energy because it may protect against inflammation and muscle damage after exercise. Taking rhodiola may also be associated with improved endurance by lowering the heart rate and reducing perceived effort during exercise.
