Rhodiola is a plant that has been used medicinally for centuries. Since 1960, more than 180 modern pharmacological, phytochemical and clinical studies have been published.4 “Rhodiola has demonstrated a remarkable ability to enhance cellular energy metabolism. The studies published thus far show the herb to be highly beneficial for both physical and mental performance under stress. It provides significant enhancement of mental energy and eliminates fatigue. It stimulates norepinephrine, dopamine and serotonin and has cholinergic effects in the central nervous system. Rhodiola also supports and enhances the effects of these neurotransmitters by increasing the delivery of precursors (building blocks) that can be utilized to produce dopamine and serotonin.” 5
A randomized, double-blind and placebo-controlled trial studied the effect of Rhodiola on young, healthy physicians on night duty. The researchers measured rhodiola’s effect on five different meatures of mental acuity: associative thinking, short-term memory, calculation, concentration and speed of audiovisual perception. It was concluded that statistically significant improvements in all five of those mental performance parameters in the physicians who took Rhodiola rosea for two weeks. 6
