Rhodiola (Rhodiola rosea) is a plant that grows in cold, mountainous regions. One of the active elements is rosavin.
Function
Rhodiola is a nerve stimulator capable of combating asthenia (chronicfatigue). De Bock (2004) found an improvement in endurance performance in athletes supplemented with rosavin. In De Bock’s study, however, no improvement whatsoever was noted in strength and psychomotor performance.
Negative notes
De Bock’s results are not replicated by other authors, who also fail to confirm its efficacy with regard to endurance performance (e.g. Colson, 2005). No adverse effects of rhodiola are known.
Form and posology
Rhodiola supplements are mostly available on the market in tablet form. No particular dosage specifications are known.
