While studies have been conducted on animals to determine the potential benefits and side effects of rhodiola, there have been few studies on humans. However, in studies conducted on humans, most are limited to short periods of time. Therefore, the long-term effects have not been studied thoroughly, and you may be safer limiting use of rhodiola to shorter periods of 6 to 12 weeks.Science suggests that its properties as an adaptogen and ability to affect choline levels in the brain make it beneficial to human cognitive performance. This trial evaluated the impact of a Rhodiola rosea L. extract on self-reported anxiety, stress, cognition, and other mood symptoms. Eighty mildly anxious participants were randomized into two different groups of either Rhodiola rosea L (2 × 200 mg dose Vitano®, 1 tablet taken before breakfast and 1tablet before lunch) or a control condition (no treatment). Self-report measures and cognitive tests were completed at four testing sessions over a period of 14 days. Relative to the controls, the experimental group demonstrated a significant reduction in self-reported, anxiety, stress, anger, confusion and depression at 14 days and a significant improvements in total mood. No relevant differences in cognitive performance between the groups were observed. Rhodiola rosea L (Vitano®) presented a favourable safety tolerability profile. Although this was a non-placebo controlled trial, it is unlikely that the findings were the result of placebo effects as changes appeared gradual and were specific to certain psychological measures. However, we cannot determine a causal relationship; further investigations are recommended to support the effects of Rhodiola rosea L. extract on stress related symptoms.
