Abstract

Abstract : 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.
