What the research says

4 studies

  1. Study: Effect of <i>Eurycoma longifolia</i> water extract (Physta <sup>®</sup> ) on menopausal quality of life and mood states

    The study gave women Tongkat ali and asked about their mood. They felt a little better, but the improvement could have happened by chance, so we can't be sure it really helps.

  2. Study: Effect of Tongkat Ali on stress hormones and psychological mood state in moderately stressed subjects

    People who took Tongkat Ali for a month felt less tense and less angry, so it seems to help mood.
