Efficacy
Statistical methods / analysis
Based on a previous study on ashwagandha, we are predicting an effect size of 0.6 compared to placebo. Based on this, a sample size of 36 per group is required. This gives an 80% chance of finding an effect at a statistical significance of 0.05. In this study, we will be recruiting 40 participants per group (80 participants in total). Forty participants will be recruited in Australia and 40 in India. Based on the 80 people recruited in Australia and India we have a suitable power to find an effect, even after dropouts.

Pre and post analyses will be conducted to determine changes in the following:

1. Computerised Mental Performance Assessment System (COMPASS)
2. Profile of Mood States, abbreviated version (POMS-A)
3. Mental Fatigue Scale (MFS)
4. Behavior Rating Inventory of Executive Function – Adult Version (BRIEF-A)

Summary
Brief summary
This is a randomised, double-blind, placebo-controlled, multi-national study investigating the effects of the herb ashwagandha on cognition, energy, and mood in adults presenting with self-reported cognitive complaints and low energy. In this 8-week, study comprising a total of 80 participants (40 participants recruited in Australia and 40 in India) participants will take two capsules a day containing 300mg of ashwagandha or placebo. We will assess changes in cognitive performance through the completion of a computer-based test that assesses various cognitive skills (e.g., attention, working memory, and episodic memory), and self-report questionnaires that assess, mood, cognitive/executive function, and fatigue. It is hypothesised that, compared to the placebo, ashwagandha supplementation will be associated with greater improvements in cognitive function, mood, and energy levels.
