Brief summary

This is a randomised, double-blind, placebo-controlled study investigating the effects of the herb ashwagandha on cognition, sleep, and energy in children with parent-reported concerns in attention, memory, and concentration. In this 8-week, multi-national study comprising a total of 80 participants (40 participants recruited in Australia and 40 in India) participants will take two gummies a day containing 150mg 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 parent-report questionnaires that assess children’s mood, cognitive/executive function, fatigue, and sleep. It is hypothesised that, compared to the placebo, ashwagandha supplementation will be associated with greater improvements in cognitive function, sleep and energy levels.

Interventions

Ashwagandha extract (KSM-66) (1 gummy taken orally, twice daily with breakfast and dinner, delivering 300 mg a day for 8 weeks) Adherence to gummy intake will be monitored through a mobile phone app and gummy return and count.
