Brief summary

In this randomised, double-blind, placebo-controlled study, 60 generally healthy adults aged 18 to 65 experiencing high stress will be randomly assigned to receive an ashwagandha extract (NRAHG001) or a placebo for 28 days. Changes in self-reported stress, mood and fatigue will be measured over time. Moreover, changes in the stress response using subjective and physiological measures after exposure to an experimental stress procedure (Socially Evaluated Cold-Pressor Test) will be investigated. The effects of ashwagandha supplementation on metabolomic markers will also be investigated to help understand the mechanism of action associated with ashwagandha supplementation. It is hypothesised that ashwagandha will be associated with a reduction in self-reported stress, and improvments in overall mood and fatigue.

Interventions

Ashwagandha extract (NRAHG001) (1 capsule taken orally, once daily in the morning with or without food, delivering 30mg for 4 weeks). Adherence to capsule intake will be measured by capsule return at day 7 and 28.
