Acute & Chronic Effects of Avena Sativa on Cognition & Stress

Status Completed

Clinical Trial Summary

Clinical Trial Description

The flavanoid and terpene phytochemicals present in wild green oat interact with multiple mechanisms relevant to brain function; including those which would modulate cognition and stress. The current study aims to test this in a group of N=128 males and females between the ages of 35-65yrs before and after 28 days supplementation of placebo, 300-, 600- and 900mg of a wild green oat extract. The study is randomized (within x3 age categories also; 35-45, 46-55, 56-65yrs), placebo controlled and counterballanced across parallel groups. Participants will first attend a training/screening session followed by x2 lab-based testing sessions, 28 days apart. In the lab-based sessions participants will complete baseline cognitive assessments; including whilst undergoing a stressful observed methodology (the observed multi-tasking stressor or 'OMS'). Here galvanic skin response and heart rate will be measured and before and after the OMS participants will provide a saliva sample which will be analysed for cortisol and alpha-amylase levels. This procedure will be repeated 120- and 240- minutes post-dose. Between the lab-based sessions participants will complete mood scales via a mobile phone application 'cognimapp'. ;
