Summary
Brief summary
In this randomised, double-blind, placebo-controlled study, 90 adults aged 40 to 80 years with self-reported memory problems will be randomly assigned to receive tocotrienols (TheraPrimE rice) or a placebo for 12 weeks. Changes in cognitive performance will be assessed at baseline and week 12 by administering the Test of Memory and Learning (TOMAL-2) and Behavior Rating Inventory of Executive Function–Adult Version (BRIEF-A). Moreover, a self-report questionnaire assessing sleep quality will be administered monthly to assess changes in sleep quality. Changes in blood concentrations of several markers associated with inflammation, neuroplasticity, oxidative stress/ antioxidant activity, and blood lipids will also be measured to help identify the mechanisms of action associated with tocotrienol supplementation.
