Assessment schedule on Days 1 and 56. Both ICa and NIRS data-collection started with a 10 min pre-dose recording period, the last five minutes of which was used as the baseline measurement. NIRS data was then collected continuously throughout. Following consumption of the day’s treatment participants sat quietly for 60 minutes, with data from the last five minutes of this period used as the ICa resting measurement. Participants then completed the control task, and the five cognitive tasks, in counterbalanced order, with a two minute resting period between each five minute task period
