The effects of chronic resveratrol supplementation have yet to be investigated in healthy humans. It is hypothesised that the effects will be different to those seen in acute supplementation. This study will look specifically at cognitive performance, cerebral blood flow, subjective sleep, mood and health, blood pressure and plasma levels of resveratrol. It is hypothesized that these measures will be affected differently by acute and chronic supplementation.

Primary Outcome Measures:
  • Chronic Modulation of Cerebral Blood Flow [ Time Frame: 40- 80 minutes post- dose on day 28 of supplementation ] [ Designated as safety issue: No ]
    Cerebral blood flow (CBF) was measured in the frontal cortex with Near-Infrared Spectroscopy (NIRS). Modulation was deemed to have taken place if levels differed significantly from day 1 to day 28.

Secondary Outcome Measures:
  • Number of Participants With Modulated Mood [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Subjective mood was assessed with the Profile of mood states (POMS) questionnaire every 7 days during the 28- day period. Participants were deemed to have significant modulation of mood if their scores on week 1, week 2, week 3 and/or week 4 differed significantly from scores on the baseline questionnaire completed on day 1.

  • Number of Participants With Modulated Cognitive Performance [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Cognitive performance was assessed by a range of cognitively demanding tasks on day 28 of the supplementation period. Participants were deemed to have significant modulation of cognitive performance if their scores on these tasks were significantly different from scores taken on day 1.

  • Number of Participants With Significant Modulation of Sleep [ Time Frame: Day 28 ] [ Designated as safety issue: No ]
    Subjective perception of sleep quality was assessed with the PSQI. Participants were deemed to have significant modulation of sleep if scores on Week 1, Week 2, Week 3 and/or Week 4 differed significantly from those on day 1 (baseline).

  • Number of Participants With Significant Modulation of Health [ Time Frame: Day 28 ] [ Designated as safety issue: No ]
    Subjective perceptions of health were assessed with the General Health Questionnaire. Participants were deemed to have significant modulation of health if scores on Week 1, Week 2, Week 3 and/or Week 4 differed significantly from day 1 (baseline) completion.

  • Number of Participants With Significant Modulation of Blood Pressure [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Participants were deemed to have significant modulation of blood pressure if their readings on day 28 differed significantly from that taken on day 1 (baseline).

  • Number of Participants With Significant Modulation of CBF in MCA [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    CBF was assessed in the middle cerebral artery (MCA) with Trans-cranial doppler via a trans- temporal acoustic window. Participants were deemed to have significant modulation of CBF in the MCA if readings differed significantly from those obtained on day 1 (baseline).
