Outcome Measures

Primary Outcomes (1)

  • Change in the Visual Analog Scale as Compared to Baseline Compared Across Two Conditions

    VAS uses a 10-cm scale for participants to indicate the extent to which each of them feel happy or sad. The change in VAS before versus after sad mood induction is the change score in VAS. The change score on the day with active dietary supplement is compared to the change score on the day with the placebo dietary supplement.

    Two sessions at least one week apart

Secondary Outcomes (2)

  • Potential Side Effects Questionnaire

    Twice on both test days: once in the morning right before the morning active or placebo dietary supplement and once more right after the observed break

  • Profile of Mood States

    Anytime during initial assessment visit. On both test days, at least 1 week apart at: (7:35-8:00); (8:40-9:05); (11:20-11:45); (12:25-12:50); (13:10-13:30); (14:30-14:55)
