Primary Outcome Measures :
  1. Choice reaction time as assessed by the Makoto Arena Device [ Time Frame: Change from baseline after 90 days of supplementation ]

Secondary Outcome Measures :
  1. Cognitive function (speed, reaction time, attention, executive function, memory, and motor speed) as assessed by a computerized test battery [ Time Frame: Change from baseline after 90 days of supplementation ]
  2. Subjective mood as assessed using a Likert scale questionnaire [ Time Frame: Change from baseline after 90 days of supplementation ]
  3. Subjective sleep quality and efficiency as assessed using Likert and visual analog scale questionnaires [ Time Frame: Change from baseline after 90 days of supplementation or between group comparisons at day 90. ]
