About this study

This is a randomized, blinded, placebo-controlled study conducted with adult participants, age 21 and older and residing in the United States.

Eligible participants will (1) endorse a desire for better concentration, (2) indicate an interest in taking a health and wellness product to potentially help their concentration, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study.

Participants with known liver or kidney disease, heavy drinkers, and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Those taking certain medications will be excluded.

Self-reported data are collected electronically from eligible participants over 7 weeks. Participant reports of health indicators will be collected during baseline, throughout the active period of study product use, and in a final survey. All study assessments will be electronic; there are no in-person visits or assessments for this real-world evidence study.

Primary outcomes

  1. Change in cognition (mental clarity)

    Time frame: 6 weeks

    Mean difference in cognition score as assessed by Patient Reported Outcome Measurement System (PROMIS) Cognitive Function Short Form 8A (scale 8-40; where the higher scores correspond to greater cognitive function)

Secondary outcomes

  1. Change in executive functioning

    Time frame: 6 weeks

    Mean difference in cognition score as assessed by Adult Executive Functioning Inventory (ADEXI) (scale 1-5; with higher scores corresponding to lower executive functioning)

  2. Change in sleep quality

    Time frame: 6 weeks

    Mean difference in sleep quality score as assessed by PROMIS Sleep Disturbance 4A (scale 4-20; with higher scores corresponding to greater sleep disturbance)

  3. Change in energy (fatigue)

    Time frame: 6 weeks

    Mean difference in energy score as assessed by PROMIS Fatigue 4A (scale 4-20; where higher scores correspond to more severe fatigue)

  4. Change in anxiety

    Time frame: 6 weeks

    Mean difference in anxiety score as assessed by PROMIS Anxiety 4A (scale 4-20; with higher scores corresponding to more severe anxiety)

  5. Change in mood (emotional distress)

    Time frame: 6 weeks

    Mean difference in mood score as assessed by PROMIS Depression 4A (scale 4-20; where higher scores correspond to more severe depression)

  6. Change in libido

    Time frame: 6 weeks

    Mean difference in libido score as assessed by PROMIS Sexual Interest 2.0 (scale 2-10; where higher scores correspond to greater sexual interest)

  7. Minimal clinical importance difference (MCID) in cognitive function

    Time frame: 6 weeks

    Likelihood of achieving a MCID in cognitive function, as measured by PROMIS Cognitive Function Short Form 8A (scale 8-40; where the higher scores correspond to greater cognitive function)
