About this study

This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States.

Eligible participants will (1) have the opportunity for meaningful improvement (at least 30%) in their primary health outcome and (2) express acceptance in taking a product and not knowing its formulation until the end of the study.

Participants that report a known cardiac dysfunction, liver or kidney disease may be excluded. Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded.

Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded. Self-reported data are collected electronically from eligible participants for 7 weeks.

Participant reports of health indicators will be collected at 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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Participants must meet all the following criteria:

  • Adults, at least 21 years of age at the time of electronic consent, inclusive of all ethnicities, races, and gender identities
  • Assigned sex at birth will determine sex-specific recruitment and surveys (male vs female) employed, when needed

  • Reports being a heavy drinker (defined as drinking 3 or more alcoholic beverages per day)
  • Unable to read and understand English
  • Reports a current and/or recent (up to 3 months ago) major illness and/or surgery that poses a known, significant safety risk.
  • Reports a diagnosis of cardiac dysfunction, liver or kidney disease that presents a known contraindication and/or a significant safety risk with any of the study product ingredients.
  • NYHA Class III or IV congestive heart failure, atrial fibrillation, uncontrolled arrhythmias, cirrhosis, end-stage liver disease, stage 3b or 4 chronic kidney disease, or kidney failure
  • Reports taking medications that have a well-established moderate or severe interaction, posing a substantial safety risk with any of the study product ingredients.

Primary outcomes

  1. Change in Cognitive Function

    Time frame: 7 weeks

    Change in cognitive function: Difference in rates of change over time in cognitive function score as assessed by PROMIS Cognitive Function 8A (scale 8-40; where lower scores correspond to worse cognitive function)

Secondary outcomes

  1. Change in Fatigue

    Time frame: 7 weeks

    Difference in rates of change over time in fatigue score as assessed by Patient Reported Outcome Measurement System (PROMIS) Fatigue 8A (scale 8-40; where higher scores correspond to more severe fatigue)

  2. Change in sleep-related impairment

    Time frame: 7 weeks

    Difference between rates of change over time in sleep score as assessed by PROMIS Sleep-Related Impairment 8a (scale 8-40; where the higher scores correspond to worse sleep)

  3. Change in feelings of anxiety

    Time frame: 7 weeks

    Difference between rates of change over time in feelings of anxiety score as assessed by PROMIS Anxiety 8A (scale 8-40; with higher scores corresponding to more severe anxiety)

  4. Minimal clinically important difference (MCID) in fatigue

    Time frame: 7 weeks

    Likelihood of experiencing minimal clinically important difference in fatigue score as assessed by PROMIS Fatigue 8A (scale 8-40; where higher scores correspond to more severe fatigue)

  5. Minimal clinically important difference (MCID) in sleep

    Time frame: 7 weeks

    Likelihood of experiencing minimal clinically important difference in sleep score, as measured by PROMIS Sleep-Related Impairment 8a (scale 8-40; where the higher scores correspond to worse sleep)

  6. Minimal clinically important difference (MCID) in feelings of anxiety

    Time frame: 7 weeks

    Likelihood of experiencing minimal clinically important difference in feelings of anxiety score as assessed by PROMIS Anxiety 8A (scale 8-40; with higher scores corresponding to more severe anxiety)
