Study summary

A randomized, double-blind, placebo controlled direct-to-consumer study assessing the impact of health and wellness products on stress and related health outcomes

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. Change in perceived stress

    Difference between rates of change over time in Perceived Stress score as assessed by NIH Toolbox Perceived Stress Survey (scale 10-50; where the higher scores correspond to worse perceived stress)

    Time frame: 7 weeks

  2. Minimal clinical importance difference (MCID) in perceived stress

    Likelihood of achieving a MCID in perceived stress, as measured by NIH Toolbox Perceived Stress Survey (scale 10-50; where the higher scores correspond to worse perceived stress)

    Time frame: 7 weeks

Secondary outcomes

  1. Change in feelings of anxiety

    Difference between rates of change over time in feelings of anxiety score as assessed by PROMIS Anxiety 4A (scale 4-20; where the higher scores correspond to worse feelings of anxiety)

    Time frame: 7 weeks

  2. Change in mood

    Difference between rates of change over time in mood score as assessed by PROMIS Depression 4A (scale 4-20; where the higher scores correspond to worse mood)

    Time frame: 7 weeks

  3. Change in cognitive function

    Difference between rates of change over time in mood score as assessed by PROMIS Cognitive Function 4A (scale 4-20; where the higher scores correspond to better cognitive function)

    Time frame: 7 weeks

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

    Likelihood of achieving a MCID in cognitive function, as measured by PROMIS Cognitive Function 4A (scale 4-20; where the higher scores correspond to better cognitive function)

    Time frame: 7 weeks

  5. Minimal clinical importance difference (MCID) in feelings of anxiety

    Likelihood of achieving a MCID in feelings of anxiety, as measured by PROMIS Anxiety 4A (scale 4-20; where the higher scores correspond to worse feelings of anxiety)

    Time frame: 7 weeks

  6. Minimal clinical importance difference (MCID) in mood

    Likelihood of achieving a MCID in mood, as measured by PROMIS Depression 4A (scale 4-20; where the higher scores correspond to worse mood)

    Time frame: 7 weeks

Other outcomes

  1. Change in sleep disturbance

    Difference between rates of change over time in sleep disturbance score as assessed by PROMIS Sleep Disturbance 4A (scale 4-20; where the higher scores correspond to worse sleep disturbance)

    Time frame: 7 weeks

  2. Minimal clinical importance difference (MCID) in sleep disturbance

    Likelihood of achieving a MCID in sleep disturbance, as measured by PROMIS Sleep Disturbance 4A (scale 4-20; where the higher scores correspond to worse sleep disturbance)
