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

  • 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 current use of the primary ingredient(s) and/or similar product(s) to the active study product(s) that may limit the effects of the study products
  • Been diagnosed with Gastric Ulcerations

    Difference in rates of change over time in pain collective score as assessed by a collective of PROMIS Pain Interference 6A, Neuropathic Pain 5A, Nociceptive Pain 5A, and Pain Intensity 1A (scale 16-90; with higher scores corresponding to greater pain)

Secondary outcomes

  1. Change in feelings of anxiety

    Time frame: 7 weeks

    Change in feelings of anxiety: Difference between rates of change over time as assessed by PROMIS Anxiety 4A (scale 4-20; with higher scores corresponding to more severe anxiety)

  2. Change in sleep

    Time frame: 7 weeks

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

  2. Minimal clinically important difference (MCID) in sleep

    Time frame: 7 weeks

    Minimal clinically important difference (MCID) in sleep: Likelihood of experiencing minimal clinically important difference in sleep score as assessed by PROMIS Sleep Disturbance 4A (scale 4-20; where higher scores correspond to higher levels of sleep disturbance)

  3. Change in Pain Intensity

    Time frame: 7 weeks

    Change in Pain Intensity: Difference in rates of change over time in pain intensity score as assessed by PROMIS Pain Intensity 3A (scale 0-10; with higher scores corresponding to more severe pain intensity)

  4. Change in nociceptive pain

    Time frame: 7 weeks

    Change in nociceptive pain: Difference in rates of change over time in nociceptive pain score as assessed by PROMIS Nociceptive Pain 5A (scale 5-25; with higher scores corresponding to greater nociceptive pain)

  5. Change in neuropathic pain

    Time frame: 7 weeks

    Change in neuropathic pain: Difference in rates of change over time in neuropathic pain score as assessed by PROMIS Neuropathic Pain 5A (scale 5-25; with higher scores corresponding to greater neuropathic pain)
