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) be aged 35-60, (2) actively participant in non-professional aerobic activities 2 or more times a week, (3) have the opportunity for meaningful improvement (at least 30%) in their primary health outcome, (4) experience a decrease in sports performance due to tiredness, and (5) express acceptance in taking a product and not knowing its formulation until the end of the study. Participants that report a known contraindication or with wellestablished, 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 5 weeks. Participant reports of health indicators will be collected at enrollment and throughout the active period of study product usage. 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.

3.1 Inclusion

Participants must meet all the following criteria:

  • Adults, aged 35-60 at the time of electronic consent, inclusive of all ethnicities, races, and gender identities
  • Assigned sex at birth will determine sex-specific recruitment and PROs (male vs female) employed, when needed
  • Experiencing fatigue and/or perceiving a decline in sports performance due to tiredness
  • Resides in the United States
  • Has the opportunity for at least 30% improvement in their primary health outcome
  • Expresses a willingness to take a study product and not know the product identity (active or placebo) until the end of the study

3.2 Exclusion

Individuals who report any of the following during screening may be excluded from participation:

  • Report being pregnant, trying to become pregnant, or breastfeeding
  • Unable to provide a valid US shipping address and mobile phone number
  • Reports current enrollment in another clinical trial
  • Reports being a heavy drinker (defined as drinking 3 or more alcoholic beverages per day)
  • Unable to read and understand English at a 7th grade level
  • 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.
  • Anticoagulants, antihypertensives, anxiolytics, antidepressants, chemotherapy, immunotherapy, sedative hypnotics, seizure medications, medications that warn against grapefruit consumption, corticosteroids at doses greater than 5 mg per day, diabetic medications, oral anti-infectives (antibiotics, antifungals, antivirals) to treat an acute infection, antipsychotics, MAOIs, or thyroid products
  • 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 and/or pose a safety risk
  • Lack of reliable daily access to the internet
  • Participants residing in the states of New York, New Jersey, or Rhode Island are eligible to enroll in the main study and will complete all primary study activities. However, these participants are not eligible to participate in the biomarker collection. This restriction is due to state regulatory requirements governing direct-to-consumer at-home laboratory specimen collection and processing that cannot be accommodated within the fully decentralized design of the collection. No alternative collection pathway is available under the current protocol.
  • To ensure compliance, state-of-residence logic is built into the enrollment platform. Participants who indicate a residential address in New York, New Jersey, or Rhode Island will not be presented with the biomarker collection consent or any associated study materials. This automated screening ensures that ineligible participants are not inadvertently enrolled in the collection. These participants will otherwise proceed through full main study enrollment and participation without interruption.

Treatment and study plan

Placebo Health Performance Control

Dietary Supplement

Participants will use their Placebo Health Performance Control as directed for a period of 4 weeks

Active Health Performance Product

Dietary Supplement

Participants will use their Active Health Performance Product as directed for a period of 4 weeks

Primary outcomes

  1. Change in fatigue

    Time frame: 5 weeks

    Fatigue score as assessed by Patient Reported Outcome Measurement System (PROMIS) Fatigue 8A (scale 8-40; where higher scores correspond to more severe fatigue)

Secondary outcomes

  1. Change in sleep

    Time frame: 5 weeks

    Sleep score as assessed by PROMIS Sleep Disturbance 8A (scale 8-40; where higher scores correspond to higher levels of sleep disturbance)

  2. Change in feelings of stress

    Time frame: 5 weeks

    Stress score as assessed Perceived Stress Scale 4 (PSS-4) (scale 0-16; where lower scores correspond to less stress)

Other outcomes

  1. Minimal clinically important difference (MCID) in fatigue

    Time frame: 5 weeks

    Minimal clinically important difference (MCID) in fatigue: 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)

  2. Minimal clinically important difference (MCID) in sleep

    Time frame: 5 weeks

    Minimal clinically important difference (MCID) in sleep: Likelihood of experiencing minimal clinically important difference in sleep score as assessed by PROMIS Sleep Disturbance 8A (scale 8-40; where higher scores correspond to higher levels of sleep disturbance)

  3. Minimal clinically important difference (MCID) in feelings of stress

    Time frame: 5 weeks

    Minimal clinically important difference (MCID) in feelings of stress: Likelihood of experiencing minimal clinically important difference in feelings of stress as assessed by Perceived Stress Scale (PSS-4) (scale 0-16; where lower scores correspond to less stress)
