NCT04706494

Brief Summary

AlphaWave® L-theanine will be compared against placebo to evaluate how the investigational study product effects on salivary cortisol, EEG readings, blood pressure, and heart rate in a moderately stressed and otherwise healthy adult population. It is hypothesized that participants taking the AlphaWave® L-theanine will have reduced stress levels as assessed by the parameters stated. Participants will be consuming the investigational study product or placebo in the clinic only.

  • Females of child-bearing potential must have a negative baseline urine pregnancy test and agree to use a medically approved method of birth control for the duration of the study. All hormonal birth control must have been in use for a minimum of three months. Acceptable methods of birth control include:

  • Double-barrier method
  • Intrauterine devices
  • Non-heterosexual lifestyle or agrees to use contraception if planning on changing to heterosexual partner(s)
  • Vasectomy of partner at least 6 months prior to screening
  • Individuals with moderate stress as determined by the Perceived Stress Scale (scores ranging from 14 - 26 are considered moderate stress)
  • Have a regular sleep-wake cycle with a bedtime between 9:00 pm and 12:00 am and receive between 7 and 9 hours of sleep for at least 3 weeks prior to baseline
  • Agrees to maintain current sleep schedule throughout study
  • Agrees to maintain current levels of diet, supplements, and exercise until the end of the study
  • Agrees to refrain from exercising 24-hours prior to the visits
  • Agrees to abstain from using hair products on the day of visits
  • +2 more criteria

You may not qualify if:

  • Women who are pregnant, breastfeeding, or planning to become pregnant during the course of the trial
  • Clinically significant abnormal laboratory results at screening as assessed by the QI
  • Participants who have a known allergy to the test material's active or inactive ingredients
  • Current employment that calls for rotating shift work or shift work that will disrupt normal circadian rhythm or have worked shift work in the last 3 weeks
  • Travelled across 1 or more time zones in the last 3 weeks and/or is anticipating more travel
  • Self reported epilepsy and/or seizures
  • Type I or Type II Diabetes
  • Unstable metabolic disease or chronic diseases as assessed by the QI
  • Current or history of any significant disease of the gastrointestinal tract
  • Hypertension treated with medication or supplements or untreated hypertension
  • Self reported anxiety or depression
  • Significant cardiovascular event in the past 6 months as assessed by the QI
  • Major surgery in the past 3 months or individuals who have planned surgery during the course of the trial. Participants with minor surgery will be considered on a case-by-case basis by the QI
  • Individuals with an autoimmune disease or are immune-compromised
