Investigating the Efficacy of Rest-ZZZ Formula in Healthy Participants With Difficulty Falling Asleep or Staying a Sleep

A randomized, double-blind, placebo-controlled, cross-over pilot study to investigate the efficacy of Rest-ZZZ in healthy participants with difficulty falling asleep or staying a sleep. The study will have 3 study periods. During each study period, eligible participants will consume either Rest-ZZZ, comparator product, or placebo for 7 days during each study period (1 product per study period), with a 1-week washout period in between each period. The primary objective is the comparison in sleep quality using a sleep quality questionnaire from pre-supplement to Day 7 between the Rest-ZZZ, comparator, and placebo. Other study outcomes include the change in quality of life, profile of mood states (POMS), and safety outcomes such as vital signs, clinical chemistry and hematological markers
