Somato® (Phytomelatonin) Versus Synthetic Melatonin and Placebo on Sleep Quality

2026年6月25日 更新者：Nutraland USA, Inc.

Sleep Solutions in Focus: A Randomized Comparison of Phytomelatonin (Somato®), Synthetic Melatonin, and Placebo

This study examines the effects of a plant-based phytomelatonin supplement compared to synthetic melatonin and placebo in adults with suboptimal sleep quality. The research uses a randomized, double-blind, placebo-controlled, three-arm clinical trial design. The primary aim is to determine whether phytomelatonin improves sleep outcomes compared to placebo and whether it matches or exceeds synthetic melatonin. Participants will be randomly assigned to receive 2 mg phytomelatonin, 10 mg synthetic melatonin, or an inactive placebo. Each participant will take one capsule nightly for 28 days. Objective sleep metrics will be captured continuously using the Oura Ring wearable device. Subjective outcomes will be measured at baseline and post-intervention using validated surveys such as the Pittsburgh Sleep Quality Index and the SF-36. Weekly visual analog scales will assess morning grogginess. Safety, tolerability, and user experience differences between groups will also be evaluated.

  • Pregnant or breastfeeding women will be excluded from the study.
  • Substance Use Disorder: Individuals with a history of drug or alcohol dependency who have not maintained sobriety for a minimum of the past 12 months.
  • Severe Medical Conditions: Presence of severe or unstable medical conditions that may interfere with study participation or outcomes.
  • Use of Mood-Affecting Medications: Use of any medications known to significantly influence mood, circadian rhythms, or melatonin pathways.
  • Sensitivity to Nightshades: Known sensitivity or allergy to nightshade plants, including tomatoes, due to the nature of the study intervention.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Change from Baseline Pittsburgh Sleep Quality Index (PSQI) Global Score at Day 28
大体时间：Baseline (Day 0) and Day 28
The PSQI is a self-administered questionnaire used to measure sleep quality and disturbances over a 1-month time interval. The questionnaire consists of 19 individual items, creating 7 component scores that are summed to yield one global score. The total score ranges from 0 to 21, where lower scores denote better sleep quality.
