This is a Randomized, Open-label, 4-arm Pilot Study Designed to Evaluate the Efficacy and Tolerability of Four Qualia Sleep Formulations (Formulas A, B, C, and D) in Healthy Adults Aged 18 Years and Older Who Report Poor Sleep Quality. The Investigational Products Are Encapsulated Dietary Supplement

The primary aim of this open-label, four-arm pilot study is to evaluate the efficacy of four Qualia Sleep formulations (A, B, C, and D) in improving sleep quality and satisfaction over 28 days in adults reporting sleep disturbances, as assessed by the PROMIS Sleep Disturbance - Short Form 8b (PROMIS-SD). The primary objective is to determine the change from baseline to day 28 in PROMIS-SD scores across all participants using each formulation. Secondary objectives are to: (1) assess changes in PROMIS-SD in a subgroup with more pronounced baseline sleep disturbance; (2) evaluate changes in sleep-related daytime impairment using the PROMIS Sleep-Related Impairment Short Form 8a (PROMIS-SRI) in both the overall sample and the higher-disturbance subgroup; (3) examine changes in somatic and cognitive pre-sleep arousal as measured by the Pre-Sleep Arousal Scale (PSAS) in both the overall sample and the higher-disturbance subgroup; and (4) characterize the safety and tolerability profile of each formulation over the 28-day supplementation period. Participants take 2 capsules once daily at night, 30-60 minutes before bed, for 28 consecutive days. Participants complete regular check-in surveys on days 1, 3, 7, 14, 21, and 28. All study data will be collected electronically using secure survey links completed remotely on participants' own devices.
