Overview
This decentralized, single-arm study evaluates the effects of 90 days of daily Neuralli Mood supplementation on perceived stress, sleep disturbance, mood, anxiety, depressive symptoms, happiness, and occupational burnout in adults experiencing stress or occasional sleep disruption. Participants serve as their own controls, completing validated self-report measures before beginning supplementation and again after the 90-day intervention, with safety and adherence check-ins during the study.
Description
Neuralli Mood is a probiotic and postbiotic dietary supplement containing the proprietary gut-brain strains L. plantarum PS128 and heat-treated L. paracasei PS23. Participants take two capsules once daily, with or without food, at a consistent time for 90 days. Each two-capsule daily dose contains 30 billion CFU of L. plantarum PS128 and 20 billion heat-treated cells of L. paracasei PS23.
The study uses a prospective, open-label, single-group, within-participant design. Participants complete baseline assessments before the first dose and repeat the primary and secondary outcome assessments at the end of the 90-day supplementation period. Scheduled check-ins are used to assess adherence, tolerability, and adverse events.
The study is exploratory and is intended to generate preliminary evidence and individualized before-and-after information. Results will be interpreted in light of the absence of a concurrent control group, participant self-selection, expectation effects, and reliance on self-reported outcomes.
