Details and patient eligibility


The goal of this clinical trial is to study the impact of VL-NL-02 in improving sleep quality, restorative sleep complaints, quality of life, stress levels, and sleep stages. 48 participants are expected to be randomized in a ratio of 1:1 to receive either VL-NL-02 or placebo and will be assigned a unique randomization code. Each group will have at least 20 completed participants after accounting for a dropout/withdrawal rate of 17%. The intervention duration for all the study participants is 21 days. Participants will be asked to fill multiple questionnaires to assess sleep quality and mood imbalance.
