Sleep Well Observation Study

Insomnia is characterized by the recurring difficulty to fall or remain asleep despite motivation and means to do so. People with insomnia also experience excessive daytime sleepiness and other cognitive impairments while they are awake. Facing the situation mentioned and realizing that especially early preventive measures are needed to fight the increasing costs for treatment of sleep related diseases, effective nutrients might be a good and safe option to improve sleep quality.This single-arm, open-label, prospective, observational exploratory pilot study aims at collecting first data on efficacy and safety of "Sleep Well".
