Genestra - Melatonin Spray - 30 Millilitre(s) - NPN: 80029769 -- Melatonin Spray provides melatonin to help reset the bodys sleep-wake cycle. Difficulty falling and staying asleep are two major symptoms of sleep dissatisfaction in Canada, which affects over 20% of Canadians. Research demonstrates that supplementation with melatonin significantly decreases the time required to fall asleep, increases total sleep time, and improves sleep quality when compared to placebo treatments.Supplementation with melatonin before sleeping can improve sleep quality and duration among shift workers, who often experience sleepiness and/or judgment errors during work, leading to poor job performance. Melatonin intake at local sleep times can also advance the sleep-wake cycle to decrease fatigue associated with jet lag. Melatonin levels significantly decrease with age, which may contribute, in part, to sleep dissatisfaction among older individuals.
