Promotes healthy sleep patterns. Supports the body's natural sleep-wake cycle. Improves sleep onset and quality. Promotes recovery after shift work and international travel. Delicious natural spearmint flavor. Melatonin Spray provides melatonin to help control the body's natural sleep cycle. Melatonin is a hormone that is normally released at night from the pineal gland. Research demonstrates that supplementation with melatonin significantly improves sleep onset, total sleep time and sleep quality when compared to placebo treatments. Supplementation with melatonin before sleeping has been shown to improve sleep quality and duration among shift workers, who often experience less sleep than daytime workers. Melatonin intake at local sleep times can also support the sleep-wake cycle after international travel. As melatonin levels significantly decrease with age, its supplementation can help promote healthy sleep patterns in older individuals.
