Silent Night is an herbal formula that claims to relax the nervous system, promoting more restful, longer-lasting sleeping patterns. According to Nature's Way, its manufacturer, its effects kick in less than an hour of use, with its effects lasting through the night. Not surprisingly, its main ingredient is valerian, a relaxing herb purported to promote better sleeping patterns. Although Silent Night claims it can treat occasional sleeplessness, it has also suggested it could help treat the sleeping problems associated with insomnia, a sleeping disorder.
Silent Night contains vitamin C, calcium, and a proprietary blend of hops, valerian root and scullcap.
According to a few studies, only one of its key ingredients may help people fall asleep--but it doesn't help restore a person's natural sleeping patterns. According to a 2003 study conducted by the University of Sydney, valerian root can help significantly improve energy levels after sleep, but may not improve their overall sleep time or onset. A followup study also shows that valerian root may not work until at least 28 days of use. A study on hops also shows hops may cause drowsiness, making people more prone to sleep, but does little else to improve the quality of sleep. In fact, none of Silent Night's ingredients have been clinically proven to correct or restore a person's sleeping patterns or relax the nervous system, two claims guaranteed by this supplement.
Yes, although hops may cause some slight drowsiness. Its effects are not described as serious, however. Its ingredients may cause adverse effects if combined with sedatives, such as Xanax.
As a sleep aid, Silent Night may not be effective for short-term use. There is also no clinical evidence it can restore a person's sleeping patterns or relax the nervous system.
