Sleep Fast Nighttime Spray is marketed as a highly potent support against insomnia and other sleeping disorders. The formula is one of the dietary supplements offered by Tranquility Labs. This is an American manufacturer that seems to be recognized for its dedication the delivering high standard supplements (it is a BBB certified business). Unfortunately, the company’s official site does not provide information about the year of establishment, company background or its history so far.

This formulation is promoted as a complementary product to the Tranquilene day formula. These two supplements are currently the only formulations offered by the manufacturer. The formula is claimed to be helpful in a number of sleep related problems weather they are occasional or of chronic nature. Sleep Fast Nighttime Spray is suitable for individuals who suffer from nighttime waking, have problems falling asleep because of daily worries, or want to overcome a jet lag. All in all, this formula should help consumers to enjoy a full night sleep without the morning grogginess and prevent the daytime tiredness that results from such sleeping disturbances.

Unlike Tranquilene, Sleep Fast Nighttime Spray does not benefit of a very detailed description. The main active ingredients are indicated, but not described in terms of benefits. However, these ingredients are very popular substances and information regarding their benefits is available on numerous other sites and medical publications

Sleep Fast Nighttime Spray Ingredients

Sleep Fast Nighttime Spray contains the following ingredients: Vitamin C, Vitamin B6, Chromium, Melatonin, proprietary blend (Valerian root, extract 4;1, Chamomile flower extract 4:1, Griffonia simplicifolia (5-HTP), lemon balm leaf extract), purified water, natural flavors, citric acid, Potassium Sorbate, Sodium Citrate, and Sucralose.

Product Features

Sleep Fast Nighttime Spray includes several active chemicals, including Melatonin. This is a naturally occurring substance in humans, classified as a hormone. This substance has been attributed with numerous beneficial properties, including in cancer prevention and protecting the immune system. This chemical is also responsible for the regulation of the sleep-awake sleeping cycles. It is produced by the pineal gland in the brain, which is inactive during the day. During nighttime, in the absence of light, this gland starts producing Melatonin which is further released into the blood. Melatonin acts as a sedative and helps the body to relax and become less alert preparing the individual for its nighttime sleep. Melatonin production is inhibited by light. Daytime levels of melatonin are almost undetectable. Melatonin levels also decrease by age, which is why elder people have more trouble sleeping than children and young adults.

Melatonin deficiency is one of the common causes of sleeping problems. Numerous supplements that offer supplements based on this substance promise to restore its levels, but the doses of active substance are sometimes much higher than those naturally produced by healthy adults. It is believed that supplemental doses of 1 to 3 mg may result in increased levels of Melatonin of up to 20 times more than normal values. This is why many physicians recommend supplements that contain lower doses (0.3-1 mg 90 minutes before bedtime). Improper dosages may result in unwanted side effects like increased fatigue, or depression symptoms. More so, some studies involving melatonin supplements did not show any improvement in the sleeping patterns of the subjects as compared to placebo.

The Chamomile flower extract is another commonly recommended herbal remedy against sleeping problems. It is mainly used as a tea, and has been recommended for centuries as a sleep aid and relaxing drink. The plant is also believed to possess good anti-inflammatory, antispasmodic, antifungal, and anti-allergenic properties. Its traditional uses include it in a broad spectrum of treatment for different health issues including asthma, stress relief, cold symptoms, colic in infants, insomnia, eye inflammation, mouth sores, skin problems, and many more. Chamomile based products are not recommended for pregnant women or those who suffer from allergies to plants (including daisy-like flowers).
Side effects of Sleep Fast Nighttime Spray are not indicated. The suggested dose is 6 sprays per day.
