The Complete Alteril® Formulation
What makes the Alteril® nighttime capsule so effective is that it combines 4 of the best-known, medically proven natural sleep inducers and regulators into one effective nighttime capsule.
Plus it includes four more all-natural herbals that promote sleep, encourage relaxation, reduce nervous tension, alleviate anxiety, and more...
L-Tryptophan is an essential amino acid that's critical in the natural production of both serotonin and melatonin in your body, neurotransmitters that are necessary for regular sleep (melatonin helps regulate your body's circadian cycle, while serotonin communicates to your brain your need for sleep).
Along with relieving sleeplessness, L-Tryptophan can also reduce minor premenstrual symptoms, calm nervous irritability, relieve muscle pain from exercise, reduce your craving for carbohydrates, and support healthy mental function.
Melatonin is a hormone produced by the pineal gland, a small, light-sensitive organ in your brain. Its production is stimulated by darkness and suppressed by light, and it's understood to be key in helping your body know when it's time to sleep, and time to wake up (your circadian rhythm).
Melatonin supplements are used to help the blind, who lack the visual light/dark visual cues, maintain a normal sleep pattern. They may also help establish new sleep patterns, making them effective in preventing jet lag or adjusting to night shifts.
Melatonin occurs naturally in some foods, including oats, corn, rice, ginger, tomatoes, barley, and bananas.
L-Theanine is an amino acid found in tea leaves, and is responsible for giving green tea its distinctive taste.
L-Theanine is thought to play a major role in the reduction of stress and anxiety – two of the main causes of insomnia and other sleep disorders. People who consume L-Theanine show an increase in "Alpha" brain waves, which are weak electrical impulses that your brain produces when it's in a highly relaxed state.
As well as a powerful antidote to stress, L-Theanine is also considered to be useful for enhancing learning and concentration, for normalizing blood pressure, reducing cholesterol, boosting your immune system, easing the symptoms of PMS, and fighting cancer.
Valerian is a hardy perennial flowering plant native to Europe, South Africa, and parts of Asia. It has been used since the time of the ancient Greeks for treating liver problems, digestive illnesses, nausea, nervousness, and sleeplessness.
Valerian is known for its sedative properties, and is a popular natural choice for the treatment of insomnia, anxiety, and depression. Unlike prescription medications for the same conditions, valerian is not habit-forming, and does not leave you feeling groggy or "hung over" the next day.
Chamomile, a flowering plant belonging to the daisy family, contains an essential oil – called bisabolol – that has anti-irritant, anti-inflammatory, and anti-microbial properties. As such, chamomile is considered effective in the treatment of muscle spasms, burns and scrapes, and skin conditions such as psoriasis and eczema.
Beyond these properties, chamomile also contains glycine, an amino acid known to act as a nerve relaxant, making it a valuable tool in the fight against insomnia and other sleep disorders.
Since the 16th century, lemon balm has been used to heal wounds, treat venomous insect bites, reduce stress and anxiety, ease pain, and promote sleep.
Today, this member of the mint family, when combined with valerian (another calming herb), is thought to help reduce tension, lower stress levels, ease mild depression and exhaustion, lower stress-related high blood pressure, and treat mild insomnia.
Hops have been used by cultures around the world for hundreds of years to treat a wide range of illnesses and disorders. North American Indians used hops as a sedative, analgesic, and kidney and urinary aid. In India, hops are used for restlessness associated with nervous tension, headache, and indigestion. In traditional Chinese medicine, it is used to treat insomnia, restlessness, intestinal cramps, and lack of appetite.
Hops contains a naturally occurring sedative chemical known as "2-methyl-3-butene-2-ol," which makes it a good choice for treating anxiety that can lead to sleeplessness, particularly when it's combined with other herbs that contain sedating properties, such as valerian, chamomile, or passion flower -- all included in the Alteril® formulation.
Passion flower has long been used as a traditional remedy in the treatment of anxiety disorders. It is believed to work by increasing levels of a neurotransmitter called gamma amino butyric acid (GABA), which creates a relaxing effect by lowering the activity of some brain cells.
There is thought to be a synergy among passion flower, valerian, and lemon balm that makes this combination particularly useful for treating restlessness and irritability, as well as nervous insomnia, while providing mild sedation.
