Cervalin: A complete overview

Have you heard of Cervalin ?


Since its creation, Cervalin has been the number one product at Naturiste. Many lives have been transformed by Cervalin's unique and exclusive liquid formula!


Cervalin is a great ally for people with sleep disorders such as insomnia, night wakings or inability to fall asleep. People suffering from mental disorders such as anxiety or depression, or those with attention deficit disorders, will particularly benefit from the sleep-inducing effects of Cervalin. Whether you suffer from insomnia, anxiety, depression, attention deficit, or simply sleep disorders, Cervalin will be your ally, both at bedtime and upon awakening!


Composed of L-Theanine and Melatonin, which work together to help you fall asleep faster and sleep more soundly, Cervalin is calming and relaxing. The result is a restful sleep and you will notice it as soon as you wake up. Your body and mind will be well rested and energized, and your spirit will stay sharp all day. In short, this unique combination of Melatonin and L-Theanine in liquid form produces a calming effect, relaxes the mind, and improves the quality and restorative aspect of sleep.



Ingredient Focus

Melatonin is a hormone that your body naturally produces. As a hormone, it is produced in the pineal gland of the brain. Its production actually decreases with age and is inhibited by light. Melatonin does not automatically induce sleep in people, but it does signal the body that it is time to sleep. Melatonin also contributes to better sleep by calming the body.


L-Theanine is an amino acid found in tea leaves. Identified by Japanese scientists in 1949, L-Theanine reduces psychological and physiological stress reactions. A calming effect is usually seen within 30 to 40 minutes of taking L-Theanine at a dose of 50 to 200mg. This calming effect typically lasts between 6 and 8 hours.


L-Theanine also contributes to a number of changes in the brain that promote relaxation and calm. The brain becomes more balanced due to the increase in GABA, serotonin and dopamine. These neurotransmitters work in the brain to regulate emotions, mood, concentration, alertness and sleep, as well as appetite, energy and other cognitive abilities. Increased levels of GABA, serotonin and dopamine in the body lead to reduced anxiety and increased concentration and calm. Some studies also show that L-Theanine improves attention and alertness because it reduces susceptibility to distractions.




Is sleep really a common problem?

Let's look at the statistics


It has long been assumed that one of the main functions of sleep is to repair minor daily damage and restore health and vigor. Sleep is also considered a way to manage stress.


However, sleep problems are common in the general population, with statistics showing that nearly 50% of American adults report insomnia and fatigue, and 40% of those with insomnia are also reportedly affected by a mental health disorder. For example, approximately 75% of adults with depression suffer from insomnia.


Among adults over the age of 40, 69% of men and 76% of women get up to go to the bathroom at least once a night.


In addition, as many as 70% of children with attention-deficit/hyperactivity disorder (ADHD) have mild to severe sleep problems.



When Mental Health Interferes


Many patients suffering from the majority of anxiety disorders complain about their sleep by reporting difficulties in initiating and maintaining it. This means that they have difficulty falling asleep and once asleep, they have difficulty staying asleep. Research has shown that, compared with normal subjects, patients with panic, anxiety, or depressive disorders have longer sleep latency, more wakeful times, and less efficient sleep patterns.


The links between sleep and depression are also strong. About three-quarters of depressed patients have symptoms of insomnia, and hypersomnia is present in about 40% of depressed young adults and 10% of older patients, with a preponderance in women. These symptoms cause enormous distress and have a major negative impact on quality of life.


Another interesting fact is that epidemiological studies have emphasized that insomnia in non-depressed subjects is a risk factor for the subsequent development of depression. It is therefore necessary to better manage sleep disorders in people with and without depression in order to improve the quality of life of these patients.


Good sleep is therefore essential for a better quality of life. Cervalin is a natural solution to these problems. Cervalin, with its unique formula, is specifically designed for people who experience difficulty sleeping, allowing them to fall asleep faster and sleep longer in general, resulting in a better quality of life. Thousands of our customers have reported that Cervalin has changed their lives for the better!


Cervalin is often embraced by people as soon as they try it for the first time and realize that it really works for them.



How will I feel the next morning ?


Often, ingredients such as Melatonin are effective in putting you to sleep, but when you get up in the morning, you may not be well-rested. As a result, you may feel groggy, unmotivated, tired or depressed. With Cervalin, these feelings are no longer a concern. Cervalin is not only your ally at night, but also in the morning and throughout the day. Cervalin is specially formulated to help children and adults with attention deficit disorder stay focused and alert throughout the day.


Taking Cervalin at night allows you to wake up after a good night's sleep feeling fully rested and energized. The feeling of waking up feeling great after a good night's sleep is unmatched. If you take Cervalin, you won't have to worry about crankiness, bad moods, lack of patience, and all those negative feelings that people suffer from when they are tired!


There are, of course, those who report no effect and those who say they don't notice a difference. We estimate that this happens to about 1 in 100 people. Either way, we think the comments about Cervalin speak volumes!
