About Zen Sleep

Zen Sleep is a formula that has been specifically created to help individuals with sleep problems reach a relaxed state while providing the body with the required factors to produce sufficient amounts of melatonin. All that combined foster normal, healthy sleep.

How Zen Sleep Works

The core ingredient in Zen Sleep is L-theanine, followed by GABA. In fact, the product contains the same amounts of both components as the same company’s best-selling formula, Zen. Only, this time, vitamin B6, 5-HTP, and P5P have also been added to further enhance results. The new ingredients are believed to be precursors to melatonin, a hormone that helps regulate hormone levels, blood pressure, and body temperature, as well as send signals to the body that it is time to sleep, and serotonin, a sleep-regulating hormone. The combination of all these compounds helps deliver the results mentioned above.

The Wondrous L-theanine

L-theanine contributes to a number of changes that take place in the brain, which result in the facilitation of sleep and the promotion of relaxation. In detail, L-theanine:

  • Boost the levels of calming brain chemicals (i.e., GABA, serotonin, dopamine) – Neurotransmitters (these soothing brain chemicals) help regulate alertness, concentration, mood, emotions, sleep, energy, appetite, and more. Increasing their levels fosters relaxation; hence, contributes to better sleep.
  • Reduces stress-related brain chemicals – L-theanine drops the levels of chemicals that are associated with anxiety and stress, which also provides protection to brain cells against age and stress-related damage.
  • Improves alpha brain waves – Alpha waves are present when we enter REM sleep and are also linked with a state of mind where you, for instance, daydream (meaning you are not asleep but at a very relaxed mode). L-theanine appears to stimulate the release of alpha brain waves.

As a result of all these activities, L-theanine helps:

  • Improve sleep – It can help individuals with sleep issues fall asleep more easily and quickly at bedtime. It is also found that the quality of sleep is also improved, especially among children with ADHD (attention deficit hyperactivity disorder) with L-theanine as it helps lower anxiety and enables sound sleep.
  • Reduce anxiety and stress – L-theanine has anxiolytic properties, which means that it can reduce anxiety. Unlike with other compounds that also possess anxiolytic qualities, L-theanine does not have sedative effects. So, you enter a state of wonderful attentive wakefulness.
  • Positively affects stress symptoms – L-theanine contributes to the lowering of blood pressure and heart rate, which has a positive effect on the physical and mental symptoms of stress.
  • Enhance focus, learning, memory, and attention – When the body is under stress, it produces cortisol and other hormones that inhibit some brain activity, including learning and memory. L-theanine helps prevent these stress hormones from interfering with spatial learning and memory formation. Studies have also found that L-theanine can increase cognitive skills, such as attention span and the process of visual information, especially when used with caffeine.
  • Help maintain normal body weight – Getting enough sleep is key to maintaining a healthy weight. This is because when the body gets sufficient amounts of relaxation, its stress levels are usually under control, which, combined with a healthy diet, can help prevent weight gain. L-theanine’s sleep-promoting and anti-anxiety abilities play a vital role here. However, research has evidenced that L-theanine may help protect against obesity and limit fat accumulation; hence, having a more direct role in the maintenance of weight within normal levels.

Zen Sleep Ingredients

The formula contains the following compounds:

Vitamin B6 – It helps convert the amino acid tryptophan into serotonin. This, in turn, helps regulate melatonin – the sleep hormone. Also, vitamin B6 is believed to help ease irritability and anxiety in women with premenstrual syndrome, enabling them to experience calming sensations.

L-theanine – An amino acid with multiple health benefits, among which is the promotion of sound sleep.

GABA (Gamma-Aminobutyric Acid) – An amino acid produced in the brain that contributes to the reduction of neuron activity in the central nervous system and the brain, which, consequently, has a wide range of beneficial effects on the mind and body. These include a balanced mood, reduced stress, increased relaxation, pain alleviation, and a sleep boost.

L-5-Hydroxytryptophan – Its role is to create serotonin. Therefore, it is involved in the production of melatonin, which regulates the daily sleep-wake cycles and helps the body’s biological clock stay in sync.

Other ingredients: L-Leucine, microcrystalline cellulose, hydroxypropyl methylcellulose.
