Marz sleep spray | How to Use | Side Effects

Marz sleep spray is a natural product/medicine that is used to treat insomnia. It is probably the most popular OTC (over the counter) sleep product. It contains six natural ingredients that help you to fall asleep by reducing the time that you need to fall asleep when you turn off the lights. Marz sleep spray also improves sleep quality, which reflects quality of life. Marz sleep spray contains the following ingredients:

  • Melatonin (hormone that is released in the body during sleeping and is responsible for regulation of sleep-wake cycles). Studies have shown that this hormone improves sleep quality, sleep latency and total sleep time 1
  • 5-Hydroxytryptophan (essential amino acid that increases the serotonin concentration in the blood which lead to better sleeping). There are many products on the market that contain 5-Hydroxytryptophan but this amino acid should never be used alone, because it may cause side effects. However, if used in combination with other ingredients, it is very effective for insomnia.
  • Lemon balm leaf (a plant proved to have calming effect). This plant rarely causes side effects, but it should be avoided in children younger than 12 years, pregnant and lactating woman because of lack of data on its use and efficacy in these patients.
  • Inositol (vitamin B8). There are studies that show a beneficial effect of this so-called vitamin on sleeping.
  • GABA root or gama-aminobutyric acid is a neurotransmitter that has an inhibitory effect on the nervous system, which eases your sleep.
  • Valerian (a plant very commonly used to treat insomnia). It facilitates sleep onset, extends it and deepens it, with no side effects on the REM stage. It also acts as a psychostimulant and improves mood. In contrast to the benzodiazepines (most commonly used medicines to treat insomnia), it causes no residual drowsiness in the morning. It is contraindicated in children younger than 14 years, pregnant woman, breastfeeding mothers and patients with hepatic impairment. It may cause gastrointestinal disorders, allergies, headaches, anxiety, sleep disorders, mydriasis and cardiac rhythm disturbance. Chronic use of high doses of valerian for several years increases the possibility of occurrence of physical and psychological dependence if you suddenly discontinue its use.

As you can see, Marz sleep spray contains six natural ingredients, and all of them are proved to be effective for treating insomnia. There is no doubt that this spray will improve your sleeping and help you fall asleep. However, its positive effect on nightmares has not been shown. It cannot be used to treat other sleep disorders, just for treating insomnia.

How to use Marz sleep spray

Marz sleep spray is very easy to use. Just spray it directly into your mouth, preferably under the tongue as this way of application will speed up its absorption. After you spray under the tongue, close your mouth for 5 minutes. You can expect effects 30 minutes after spraying under the tongue. If you are not happy about spraying under the tongue, you can just spray it into 1 cup of water and drink it. However, this way of application will lead to slower absorption which means that it will work much slower than if used under the tongue. This way of application should be avoided.

You should use Marz sleep spray 30 minutes before sleeping.

How much to take

Use 3-5 sprays under the tongue half an hour before sleeping.
