What is 5-hydroxytryptophan (5-HTP)

5-hydroxytryptophan (5-HTP) is a substance that is formed in the human body from the essential amino acid tryptophan, which enters the body through food.

In the brain, 5-hydroxytryptophan, in turn, is converted to serotonin, a substance that transmits nerve impulses between brain cells.

Serotonin is also known as the "happiness hormone".

The additional intake of 5-hydroxytryptophan in the form of tablets increases the levels of serotonin in the brain and thus has a beneficial effect on conditions associated with low levels of serotonin, without causing side effects, unlike other drugs designed for these conditions.


Neolexan is intended for people suffering from conditions associated with low serotonin levels, as well as for people who follow a diet and / or give up harmful habits such as smoking, alcohol and others.

Conditions caused by low serotonin levels are:

1.1. Depression

Depression is a condition that requires specialized medical care and is different from the familiar "lack of mood" and "feeling depressed." Depression is characterized by a lack of interest in daily activities, lack of energy and ability to concentrate, feelings of helplessness, hopelessness and sadness, uselessness and inadequacy, poor sleep, decreased sexual activity, significant weight gain or loss, fatigue, headaches, etc. .

Depression is not a weakness of character and is not the fault of the patient. It can be treated. Depression is caused by a combination of factor 3 - genetic predisposition, environment and imbalance of chemicals in the brain. The most important chemical is serotonin, which is greatly reduced in depression.

1.2. Insomnia

After a good night's sleep, one feels fresh and rested. This does not always depend on the duration of sleep, but on its quality. Sleep problems also have different origins, but are ultimately due again to a disturbed balance of chemicals in the brain. The main substance on which the onset and duration of sleep depends is melatonin, but the levels of melatonin in the brain and the sensitivity of brain structures to melatonin are determined by serotonin levels.

Serotonin plays a key role in the quality of sleep. With high levels of serotonin, the phases of deep sleep are prolonged, thanks to which the brain recovers and a person feels fresh and rested, at the expense of the less important preparatory phases of sleep. While preparations containing melatonin have a certain effect in older patients with low melatonin levels, in younger people insomnia and poor sleep are affected to a much greater extent than serotonin and 5-hydroxytryptophan levels, respectively.

1.3. Anxiety and worry

Anxiety and anxiety states are also due to low levels of serotonin, so by increasing its levels, these conditions improve significantly, until their complete disappearance.

1.4. Migraine and headache

Chronic headaches and especially migraines are thought to be the result of low levels of serotonin, most likely due to its increased breakdown in the brain.

Intake of 5-hydroxytryptophan increases the production of serotonin by the body and thus reduces the sensitivity to pain. 5-hydroxytryptophan reduces the number, severity and intensity of chronic headache and migraine attacks by more than 70%.

1.5. Obesity

During diets, the levels of tryptophan in the blood and serotonin in the brain drop significantly. These low levels of serotonin in obese patients cause a strong desire to consume carbohydrates, especially sweet and subsequent overeating.

Intake of 5-hydroxytryptophan during and after a diet increases serotonin levels, which leads to earlier satiety, easier adherence to the diet, lack of overeating and weight loss.

1.6. Fibromyalgia

Fibromyalgia is a chronic condition characterized by fatigue, pain in muscles, joints and tendons, multiple points of hypersensitivity in the body, most often accompanied by low levels of serotonin.

The use of 5-hydroxytryptophan improves and helps to control the symptoms of fibromyalgia in the absence of side effects.

1.7. Bad habits

When giving up harmful habits such as excessive alcohol consumption, smoking and others, maintaining adequate serotonin levels by taking 5-hydroxytryptophan helps to more easily tolerate and comply with the restrictions and performance of daily activities in the absence of the harmful habit.

Side Effects:

At the beginning of the intake, some patients may experience mild nausea, which is transient and is best prevented by starting with low doses of neolexan, which are gradually increased as needed.

Who should not take NEOLEXAN

Pregnant women and children up to 12 years of age


The starting dose of neolexan is usually 1 tablet 3 times a day.

Usually the effect of the drug does not occur immediately, so the dose adjustment should be undertaken in case of insufficient effect after two weeks. Then the dose can be increased up to 3 times a day for 2 tablets.

In case of insomnia, it is recommended to take 1 to 6 tablets once 30-45 minutes before bedtime. As some patients may experience mild nausea when taking neolexan for the first time, it is recommended to start with 1 tablet at bedtime and increase the dose gradually as needed.

If neolexan is taken during a diet to lose weight, it is recommended to take 1 tablet 20 minutes before meals.

Do not stop taking the medicine after you feel better without consulting your doctor.

Prolonged use of neolexan does not lead to addiction and dependence.
