L-tryptophan

Description

L-tryptophan is one of 8 important irreplaceable aminoacids that has a combined action. This aminoacid is not synthesized in the body and should be received from food, biological supplements, and others. The main pharmacological functions of L-tryptophan are:

- Synthesis of protein
- Production of melatonin, serotonin, kynurenin, quinolinic acid
- Regulation of human behavior
- Improvement of psychoemotional state
- Improving the quality of sleep
- Improvement of cognitive functions
- Participation in the development of dopamine, norepinephrine, beta-endorphin
- Improvement of endocrine function
- Regulation of appetite during food disorders (bulimia, etc.)
- Reduction of cravings for alcohol and narcotic substances

In the USA, Canada and countries of the European Union, L-tryptophan is prescribed as an antidepressant and a sedative product. But unlike classical antidepressants, L-tryptophan does not have a side effect on the body and is well tolerated. This aminoacid L-tryptophan is well absorbed by the body, is quickly dissolved and goes to the blood plasma at once.

Recommendations

An influence on the production of neuroactive metabolites (serotonin, melatonin, and others) happens softer, and therefore the use of L-tryptophan is recommended as a safe alternative to synthetic sedative supplements.

When is L-tryptophan prescribed?

- Depressive conditions
- Frequent mood swings
- Seasonal functional disorders
- Anxiety and other emotional disorders
- Neuroses
- Increased irritability
- Bad sleep: insomnia, frequent night awakenings, short phase of deep sleep and as a result, chronic fatigue
- Prevention of migraine

In what dose is L-tryptophan used?

L-tryptophan should be used before meals for better uptake of the drug. Capsules/pills may be taken with water or juice. Do not take L-tryptophan with protein cocktails and milk. To increase a concentration of L-tryptophan in the tissues of the brain and increase its bioavailability, the capsules/pills of L-tryptophan should be used with carbohydrates: sugar, chocolate, bakery products, and others.

For the prophylaxis purposes, a minimal therapeutic dose of L-tryptophan is used in the dose of 1 g per day.

To treat insomnia, L-tryptophan is used in the minimal dose of 1 g before sleeping. In case of the low efficiency, a dose is increased up to 2-3 g per day. The entire daily dose should be used 30 minutes before sleeping.

To treat alcohol/narcotic addiction, it is recommended to take L-tryptophan in the dose of 1 g 3-4 times per day.

If emotional disorders, L-tryptophan is used in the dose of 1 g 2-3 times per day.

Precautions

- The use of L-tryptophan in doses more than 6 g per day is not recommended. High doses do not cause a faster therapeutic reaction but the risk of the side effects is increased
- L-tryptophan may increase a sedative action of antipsychotics, antidepressants, anxiolytics, alcohol. Therefore the dose of the sedative products should be lowered during the simultaneous use with L-tryptophan
- Do not take L-tryptophan with MAO inhibitors, tricyclic antidepressants and ISRS because they may significantly increase the level of serotonin and cause a serotonin syndrome
- The use of L-tryptophan is contraindicated during pregnancy and lactation

Possible side effects

In general, the use of L-tryptophan does not cause side effects and is well tolerated. This aminoacid is a part of our body and is required for the normal functioning. But using higher doses of L-tryptophan (more than 6 g per day) or in combination with antidepressants may cause the following side effects: drowsiness, decreased appetite, dry mouth, fatigue, and light tremor.

If you feel side effects, reduce the dose of L-tryptophan for a while.
