Basic information

L-tryptophan occurs naturally in foods, but only in smaller amounts than most other amino acids. However, it performs many important functions in the human body and its metabolism. The mood-lifting effects of L-tryptophan are particularly worth noting. This stems from the conversion of the amino acid into the neurotransmitter serotonin. As a precursor for serotonin, L-tryptophan contributes significantly to the balancing of our state of mind and has particularly positive effects on our sense of wellbeing.

Function:

L-tryptophan decreases appetite and reduces anxiety

 

A further important function of L-tryptophan is supporting the synthesis of niacin (vitamin B3) through its role as a provitamin. As niacin undertakes important tasks in the carbohydrate, protein and fat metabolisms and thus ensures an energy supply for the body, L-tryptophan is also of great importance for this process. Furthermore, vitamin B3 is necessary for the synthesis of some neurotransmitters and messengers, enabling the transmission of stimuli in the brain. As a component of many different proteins, L-tryptophan is also indirectly involved in many enzymatic reactions, enabling the building of different tissues through the so-called "structural proteins".

 

L-tryptophan encourages a healthy sleep pattern

 

New findings have proven that L-tryptophan can also help with a good night’s sleep; it keeps the level of serotonin fairly constant during the day, allowing enough melatonin to be produced from this serotonin during the night. This hormone significantly influences our sleep cycle and is necessary for restful sleep. Low concentrations of L-tryptophan can therefore cause problems falling asleep and even insomnia, and can considerably worsen our general state of health.

 

The Medical Uses of L-tryptophan

 

As L-tryptophan has lots of positive effects on the human body, it can be used to combat certain medical conditions and contribute to recovery. Several studies have already been carried out in order to confirm these assumptions, and have convincingly proven the effectiveness of essentialamino acids.
