Transmitting signals across the different regions of the brain is done through chemical messages called neurotransmitters, the most important being serotonin.

5-HTP (5-Hydroxytryptophan) is a metabolite of the amino acid Tryptophan and is a direct precursor of the neurotransmitter serotonin, also called the “essence of happiness.”

5-HTP is also a precursor of the melatonin hormone that regulates the wake-sleep cycle. The level of serotonin has a direct influence on the state of mind and for a restful sleep. When serotonin levels are reduced due to various causes such as daily stress, a sedentary lifestyle, inadequate nutrition as well as other aspects typical of today’s everyday life, the behavioral changes listed below appear.

5-HTP supplementation reduces the effects of low levels of serotonin in the brain. In fact, 5-HTP is converted to serotonin, but without the unwanted side effects of synthetic drugs such as Prozac. In fact, 5-HTP is a natural, clinically tested alternative to this very fashionable medicine.

Symptoms of a serotonin deficiency may be one or more of the following:

  • depression, insomnia;
  • anxiety, obsessive behavior;
  • migraines, persistent hunger;
  • aggressiveness, unsociability.

In several recent clinical trials, 5-HTP has been shown to be equal or even superior to synthetic drugs used to treat nervous depression. A study in Norway has shown 5-HTP has to significantly improve sleep. Two studies in Spain and Italy have shown that 5-HTP is effective against migraines on depressive background.
