What Is L-Tryptophan?


  • L-Tryptophan is one of the 9 essential Amino acids that the body cannot produce on its own and therefore must be taken from either food or dietary supplements. It is mainly present in foods such as red meat, eggs and fish.
  • L-Tryptophan has been found to be an extremely important component in processing proteins and synthesizing the neurotransmitter Serotonin (the mood neurotransmitter). In this way it works very similarly to 5HTP in which it subtly increases your serotonin levels, though not to a stage in which they can become dramatically depleted if the supplementing is ceased.
  • Deficiencies of L-Tryptophan can lead to irritability, quick temper and poor sleep. By supplementing the right amount of L-Tryptophan, improvements should be seen in aspects such as sleep, mood and focus. This is achieved through its capability of maintaining a consistent level of Serotonin through the day and its ability to aid the production of Melatonin in the night.

How Much Should I Take?
