TRYPTOPHAN is an essential amino acid (which means it can only be obtained through the diet) so that the brain secretes melatonin and serotonin, a cerebral neurotransmitter.
The concentration of serotonin in the brain is proportional to the concentration of tryptophan in the plasma. Taking tryptophan increases the amount of serotonin in the plasma, brain and levels throughout the body as a whole.
The principal functions of tryptophan are:
- It is one of the essential amino acids, and therefore necessary to enable to organism to build its own proteins.
- Neurones (nerve cells) use it to produce serotonin, a chemical messenger that amongst other functions, favours relaxation.
- In addition, for every 60mg of tryptophan, the human body produces 1mg dof Vitamin B3 (Niacin)
