Tryptophan and Depression
This amino acid is one of the more famous and the most widely studied of this group. It has been commonly used for treating depression particularly where insomnia has been a feature of this condition. Some studies have indicated that tryptophan is as effective as conventional antidepressants but this has not been confirmed.  

Tryptophan and Sleep
Tryptophan is a precursor to the manufacture of vitamin B3 and the hormones melatonin and serotonin as well as stimulating liver protein synthesis.
Serotonin is primarily responsible for the regulation of appetite and sleep. A deficiency of this neurotransmitter is associated with agression, depression and obsessive-compulsive disorders. Melatonin is the hormone that helps regulate our sleep cycles.
