L-Tryptophan
An essential amino acid and precursor to serotonin (neurotransmitter), melatonin (hormone) and niacin (vitamin). High protein foods such as poultry (especially turkey), soy, eggs and fish are good sources of tryptophan. Tryptophan supplements are used to promote relaxation and sleep, although this has yet to be validated by the appropriate clinical studies.
