You are indeed right.  Foods that are high in tryptophan like turkey
can be converted into melatonin by the entero- chromaffin cells of the
gastrointestinal tract.  So I would suggest trying turkey or turkey baby
food as a supplement to try to raise the melatonin level.  I do not know
if it will raise the melatonin level high enough to help prevent adrenal
gland disease but it will not hurt.  Plus it might help prevent
insulinoma too.
 
Hope that helps,
