Orthomolecular Psychiatry : Treatment of Schizophrenia

Copyright 1973, W.H. Freeman and Company.  ISBN 0716708981

Edited by David Hawkins and Linus Pauling

This is an old book and a technical one, but it discusses the relationship between schizophrenia and an increased need for niacin.  For those that this therapy helps, it appears to be striking.  Of course, this would make one wonder about other mind illnesses and niacin.
