Vitamin B3 Study
 

While the study was for Alzheimer's, it is still important. Also, this should be kept in mind as well:
"
Nutrient deficiency of long standing may create a nutrient dependency. A nutrient dependency is an exaggerated need for the missing nutrient, a need not met by dietary intakes or even by low-dose supplementation. Robert P. Heaney, M.D., uses the term "long latency deficiency diseases" to describe illnesses that fit this description. He writes: "Inadequate intakes of many nutrients are now recognized as contributing to several of the major chronic diseases that affect the populations of the industrialized nations. Often taking many years to manifest themselves, these disease outcomes should be thought of as long-latency deficiency diseases. . . Because the intakes required to prevent many of the long-latency disorders are higher than those required to prevent the respective index diseases, recommendations based solely on preventing the index diseases are no longer biologically defensible." (8) Where pathology already exists, unusually large quantities of vitamins may be needed to repair damaged tissue. Thirty-five years ago, in another paper, Hoffer wrote: "The borderline between vitamin deficiency and vitamin-dependency conditions is merely a quantitative one when one considers prevention and cure." (9)"
