1) As a rule, the more ill you are, the more niacin you can hold without flushing. In other words, if you need it, you physiologically soak up a lot of niacin. Where does it all go? Well, a good bit of it goes into making nicotinamide adenine dinucleotide, or NAD. NAD is just about the most important coenzyme in your body. It is made from niacin, as its name implies.

2) Niacin is also works in your body as an antihistamine. Many persons showing psychotic behavior suffer from cerebral allergies. They need more niacin in order to cope with eating inappropriate foods. They also need to stop eating those inappropriate foods, chief among which are the ones they may crave the most: junk food and sugar.

3) There is a chemical found in quantity in the bodies of schizophrenic persons. It is an indole called adrenochrome. Adrenochrome (which is oxidized adrenalin) has an almost LSD-like effect on the body. That might well explain their behavior. Niacin serves to reduce the body’s production of this toxic material.
