Niacin Intake of a Cross-Section of the Nigerian Populace
Subscribe/Renew Journal
The nutritional essentiality of niacin has been established and available evidences show that niacin exert an important metabolic function in intermediary metabolism as a constituent of two coenzymes, NAD+ and NADP+. These coenzymes are involved in oxido-reduction reactions essential for cellular respiration and oxidative phosphorylation. Poor intake of niacin have been reported to result into the metabolic disorder called pellagra. Pellagra, which is also associated with tryptophan deficiency can manifest in psychosis with delusions and hallucinations if it is untreated. It is evident that the requirement of niacin (vitamin B3) is related, to caloric intake.
