Autoimmune processes are involved in pancreatic beta-cell destruction in type 1 diabetes... Generation of free radicals, DNA strand breaks, activation of the enzyme poly (ADP-ribose) polymerase (PARP), and depletion of intracellular nicotinamide adenine dinucleotide (NAD) appear to be common factors in beta-cell death, whether mediated by oxygen radicals, nitric oxide, or streptozotocin.
Nicotinamide, a soluble B group vitamin which offers protection against these toxic stimuli, is at high doses a free radical scavenger, a potent inhibitor of PARP, and protects against depletion of intracellular NAD. A sound scientific rationale therefore exists for its use in human prediabetes, and promising pilot studies have been performed in ICA-positive first-degree relatives and school children.
No serious side effects have been reported from its use at the doses proposed in man or other species.
