These results suggested the possibility that increased NAD + levels could provide a component in the protective mechanisms that are produced by CR. Administration of NR was shown to increase NAD + levels in brain and caused reduced production of Aβ1-42. NR was shown to promote PGC1α levels in transgenic animals.
Nicotinamide adenine dinucleotide (NAD +) is an essential and pleiotropic coenzyme involved not only in cellular energy metabolism, but also in cell signaling, epigenetic regulation, and post-translational protein modifications. Vascular disease risk factors are associated with aberrant NAD + metabolism. Conversely, the therapeutic increase of
NAD+ or NADH are two different forms of NAD. NAD+ has been used through different routes (IV, subcutaneous & oral) to elevate NAD levels and treat certain diseases and health conditions. Our clinical studies have shown that iv infusion of NAD+ does not increase NAD levels and subcutaneous injection of NAD+ only increase NAD levels modestly.

The three treatment arms were tested in the same cohort of 5 healthy adults. Oral supplementation of 500 mg nicotinamide led to a significant increase in blood NAD + after 12 h and showed a trend of increase after 48 h (P = 0.056), whereas 100 mg nicotinamide or water intake only did not change the NAD + levels in the same subjects.

In particular, an increase in cellular NAD(+) levels has beneficial effects, likely because of the activation of sirtuins. Previously, we reported that CD38 is the primary NAD(+)ase in mammals. Moreover, CD38 knockout mice have higher NAD(+) levels and are protected against obesity and metabolic syndrome.
