“NAD+ turnover is substantially increased with upregulation of genes involved in both NAD+ biosynthesis and degradation, supporting the rationale for NAD+ augmentation to attenuate disease severity.”

This research reviews the current evidence on NMN metabolism and compares the effects of different administration routes.
“Because of the high interindividual variability of the NADΔ after NMN supplementation, monitoring NAD concentration can provide valuable insights for tailoring personalized dosage regimens and optimizing NMN utilization.”
“These results indicate that NMN intake could increase blood NAD + levels, maintain walking speed, and improve sleep quality in older adults.”
A new study found injection of NAD+ using a novel liposome-like nano-particle carrier reduced overgrowth of smooth muscle cells and improved blood vessel healing in rats with narrowed arteries.
"Liposome-based NR loading is an effective strategy for improving the pharmacokinetics and bioavailability of NR, especially to the brain."
While all three precursors – Niacin, NR, and NMN – elevate NAD+ levels, their journeys within the body are distinct. Understanding these individual pathways is crucial, as they may have significant effects on outcomes beyond just the NAD+ level itself.
"Compared to traditional routes, the nasal administration of drugs can direct the rapid CNS absorption to brain tissues, thereby circumventing the hepatic first-pass metabolism and gastric degradation and allowing fast onset of pharmacological action."
“This study, involving rat and beagle MI-induced HF models, indicated that NAD+ significantly improves myocardial hypertrophy and cardiac function, inhibits myocardial fibrosis, and reduces the myocardial infarction rate.”
A recent literature review explored the impact of extracellular NAD+ on the inflammatory response.
“NMN had the highest concentrations in breast milk among the NAD-related substances. We demonstrated, for the first time, a positive relationship between NMN concentrations in breast milk and the neurodevelopmental outcome of a child.”
This study evaluated the effects of NAD+ injections in patients with heart failure.
