NAD+ Intravenous Therapy: Safety and Tolerability
Multiple studies have shown that intravenous (IV) NAD+ therapy is generally safe and well-tolerated in healthy adults and elderly populations, with no major adverse effects reported during or after treatment. IV administration of NAD+ and its precursors, such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN), did not negatively impact vital signs, blood chemistry, or organ function markers, and only minor, transient infusion-related experiences were observed in some cases 1234.
NAD+ IV Therapy and Blood NAD+ Levels
IV NAD+ therapy effectively increases blood NAD+ concentrations. Studies in elderly adults and healthy volunteers have demonstrated significant rises in NAD+ levels following IV administration of NAD+, NR, or NMN. Notably, IV NR produced the most robust and rapid increase in blood NAD+ compared to IV NAD+ and oral NR, with peak levels observed within three hours post-infusion 1234.
Anti-Inflammatory and Antioxidant Effects of NAD+ IV Therapy
IV NAD+ therapy has been shown to reduce markers of oxidative stress and inflammation. In elderly subjects, repeated IV NAD+ infusions led to increased antioxidant enzyme levels (such as glutathione peroxidase-3 and paraoxonase-1) and decreased concentrations of inflammatory and oxidative stress markers, including C-reactive protein, interleukin-6, and advanced oxidative protein products . These changes suggest that NAD+ IV therapy may help counteract age-related increases in inflammation and oxidative damage 18.
Metabolic and Cardiovascular Benefits
IV administration of NMN, a precursor to NAD+, not only increased NAD+ levels but also significantly reduced blood triglyceride levels in healthy individuals, indicating potential benefits for metabolic health and the prevention of conditions like fatty liver and diabetes . In animal studies, IV NAD+ administration protected against heart damage from ischemia/reperfusion injury by reducing cell death and enhancing antioxidant capacity, suggesting possible cardiovascular benefits .
Cellular and Genetic Effects
NAD+ IV therapy has been associated with increased expression and activity of longevity-related genes, such as SIRT1 and Forkhead box O1, and reduced levels of acetylated p53, a marker linked to cellular aging. These changes may contribute to the slowing of age-related decline and improved cellular health 16.
NAD+ IV Therapy in Combination with Other Treatments
Combining IV NAD+ with umbilical cord-derived stem cells has shown promise in promoting tissue repair, reducing inflammation, and enhancing mitochondrial and metabolic function. However, more clinical studies are needed to confirm the long-term safety and efficacy of such combination therapies .
Considerations and Future Directions
While the short-term safety and potential benefits of IV NAD+ therapy are supported by current research, long-term effects and risks—such as the accumulation of toxic metabolites or the promotion of cellular senescence—require further investigation in larger and longer-term clinical trials .
Conclusion
IV NAD+ therapy is a safe and effective method for increasing blood NAD+ levels, reducing inflammation and oxidative stress, and potentially improving metabolic and cardiovascular health. It may also support healthy aging by enhancing the expression of longevity genes. However, more research is needed to fully understand its long-term benefits and risks in diverse populations 1234568.
