Both NAD + and NADH strongly absorb ultraviolet light because of the adenine. For example, peak absorption of NAD + is at a wavelength of 259 nanometers (nm), with an extinction coefficient of 16,900 M −1 cm −1. NADH also absorbs at higher wavelengths, with a second peak in UV absorption at 339 nm with an extinction coefficient of 6,220 M −1cm −1. [10] This difference in the ultraviolet absorption spectra between the oxidized and reduced forms of the coenzymes at higher wavelengths makes it simple to measure the conversion of one to another in enzyme assays – by measuring the amount of UV absorption at 340 nm using a spectrophotometer.

Mills KF, et al. (2016). Long-term administration of nicotinamide mononucleotide mitigates age-associated physiological decline in mice. NAD + is also consumed by different NAD+-consuming enzymes, such as CD38, CD157, PARPs and the NAD-dependent deacetylases ( sirtuins,such as Sir2. [76]). [77] These enzymes act by transferring an acetyl group from their substrate protein to the ADP-ribose moiety of NAD +; this cleaves the coenzyme and releases nicotinamide and O-acetyl-ADP-ribose. The sirtuins mainly seem to be involved in regulating transcription through deacetylating histones and altering nucleosome structure. [78] However, non-histone proteins can be deacetylated by sirtuins as well. These activities of sirtuins are particularly interesting because of their importance in the regulation of aging. [79] [80] The real breakthrough that occurred recently is our understanding of how to get NAD levels closer to those of our youth,” says Professor Andrew Salzman, MD, a Harvard Medical School alumni and a prominent drug inventor who’s leading NAD and NMN research at Wonderfeel®. a b Hwang SJ, Durnin L, Dwyer L, Rhee PL, Ward SM, Koh SD, Sanders KM, Mutafova-Yambolieva VN (2011).

PMC 3031738. PMID 20875415.Your NMN levels naturally decline over time, and, as a result, your levels of NAD decline, too. This may contribute to some of the health effects you might experience during aging. NAD+ supplementation comes in various forms – IV, injection, orally in pill or liquid form. The most popular options are NAD+ IV therapy and supplements containing NAD+ precursors. According to Angelova, “the safest way to increase NAD+ levels, as proven in clinical studies, is through intravenous (IV) administration directly with NAD+”. In a further step, some NAD + is converted into NADP + by NAD + kinase, which phosphorylates NAD +. [34] In most organisms, this enzyme uses adenosine triphosphate (ATP) as the source of the phosphate group, although several bacteria such as Mycobacterium tuberculosis and a hyperthermophilic archaeon Pyrococcus horikoshii, use inorganic polyphosphate as an alternative phosphoryl donor.

In addition, exercise – especially resistance training and HIIT – has been found to ignite the body’s NAD+ production pathway. “A recent study examined metabolites in the muscle tissue from younger and older adults, finding that adults who exercised rigorously had NAD+ levels similar to those of young adults,” says Angelova. a b c Billington RA, Bruzzone S, De Flora A, Genazzani AA, Koch-Nolte F, Ziegler M, Zocchi E (2006).
