Therapeutic Potential of NAD-Boosting Molecules: The In Vivo Evidence

Abstract: Nicotinamide adenine dinucleotide (NAD), the cell's hydrogen carrier for redox enzymes, is well known for its role in redox reactions. More recently, it has emerged as a signaling molecule. By modulating NAD-sensing enzymes, NAD controls hundreds of key processes from energy metabolism to cell survival, rising and falling depending on food intake, exercise, and the time of day. NAD levels steadily decline with age, resulting in altered metabolism and increased disease susceptibility. Restoration of NAD levels … Show more

“…For example, Nicotinamide adenine dinucleotide (NAD), the hydrogen carrier for redox enzymes, is known for its important roles in redox reactions. NAD + levels are closely associated with energy metabolism and disease susceptibility [36]. Increasing cellular NAD + levels by treatment of the NAD + precursor, nicotinamide riboside can protect against liver injury in a SIRT1-dependent fashion [37].…”

“…By 2050, $1 trillion will be spent yearly on those 65 years of age or older due to neurodegenerative diseases like dementia. [13] A current and rather controversial question regarding the cofactor is whether one's healthspan or lifespan depends heavily on one's NAD + levels. Since NAD + is the rate limiting cofactor of sirtuin enzymes, the decline of the cofactor with age has been linked to steady declines in sirtuin activity.…”

“…[15] The inevitable decline of NAD + is being combated through the use of oral supplements of the vitamin B 3 complex such as nicotinamide, nicotinic acid (niacin), nicotinamide mononucleo-tide (NMN), and NR, Figure 1, as well as sirtuin activating compounds like resveratrol. [11,13] NR, as well as NMN (i. e., the phosphorylated form), may be consumed daily from vegetables, fruits, and meat. [16] Niacin was generally used as an NAD + booster until severe flushing and itching caused by the supplement deterred users.…”

“…Thus, NAD is considered a nexus for metabolism and aging. Numbers of studies show that NAD levels decrease with aging in multiple organs and that declines in intracellular NAD concentrations are related to various aging‐associated phenotypes (Canto et al., 2015; Rajman, Chwalek, & Sinclair, 2018; Yoshino, Baur, & Imai, 2017). Therefore, increases in intracellular NAD levels may combat with aging‐associated diseases.…”
