Background
Nicotinamide riboside (NR) is one of the most well-studied nicotinamide adenine dinucleotide (NAD+) precursors due to its capacity to elevate NAD+ levels in the body
Mechanism of Action
Nicotinamide (NAM) is required for the synthesis of NAD+, an essential coenzyme involved in several metabolic pathways. In fact, an estimated 200 enzymes – including dehydrogenases – require NAD and NADP as coenzymes. As an electron carrier, NAD+ is necessary for oxidative reactions that occur in the cytosol and mitochondria. Due to its capacity to extract energy from substrates, NAD+ is fundamental to cellular health. NAD+ is also required for carbohydrate oxidation during adenosine triphosphate (ATP) production.
Pharmacokinetics
Absorption:
Nicotinamide is absorbed predominantly in the small intestine via facilitated diffusion. Once in the bloodstream, nicotinamide moves across cell membranes via passive diffusion.
Metabolism to NAD+:
NR acts as a precursor in producing NAD+ via two pathways:
- The NRK1/2 Pathway
NR is phosphorylated to nicotinamide mononucleotide (NMN) by the enzyme NR kinase Nrk1. The resulting MNM is then converted to NAD+ by NMN adenylyltransferase.
- The salvage pathway
NR, Nicotinic acid (NA) or NAM is converted to NMN under the influence of the enzyme nicotinamide phosphoribosyltransferase (NAMPT). NMN is then converted to NAD+ by nicotinamide mononucleotide adenylyltransferase (NMNAT aka NMN transferase).
NR has the ability to maintain intracellular levels of NAD+ in the body.4 In the first human clinical trial conducted with NR, results found that blood NAD+ levels can increase up to 2.7 fold with a single oral dose of NR.
A randomised, double-blind, placebo-controlled trial consisting of 113 people receiving NR in combination with pterostilbene (NRPT) found that the group receiving NRPT at 250mg per day had significantly increased NAD+ levels to 40% over baseline.
Elimination:
The enzyme glycohydrolase transforms NAD into adenosine diphosphate-ribose and nicotinamide. The resulting nicotinamide is then released from cells for processing by the liver. Nicotinamide undergoes methylation and oxidation in the liver – its metabolites are then excreted in the urine. Much of the free nicotinamide is reabsorbed into the body via glomerular filtrate
Figure 1: The salvage pathway
In the salvage pathway, the precursors are converted into an intermediate called nicotinamide mononucleotide (NMN) through nicotinamide phosphoribosyltransferase (NAMPT). Then NMN is converted into NAD+ via nicotinamide mononucleotide adenylyltransferase (NMNAT). NAD+ generated by this pathway is consumed by multiple enzymes including sirtuins, PARPs, and cADPR synthases.
Figure 2: The NRK1/2 Pathway.4
NRK 1/2 mediated NAD+ biosynthesis pathway. Nicotinamide riboside (NR) is metabolised by nicotinamide riboside kinase (NRK 1/2) to nicotinamide mononucleotide (NMN) and subsequently converted to NAD+ by NMN-adenylyltransferase (NMNAT) activity).
