NAD+ Precursors and Healthy Aging Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells. It is a critical coenzyme for energy metabolism and also serves as the substrate for enzymes such as the sirtuins. One of the hallmarks of aging is declining cellular NAD+ levels. Moreover, many studies carried out in different […]

CD38 Deficiency Alleviates Ang II-Induced Vascular Remodeling By Inhibiting Small Extracellular Vesicle-Mediated Vascular Smooth Muscle Cell Senescence In Mice (Lu Gan, June 2021) In this study, researchers investigated the impact of NMN supplementation and CD38 inhibition on the cardiovascular function in mice. Declining NAD+ levels are a major contributor to cardiovascular disease in mice. It […]
This recently published research by Drs. Lindsay Wu, David Sinclair and others examined the pathways that oral NMN takes to becoming NAD+ in mice. It confirmed some aspects of earlier research, and also made some surprising new findings. https://assets.researchsquare.com/files/rs-87047/v1_stamped.pdf Several experiments were completed that all measured NAD+ metabolites in the Gastrointestinal Tract (GIT) and Liver, […]
This recent study found that in endothelial cells, the extracellular conversion of NMN to NR by CD73 enzyme in the cell membrane is a key mechanism to maintain intracellular NAD+ Reversal of endothelial dysfunction by nicotinamide mononucleotide via extracellular conversion to nicotinamide riboside Like prior studies (1), they found that this transport method did not […]
The single oral administration of NMN was safe and effectively metabolized in healthy men without causing any significant deleterious effects. Thus, the oral administration of NMN was found to be feasible, implicating a potentialtherapeutic strategy to mitigate aging-related disorders in humans.
This research was published in January 2019 that found an enzyme named Slc12a8 that can transport a small quantity of Nicotinamide Mononucleotide (NMN) directly into some cells. However, this enzyme is only prevalent in the small intestine of older, sicker animals and humans. The Slc12a8 enzyme was just discovered because it plays a very minor […]
Yes, NMN can cross the cell membrane intact This research was just published that found an enzyme named Slc12a8 that can transport a small quantity of Nicotinamide Mononucleotide (NMN) directly into some cells However, this enzyme is only prevalent in the small intestine of older, sicker animals and humans. The Slc12a8 enzyme was just discovered […]
Researchers use supplementation with NMN, NR and NAD⁺ to restore levels of NAD⁺ in mice, making them look and behave like they did when young and extending their lifespan.
Although they have similar effect in some organs, there may be differences in the effect they have in other tissues throughout the body.
