NAD+ and the Hallmarks of Aging Series – Part 6: Mitochondrial Dysfunction

Posted on by David Giacometti

Mitochondria – More than Powerplants in Cells Mitochondria are the large organelles that exist in most human cells. They are the critical organelles that generate ATP through the respiratory chain and produce the intermediate metabolites that are essential to various cellular processes.  During aging, the respiratory chain losses its efficacy and the membrane of the […]

Why Too Much NMN or NR is Bad

Posted on by David Giacometti

If not protected, NMN and NR supplements are almost entirely degraded to NAM (Nicotinamide) before reaching tissues beyond the liver. While NAM is beneficial for many health conditions, excessive NAM levels can be detrimental to your health. “high doses of NAM can cause genomic instability, reduce cellular methyl pools, and cause insulin resistance through methylated […]

Reduced Nicotinamide Mononucleotide – A Tale of Four NAD+ Precursors

Posted on by David Giacometti

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 […]

NAD+ and the Hallmarks of Aging Series – Part 5: Deregulated Nutrient Sensing

Posted on by David Giacometti

Overview Currently, available evidence strongly supports the idea that anabolic signaling (the signal that promotes growth and proliferation) accelerates aging, and decreased nutrient signaling extends longevity (Fontana et al., 2010). Further, a pharmacological manipulation that mimics a state of limited nutrient availability, such as rapamycin, can extend longevity in mice (Harrison et al., 2009). In […]

Study Shows NMN Supplementation or CD38 Inhibition Restores Cardiovascular Function in Mice

Posted on by David Giacometti

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 […]

Bacteria in Gastrointestional Tract Metabolize NMN and Impact NAD+ Metabolome

Posted on by David Giacometti

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, […]

CD73 utilization shows importance of NMN to restore NAD+

Posted on by David Giacometti

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 […]

How NAD+ Boosts ATP and What it Means for Health and Aging

Posted on by David Giacometti

Much of the attention on the benefits of restoring NAD+ levels focus on its role in activating sirtuins. However, scientific research shows that NAD supplementation has a clear beneficial effect not only on ageing itself but also on a vast range of age-related disorders through improving the levels of ATP. Declining ATP as we age […]

NAD+ is the Transport Molecule Used by the Body, Not Nicotinamide Riboside

Posted on by David Giacometti

Restoring NAD+ levels in older animals and humans is at the center of efforts to slow or even stop the effects of aging. One method being researched is providing supplements  such as Nicotinamide Riboside (NR) that the body can use to create NAD+. The chart above is from this study published in August 2019 by […]
