In a new study by Brown University School of Medicine, it was shown that oral nicotinamide (NAM) supplementation decreased the incidence of keratinocyte carcinoma (KC) in high-risk skin cancer patients. NAM is converted to NAD+ in the body and it is NAD+ that is believed to be responsible for for the decrease in Keratinocyte carcinoma […]

This study was just published that documented changes in plasma and urine levels of NAD+ and its metabolites during and after 750 mg NAD+ intravenous (IV) infusion. A Pilot Study Investigating Changes in the Human Plasma and Urine NAD+ Metabolome During a 6 Hour Intravenous Infusion of NAD+ Surprisingly, no change in plasma (NAD+) or […]
Intercellular communication: communication between cells All species of animals, including the human being, are multicellular organisms (an organism that consists of more than one cell). In order to work collectively and maintain the homeostasis across multiple tissues, our cells have developed multiple different ways to receive, process, and transmit information between each other, including endocrine, […]
Two recent studies have found that inhibition of CD38 (with 78c or PCC1) increase NAD+ levels and result in significant increases in lifespan and healthspan in mice.
CD38 Increases as We Age and Drives Down NAD+ Levels CD38 is an enzyme that responds to inflammation, and consumes NAD+. Researchers have long known that CD38 levels increase, and that NAD+ decreases as we age. A 2016 study found that the increased levels of CD38 are a primary driver of decreasing levels of NAD+ […]
(Pencina et al., 2022 | The Journals of Gerontology) NMN doses of 1,000 mg taken once daily doubles NAD+ levels (middle graph). When taken twice daily, NMN triples NAD+ levels (right graph). Dr. David Sinclair is a co-founder of Metrobiotech, whose NMN product MIB-626 was used in this research published Feb 19 2022. MIB-626, an […]
There has been little, if any, head to head research published comparing Nicotinamide Mononucleotide (NMN) and Nicotinamide Riboside (NR). However, Dr. Sinclair recently said he takes NMN instead of NR based on research he did that found NR did not work at all, while NMN increased the endurance in older mice such that they were […]
Stem cells – the source of tissue homeostasis In human tissue, there are various highly differentiated cells specialized to perform distinct functions. For example, there are red blood cells for oxygen delivery, muscle cells for movement, neural cells for signal transduction, etc. These cells are vital for life but they are also prone to various […]
TMG – the Insurance Policy Against Loss of Methyl Groups TMG is one of the most important ways to restore methyl groups because as the name implies, it has three methyl groups to donate. “The reason I take glycine, specifically trimethylglycine is to counter what I think may be going on with an NAD+ booster”… […]
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 […]
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 […]
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 […]
