Scientists have alleviated symptoms of the rare premature aging disease ataxia-telangiectasia using NAD+ supplementation in a mouse model [1]. This success deepens our understanding of the role NAD+ plays in aging. The ubiquitous facilitator The coenzyme nicotinamide adenine dinucleotide (NAD+) is one of the foundations of life as we know it, and it may have...

Nicotinamide adenine dinucleotide is essential for life The coenzyme nicotinamide adenine dinucleotide (NAD+) serves critical functions in our cells, such as electron transport, cell signaling, and DNA repair. Found in the cells of all mammals, NAD+ is essential for life and is linked closely to metabolism and aging. Accumulating evidence suggests that NAD+ systemically declines...

There has been a lot of attention given to the NAD precursors nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR), sold as dietary supplements, to restore nicotinamide adenine dinucleotide (NAD) levels. However, a new study suggests that there could be a new game in town with the arrival of reduced nicotinamide mononucleotide (NMNH). Introducing nicotinamide adenine...

What is nicotinamide adenine dinucleotide? Nicotinamide adenine dinucleotide (NAD+) is a key coenzyme found in all living cells. It is a dinucleotide, which means that it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base, and the other contains nicotinamide. NAD+ is essential for life, one of the most...

Welcome to part two of a two-part series exploring NAD+ biology; you can find part one here. There are already a myriad of excellent reviews on NAD+ biology in general [1-3], so, in this article, we will be mainly focusing on the NAD+ precursor nicotinamide mononucleotide (NMN). NMN and synthesis of NAD+ NMN can be...

This is part one of a two-part article where we take a look at NAD+ biology, its history, how it relates to the biology of aging, and the potential for therapeutic interventions via the so-called NAD+ precursors. What is NAD+? Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. It is a...
