The salvage pathway is used to produce NAD+ from nicotinamide molecules. Whether the source of the nicotinamide is vitamin B3 (as niacinamide), newer nicotinamides (e.g., nicotinamide riboside [NR], nicotinamide mononucleotide [NMN]), or molecules in food that get broken down during digestion into nicotinamide, the salvage pathway turns them into NAD+ in our tissues.
In this article we’ll be covering the “big picture” when it comes to NAD. We’ll be doing a deeper dive on specific topics we introduce in this article in subsequent articles in this series. As you go through this series of articles please keep in mind that, like other molecules in the body, NAD+ is a means to an end. We don’t care about NAD+ on its own; we care about it because of what it allows cells to do.
Selectively eliminating dysfunctional mitochondria (mitophagy) and replacing them with new mitochondria (mitochondrial biogenesis) helps us stay biologically younger. But what exactly are the functions of mitochondria and how does mitochondrial health affect aging?
Cellular senescence is one of the main contributors to the aging process and has a significant impact on healthspan. Read on to better understand the concept of cellular senescence and the evolving field of senolytics.
