Most organisms have several alternatives for producing the NAD+ molecule. In humans, there are three major NAD+ biosynthesis pathways: the De Novo Pathway, starting from the essential amino acid L-tryptophan; the Preiss-Handler pathway, using niacin (nicotinic acid); and the Salvage Pathway from niacinamide (nicotinamide). In this article, we’ll be covering the De Novo Pathway.
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.
The amount of time we live is called lifespan. The length of time that a person is healthy and functional—not just alive—is called healthspan. Scientific understanding in these areas is advancing rapidly. Below are 12 things the collective thinks will help on your journey to a longer healthier you.
Choosing the optimal dose for a given ingredient in our formulations is a critical and nuanced topic, so we want to share a bit about the principles that help guide our decisions at Neurohacker. Our principles derive from complexity science—the science of complex adaptive systems—and guide how we factor research and approach formulation and dosing. They take into consideration scientific evidence on the change in effect caused by differing levels of exposure (i.e., the dose-response relationship), but they do this in a way that honors complexity.
