In recent years, a three-letter molecule has taken center stage in the world of longevity, biohacking, and cellular health: NAD+.
If you’ve heard about NAD+ supplements, energy metabolism, or anti-aging breakthroughs, you’re not alone. But what exactly is NAD+, and why is it suddenly everywhere?
In this article, we’ll break down what NAD+ is, why it’s essential, what happens to it as we age, and what you can do to restore your levels — naturally.

What is NAD+?
NAD+ stands for Nicotinamide Adenine Dinucleotide. It’s a coenzyme found in every single cell in your body and is involved in hundreds of metabolic processes. Most importantly, NAD+ plays a central role in:
- Cellular energy production (via mitochondria)
- DNA repair
- Gene expression
- Regulation of circadian rhythm
- Activation of sirtuins (longevity-related proteins)
Think of NAD+ as cellular currency: the more you have, the better your cells perform.
Why Does NAD+ Matter?
Healthy NAD+ levels are directly linked to energy, metabolism, and resilience against cellular stress. But here’s the problem: your NAD+ levels decline significantly with age.
Research shows that NAD+ can drop by more than 50% between age 30 and 60. This decline is associated with:
- Fatigue and brain fog
- Slower metabolism
- Reduced exercise performance
- Higher inflammation
- Accelerated aging
As your NAD+ supply dries up, so does your body’s ability to repair itself efficiently.
What Causes NAD+ Decline?
Several factors contribute to the age-related decline in NAD+:
- Aging itself – natural NAD+ synthesis slows down
- Overexpression of CD38 – an enzyme that breaks down NAD+
- Oxidative stress and inflammation
- Lifestyle habits – poor diet, alcohol, lack of sleep, and chronic stress
Together, these factors create a gap between what your cells need and what they actually get.
Can You Increase NAD+ Naturally?
Yes — and that’s why the science behind NAD+ boosters is so exciting.
There are three primary strategies:
- Take NAD+ precursors – These are compounds that your body can convert into NAD+. The most researched and effective precursors are Nicotinamide Riboside (NR) and NMN.
- Inhibit NAD+ breakdown – Natural compounds like Apigenin block CD38, an enzyme that depletes NAD+.
- Improve mitochondrial health – Compounds like CoQ10, Urolithin A, and Resveratrol support NAD+ function by improving energy output and reducing cellular stress.
What Are NAD+ Precursors?
Your body doesn’t absorb NAD+ very well when taken directly, but it can absorb molecules that turn into NAD+.
One of the most researched is Nicotinamide Riboside (NR), a form of vitamin B3 that has been shown in human studies to:
- Increase NAD+ levels within hours
- Support brain and heart health
- Boost mitochondrial function
- Improve age-related metabolic markers
That’s why NR has become the preferred supplement for people looking to restore youthful NAD+ levels.
Should You Consider an NAD+ Supplement?
If you’re over 30, experiencing low energy, poor sleep, or just looking to stay ahead of the aging curve, NAD+ supplementation could be one of the smartest decisions you make for your long-term health.
And if you’re already into healthy aging, cellular repair, or biohacking — NAD+ is a cornerstone of the conversation.
