Spend enough time around functional medicine clinics, longevity conferences, or even high-performance athlete circles, and you’ll notice something interesting: the same three letters keep coming up.
NAD.
Not in a flashy, trend-of-the-month kind of way. More like a quiet, recurring theme, the sort that makes people lean forward and say, “Wait… explain that again.”
That growing curiosity was at the center of a recent episode of “A Healthy Point of View” podcast, where Sam Tejada, CEO and Founder of Liquivida®, sat down with Eric Huynh, Chief Revenue Officer at Wells Pharmacy Network.
What made the conversation interesting wasn’t that they treated NAD like a miracle solution. In fact, they did the opposite. They talked about it the way scientists and clinicians tend to, as something fundamental, almost unglamorous, but deeply important.
Because that’s exactly what it is.
Why Everyone Is Talking About NR Instead of NAD | Eric Huynh | Ep. 122
The Part of Your Biology You Never Think About
Most people don’t wake up worrying about cellular metabolism. We think about energy in much simpler terms, such as how tired we feel, whether we slept well, and how long it takes to recover after a stressful week.
But underneath all of that is a much quieter story unfolding inside our cells.
NAD plays a role in nearly every process that keeps those cells functioning: turning nutrients into usable energy, repairing daily wear and tear, and helping the body adapt to stress.
And here’s the part that caught many listeners off guard: NAD levels don’t stay stable forever.
They decline. Slowly. Gradually. Often, without anyone realizing it until the effects start showing up as what we casually call “just getting older.”
Why Addiction Clinics Were Among the First to Pay Attention
One of the more unexpected turns in the conversation was how NAD entered mainstream clinical use in the first place.
It wasn’t through anti-aging medicine. It was an addiction treatment.
That might seem like an odd starting point, but Eric explained it in very practical terms. Substance dependency not only affects behavior, but it also disrupts the brain’s chemistry at a physical level. Neurotransmitters get depleted. Signaling pathways struggle to rebalance.
In that context, NAD therapy began gaining attention because it appeared to support neurological repair.
Patients undergoing NAD protocols often reported that withdrawal felt less overwhelming, not magically easy, but more manageable. The fog lifted faster. Mood swings softened. Recovery felt more physiologically supported, not just psychologically guided.
For many clinicians, that was the moment NAD shifted from “interesting molecule” to “serious therapeutic tool.”
The Longevity Conversation Came Later
Once researchers started connecting the dots, NAD naturally found its way into longevity science.
Not because it promises immortality (it doesn’t), but because it sits at a crossroads of processes linked to aging: energy production, cellular repair, and inflammation regulation.
Think of it less like a shield against aging and more like maintenance for the systems that keep the body resilient.
When NAD levels drop, those systems don’t stop working. They just become less efficient. And over time, that reduced efficiency starts to show up in subtle but meaningful ways.
That’s why many experts now frame NAD support not as “anti-aging,” but as something closer to preserving function.
From IV Clinics to Everyday Wellness
For a while, NAD therapy was mostly associated with specialized clinics, long infusion sessions, tightly monitored protocols, and patients dealing with specific health challenges.
But the conversation has broadened.
The development of NAD precursors, like nicotinamide riboside, opened the door for a more accessible approach. Instead of delivering NAD directly, these compounds help the body produce its own supply.
It’s a quieter, slower process. Less dramatic. But in many ways, it reflects the direction wellness is moving, toward supporting the body’s internal systems rather than trying to override them.
What This Really Says About the Future of Health
By the end of the discussion, it became clear that NAD itself was only part of the story.
The bigger theme was a shift in perspective.
For decades, healthcare has largely revolved around treating problems after they appear. But conversations like this one point toward something different, a growing focus on resilience, maintenance, and cellular stability long before symptoms arise.
NAD happens to sit right in the middle of that shift because it touches something so fundamental: energy.
Not the kind measured in steps or calories, but the deeper biological capacity that allows the body to repair, adapt, and keep functioning over time.
And perhaps that’s why the conversation around NAD keeps resurfacing.
Not because it’s trendy. Because it forces us to rethink where health actually begins.
