If you've spent any time in wellness circles over the past couple of years, you've almost certainly come across NAD+. It's been credited with everything from slowing ageing to reversing fatigue to "repairing cells at a molecular level" — language that sounds impressive, but raises an obvious question: how much of it is actually backed by solid evidence, and how much is just well-marketed hope?
Here's a more grounded look at what NAD+ is, what the science currently supports, and why that distinction matters more than most wellness marketing lets on.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every single cell in your body. Its main job is helping convert the food you eat into usable cellular energy — a process your body relies on constantly, whether you're aware of it or not. NAD+ levels are known to decline naturally as we age, which is part of why researchers — and subsequently, the wellness industry — became so interested in it in the first place. If declining NAD+ is linked to ageing, the logic goes, perhaps topping it back up could help.
It's a reasonable hypothesis. The question is how far the evidence has actually gone to confirm it.
This is the part that tends to get glossed over in most wellness content:
None of this means NAD+ is a dud, or that people shouldn't be interested in it. It means the honest answer, right now, is "promising but not yet conclusively proven in humans" — not the more dramatic claims that tend to circulate online.
There's a meaningful difference between "early research suggests a possible benefit" and "clinically proven to reverse ageing," even though wellness marketing often uses them almost interchangeably. The first is an honest, fair summary of where the science stands. The second borders on misleading — and in a space where people are making real decisions about their health and spending real money, that distinction isn't just academic.
A provider who's upfront about what current evidence does and doesn't support is generally a better sign than one leaning entirely on dramatic before-and-after testimonials or vague "cellular repair" language.
Origin of Wellness, a nurse-led IV therapy clinic based in South Perth, Australia, is a useful example of this evidence-informed approach in practice. Rather than presenting NAD+ as a guaranteed anti-ageing solution, their process involves an actual conversation about what's known, what's still being researched, and whether NAD+ is a reasonable fit for that individual client's goals and health profile — before any treatment decision is made.
It's a small shift in framing, but it's the difference between a sales pitch and an informed choice. You can read more about how they approach NAD+ specifically at origin of wellness.
The Bottom Line
NAD+ is a genuinely interesting area of ongoing research, and it's entirely reasonable to be curious about it. But if a provider — anywhere, not just in wellness clinics — is telling you it's a proven anti-ageing miracle, that's a bigger red flag than the needle itself. The better question to ask isn't "does this work," but "what does the evidence currently say, and are you being straight with me about it?"
That's a question worth asking before trying NAD+, or honestly, before trying most things in the wellness world right now.
