NAD+ and aging: what is the link between the two?

No molecule is mentioned as often in the anti-aging conversation as NAD+. It is said to be the key to staying young, to more energy, to a slower biological clock. It's high time to separate the hype from the facts: what is the real link between NAD+ and aging?

In this article, we look at what aging actually is, how NAD+ relates to it via sirtuins, and what research does and does not show. No empty anti-aging promises, but an honest story. Are you curious about the basics? Then read our article on what NAD+ is and how it works.

Aging is a process, not a switch

Aging is not a switch that flips one day. It is a gradual accumulation of wear and tear at the cellular level: DNA that gets damaged, mitochondria that become less efficient, cells that enter a kind of dormant state, and low-grade inflammation that increases. Researchers summarize these processes as the hallmarks of aging.

The interesting thing is that NAD+ touches on several of these processes. Not as a miracle cure, but as a co-enzyme that simply participates in many places.

How NAD+ relates to aging

The common thread runs through sirtuins, a family of maintenance enzymes that use NAD+ as fuel. As long as there is sufficient NAD+, sirtuins can do their work around DNA maintenance, mitochondrial function, and tempering inflammation. If NAD+ decreases, the activity of these enzymes also decreases.

Because NAD+ levels decline with age, the appealing thought arises: if you reverse that trend, do you also slow down aging? That is precisely the question much longevity research revolves around, and for which there is no conclusive answer yet.

The sirtuin and resveratrol link

This is also where the name David Sinclair repeatedly comes up. He links sirtuins to substances like resveratrol, which are said to support sirtuin activity, and sees NAD+ as the fuel that keeps this entire system running. Formulas that combine NAD+ support and resveratrol are built on this idea.

A similar longevity logic, namely intervening in cellular metabolism, can be seen with ingredients like berberine; to understand how this works, read our article on the effects of berberine.

Can you reverse aging with NAD+?

Time for the honest answer, because this is where facts diverge from marketing. NAD+ and sirtuins demonstrably play a role in processes related to aging. But from that mechanism to the promise that a supplement will stop your aging or turn back your biological clock is a big leap. That leap has not been proven in humans, and "not proven" is different from "impossible": it means the evidence simply isn't there yet.

Precursors like NR measurably increase NAD+ levels, that much is certain. Whether that translates into slower aging is an open question. Anyone who promises you a proven anti-aging effect now is ahead of science. And that's precisely the kind of "anti-aging" promise that doesn't make it through our selection: at BeatsWell, we deliberately choose quality and what is supported by science with experts. And not to attach a nice marketing claim to it, by pretending that it will give you radiant skin. More about what really works and what is marketing, you can read in NAD+ supplements: what really works.

If you want to support NAD+ as part of a well-considered longevity routine, you can do so through lifestyle and through a NAD+ precursor. We select based on factors such as production, ingredients, absorbability, and independent product testing, selected according to our selection process.

NAD+ and aging: sober support

The link between NAD+ and aging is real, but more nuanced than marketing suggests. NAD+ is involved via sirtuins in processes related to aging, and levels decline with age. This makes it a logical and fascinating research topic. However, a supplement that demonstrably prevents aging does not yet exist; anyone who promises you that is far ahead of the evidence.

If you want to support your NAD+, choose an approved precursor from our NAD+ collection, and read in NR versus NMN which precursor does what.

How you are doing cellularly, you don't guess, you measure. With the right blood values, you see where you stand, and you measure those with the annual BeatsWell blood test.
