Why Your Pet's Cells Need NAD+ Too

Every time your pet curls up beside you, their cells are running the same fundamental biological machinery as yours. The mitochondria powering your golden retriever's morning sprint work identically to the ones fuelling your own workout. And the molecule at the centre of it all — NAD+ — is just as critical for your pet's health as it is for yours.

If you already supplement with NMN for your own longevity, you've probably wondered: what about the four-legged family members who share your life? The answer starts with understanding a simple but powerful truth — your pet's cellular biology doesn't play by different rules.

What Is NAD+ and Why Does Every Cell Need It?

Nicotinamide adenine dinucleotide — NAD+ — is a coenzyme found in every living cell. It's not a vitamin, a mineral, or an optional extra. It's one of the most fundamental molecules in biology, and without it, life at the cellular level simply stops.

NAD+ does three critical jobs:

• Energy production — NAD+ is essential for mitochondrial function. It helps convert nutrients into ATP, the energy currency that powers every cellular process.
• DNA repair — Cells accumulate DNA damage constantly. NAD+ activates enzymes called sirtuins and PARPs that repair this damage before it becomes permanent.
• Cellular signalling — NAD+ regulates hundreds of biological processes including inflammation response, circadian rhythm, and gene expression.

This isn't unique to humans. Every mammal — dogs, cats, horses, even hamsters — relies on exactly the same NAD+-dependent pathways. The cellular machinery is conserved across millions of years of evolution.

Your Pet's NAD+ Decline Mirrors Your Own

Here's the uncomfortable reality: NAD+ levels don't stay constant. They decline significantly with age, in every mammal studied. In humans, NAD+ levels can drop by 50% between the ages of 40 and 60. In dogs, the timeline is compressed — that same decline can happen by age 7.

The visible signs of NAD+ decline in pets are ones every pet owner recognises:

• Less enthusiasm for walks and play
• Slower recovery after exercise
• Joint stiffness, especially in the morning
• More time sleeping, less time engaging
• Dull coat and slower wound healing

These aren't just inevitable consequences of ageing. They're downstream effects of cells that no longer have sufficient NAD+ to maintain energy production, repair DNA damage, and regulate inflammation. The decline is real, measurable, and — critically — addressable.

From Human Science to Pet Science

At Renue By Science, we've been at the forefront of NAD+ supplementation for humans since our founding. Over 100,000 customers trust our patented liposomal NMN technology. For years, we heard the same question from them again and again:

We understood the impulse. When you experience the benefits of supporting your own NAD+ levels, you naturally want the same for the family members who greet you at the door. But our human formulations weren't designed for pets. The liposomal NMN powder didn't dissolve well in water, tasted terrible mixed into food, and pets simply refused it.

So we went back to the lab. The goal: deliver the same bioavailable liposomal NMN in a format pets would actually eat. The result was our Pet NMN Longevity Chews — soft chews that dogs treat as treats and cats accept willingly.

Why the Delivery Method Matters

Not all NMN supplements are created equal — for humans or pets. The challenge with NMN is that it's fragile. Stomach acid and digestive enzymes can break it down before it reaches the cells that need it. This is why bioavailability — the amount that actually gets absorbed — matters enormously.

Our patented liposomal delivery technology wraps NMN molecules in a protective lipid layer. Think of it as a microscopic shield that protects the NMN through the harsh environment of digestion, delivering it intact to the cells where it's needed.

This isn't a gimmick. It's the same peer-reviewed technology that has made our human supplements industry-leading. We didn't develop a "pet-grade" version. Your pet gets the same delivery technology, the same third-party testing, and the same published certificates of analysis as our human line.
