This Isn't A Heart Problem. It's NAD+ Depletion.
Every single heartbeat runs on energy. And that energy comes from one molecule called NAD+: the fuel for cellular energy and repair inside every heart muscle cell.
The heart has the highest energy demand of any organ in the body. And in a dog with congestive heart failure, NAD+ levels are critically low: the cells are literally beating on empty.
That's the coughing, the labored breathing, the exhaustion after just a few steps, the way they look up at you with tired eyes. One cellular crisis behind every symptom.
Vetmedin and Lasix are remarkable medications. They control the fluid. They support the mechanical function. But they were never designed to replace what the heart cells are running out of. Our formula targets that cellular crisis directly.
Restore the energy supply, and the dog you're fighting so hard for gets more good days.
What Results Can Look Like In Under 3 Months


What To Expect With Daily Use of Our
Science-Backed Formula
The exhaustion after small movements starts to ease. They're more willing to get up. Breathing feels slightly less labored. They start having more alert moments during the day.

They're moving around the house more. Less coughing at night. Eating with more appetite. The dog that was slipping away starts showing you the one you know.
This is where dog parents say "I got more time than the vet gave us." Not cured. Not a miracle. But present, comfortable, and still themselves, and that's everything.


Backed by Science, Trusted by Vets
"The cardiac NAD+ research in dogs is real, and the triple-precursor approach is what sets this formula apart. The meds manage the mechanical failure, but the cellular energy crisis is what nobody else is addressing. This formula does. I recommend it to every client who isn't ready to give up on a dog with heart disease."

Your Money Back
We're confident in this formula because we've seen what it does: Dogs with CHF breathing easier at night, moving around the house with more energy, greeting their owners at the door.
If your dog isn't showing more energy, isn't more comfortable, isn't having more good days than bad within 90 days, you get a full refund. One email. No bottles to send back. No explanation needed.

NAD+ is the molecule your dog's heart cells run on. As dogs age, and especially as heart disease progresses, NAD+ levels in the cardiac muscle become critically depleted. The heart is beating on empty.
PetCare NAD+ Vet-Longevity uses Triple Precursor Technology to raise NAD+ levels through three pathways at the same time, giving depleted cardiac cells the best chance of getting the fuel they need to keep going.
Most dog parents notice the first shifts around week 2: typically more willingness to move and slightly less labored breathing. The meaningful changes develop between weeks 6 and 12. The 90-day supply is designed to take you through the complete protocol.
PetCare NAD+ Vet-Longevity is formulated with naturally occurring molecules the body already produces.
It is dairy-free, dye-free, GMO-free, and allergen-free. As with any new supplement, we recommend checking with your vet if your dog has a pre-existing condition or takes prescription medication.
NAD+ is a naturally occurring molecule the body already makes. It works alongside your dog's current protocol: not by interacting with the medications directly, but by addressing what those medications were never designed to touch: the cellular energy crisis inside the heart muscle. As always, check with your vet before adding anything new to your dog's regimen.
Earlier intervention works best, but later-stage dogs still respond. The mechanism, restoring NAD+ to cardiac cells, works regardless of how long the depletion has been going on. You may see slower progress than an early-stage dog, but the protocol addresses the same cellular crisis at the root of the decline.
NR (Nicotinamide Riboside): converts to NAD+ quickly, giving depleted cardiac cells an immediate energy boost.
NMN (Nicotinamide Mononucleotide): sustains NAD+ production over time so levels don't crash the moment the supplement wears off.
Niacinamide: the foundational precursor that supports the base conversion pathway both NR and NMN rely on.
CoQ10: supports the mitochondria inside cardiac muscle cells that turn NAD+ into the energy needed for every single heartbeat.
Resveratrol: protects heart cells from the oxidative damage that accelerates during NAD+ depletion and heart disease progression.
