More years. Stronger heart.

Most options for an older dog's heart only manage the symptoms, and they're hard on the rest of the body. This works at the root, gently.

An ageing heart runs low on one thing: NAD+, the fuel inside every heart muscle cell.
Our formula uses three natural precursors to restore NAD+ levels in the heart cells, giving the heart the cellular energy it needs to keep going strong.

Is it safe for my dog?
Yes. Every ingredient is naturally occurring.
It's dairy-free, dye-free, GMO-free and allergen-free. As always, check with your vet if your dog is on prescription medication.

Ingredients
NR (Nicotinamide Riboside): converts to NAD+ quickly, giving tired heart cells an immediate energy supply.
NMN (Nicotinamide Mononucleotide): keeps NAD+ production going over time, so levels don't drop the moment a dose wears off.
Niacinamide: the foundational precursor that supports the base conversion pathway both NR and NMN depend on.
CoQ10: supports the mitochondria inside heart muscle cells that turn NAD+ into usable energy for every heartbeat.
Resveratrol: protects heart cells from oxidative stress.

Nepimi Vital NAD+ Formula
It's Not A Heart Problem.
It's NAD+ Depletion.
Every heartbeat runs on energy. And that energy comes from a 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 an older dog, NAD+ levels drop sharply. The cells are literally working on empty.
That's the coughing at night, the heavy breathing, the exhaustion after a few steps, the way they look at you with tired eyes. One cellular energy gap behind all of it.
Your vet's medication does an important job. But it was never designed to restore what the heart cells are running out of. Our formula targets that energy gap.
Restore the energy supply, and the dog you're fighting so hard to keep gets more good days.
-
Restoration
Triple-Precursor Technology rebuilds NAD+ through three pathways at once (NR, NMN, Niacinamide).
-
Delivery
Nanoliposomal liquid survives digestion and reaches the heart cells directly, unlike chews, pills and powder.
-
Protection
CoQ10 and Resveratrol guard the heart cells from oxidative stress while NAD+ does its work.
What Results Could Look Like In Less Than 3 Months

"Our 12-year-old Beagle just wasn't the same dog. He tired easily and spent most of the day resting. Since adding these drops to his routine, he's excited for walks again, follows us around the house, and greets visitors at the door like he used to."
-
"Watching an ageing dog slow down can be heartbreaking. We started using these drops as part of our girl's wellness routine, and we've been thrilled with the changes we've noticed. She's more active, more attentive, and seems to enjoy her day much more than before."
-
"After a routine vet visit, we got a reminder that our boy wasn't getting any younger. Hearing that was tough. There was a time when he barely wanted to leave his favourite spot on the sofa. Since adding these drops to his daily routine, he's been meeting us at the door again, following us from room to room, and wanting to be part of family life. Watching him become more engaged has been incredible."
What To Expect With Consistent Use of Our Science-Backed Formula
Backed by Science, Trusted by Vets
"The NAD+ research in older dogs is real, and the triple-precursor approach is what sets this apart. Medication does an important job, but the cellular energy gap is what nobody is addressing. This formula does. I recommend it to every client who isn't ready to give up on their senior dog."

How does this formula work?
NAD+ is the molecule your dog's heart cells run on. As dogs age, NAD+ levels in the heart muscle drop sharply. The heart is beating on empty.
Nepimi Vital uses Triple-Precursor Technology to raise NAD+ levels through three pathways at once, giving tired heart cells the best chance of getting the fuel they need.

Most dog parents notice the first shifts around week 2: more willingness to move and slightly easier breathing. The meaningful changes build between weeks 6 and 12. The 90-day supply is designed to take you through the full protocol.

Nepimi Vital is made with naturally occurring molecules the body already produces.
It's dairy-free, dye-free, GMO-free and allergen-free. As with any new supplement, check with your vet if your dog has a health condition or is on prescription medication.

Can my dog take it alongside their other medication?
NAD+ is a naturally occurring molecule the body already produces. It works alongside your dog's current routine by supporting what medication was never designed to touch: the energy supply inside the heart cells. As always, check with your vet before adding anything new.

My dog is already very old. Is it too late?
Earlier is better, but older dogs still respond. Restoring NAD+ to the heart cells works the same way however long the levels have been low. You may see slower progress than with a younger dog, but the protocol supports the same energy gap.

Customer Reviews
Bella is a 12 year old Cavalier and the little cough at night had me lying awake listening for it. About three weeks in I realised I hadn't heard it in days. She's back on her walks round the park and actually pulling me to the gate again. I didn't think I'd see that again.
60-Day Supply
Our Lab is 13 and spent most of the day on his bed. Two drops in his dinner every night, nothing else changed. Week 4 he started following me into the kitchen again and now he's first at the door when the lead comes out. Ordered the 3 bottles and glad I did.
90-Day Supply
Bought one bottle to try because I'm sceptical of anything like this. Our Border Terrier is 11 and had gone very flat. Two weeks in he's trotting round the garden barking at pigeons like he used to. Just ordered the 90-day supply.
30-Day Supply
Stairs had become a problem for Rosie, she'd stand at the bottom and look at me. After about a month she started going up on her own again, slowly but on her own. Easy to give too, it just goes on her food and she doesn't notice.
90-Day Supply
Our beagle is 14. Our vet said he was doing well for his age but he was so tired all the time. He's got his spark back, more interested in his food and his walks. I've recommended it to two friends at the dog park already.
60-Day Supply
I'd tried CoQ10 tablets on their own and saw nothing. This was different within a few weeks. Calmer nights, more energy in the day. Customer service were lovely when I asked about dosing for a small dog too.
90-Day Supply
Took a bit longer for us than some reviews say, nearly 4 weeks before I noticed anything. But he is definitely brighter now and sleeping better. Giving it four stars only because delivery took the full 10 days.
