Hey, we're the Selene team! Three dog parents who've all been exactly where you are right now.
We remember the moment we first noticed it...
Our dogs were slowing down.
Maybe it was the way they hesitated before jumping on the couch.
Or how they stopped pulling on the leash during walks.
Perhaps it was that blank stare when you called their name. Like they'd forgotten who you were.
For us, it was all of it.
And it broke our hearts.
No, It’s Not Just“Old Age”

Oh boy, we tried everything…
Expensive joint chews that barely made a dent
Salmon oil that made their fur shiny but didn't bring back their energy

Nothing worked.
Our dogs kept:
Sleeping through the day instead of greeting us at the door
Struggling to get up after lying down
Losing interest in their favorite toys and games
Moving stiffly, like every step hurt
Seeming confused or disoriented at night
Gaining weight no matter what we fed them
Looking at us with tired, cloudy eyes that had lost their spark
We felt helpless.
These weren't just pets. They were our family. Our kids' best friends. Our hiking buddies. Our emotional support on hard days.
And we were watching them fade away, week by week, with nothing we could do
The Real ReasonYour Best Friend Is Slowing Down
(And Why Everything You've Tried Has Failed)
Your dog isn't just "getting old." Their cells are running out of fuel.
Inside every cell in your dog's body is a molecule called NAD+ (nicotinamide adenine dinucleotide). Think of it as the spark plug that keeps everything running:
Energy production — Turns food into fuel
DNA repair — Fixes daily cellular damage
Brain function — Keeps them sharp and responsive
Joint & muscle health — Supports movement and recovery
As they get older, your dog's NAD+ levels start plummeting. By the time they're 7 years old, they already lost over 50% of the NAD+ they had as puppies.
Slow recovery → Every walk seems harder than the last
Here's the problem:

The first and only NAD+ precursor formula designed to restore cellular energy from the inside out.
After months of research, working with top veterinarians, and testing with our own senior dogs, we created something that finally addresses the root cause of aging:
A science-backed formula that restores dog's NAD+ levels naturally.

Selene NAD+ isn't just another supplement we threw together. It's been formulated with leading veterinary nutritionists and backed by decades of cellular aging research.
"NAD+ supplementation represents one of the most promising advances in canine longevity science. By addressing cellular energy at its source, we're not just extending lifespan, we're extending the quality of those years."
~Dr. Simons Bachr, DVM, Veterinary Nutritionist
Our formula is based on the same longevity science used in human NAD+ supplementation, now optimized for dogs.

When I adopted my senior rescue dog, I made a promise to give him the best years of his life, however many we had left. He came to me with a greying muzzle, tired eyes, and the kind of calmness that comes from a life that hadn’t always been easy. I started giving him Selene NAD+ because I wanted to support him not just physically, but at a cellular level. The science behind it especially the NAD+ support really stood out to me. I figured if there was a way to help slow down the aging process and keep him feeling good, it was worth trying. A few weeks in, I genuinely started to see a change. He’s brighter, more alert, and even has a bit of a playful spark again. He’s not suddenly acting like a puppy, and that’s not what I expected, but he seems more present, more energetic, and more comfortable in his body.

This has made a major difference in my 15 year old dog. She was showing signs of dog dementia and just looked so sad and lost. She would barely look at anyone in the face and her legs were super stiff especially when walking down the stairs to go outside. I noticed a difference after just 3-5 days. She has much more energy and is looking at our faces. She has a much easier time going up and down the stairs and she looks much more like her old self. It broke my heart to see her the way she was before this supplement, so I wanted to share a review in case it could help someone else who’s experiencing similar symptoms with their older dog. 🩷

I have an older dog, who, in spite of getting vitamins, joint supplements, and probiotics, is visibly slowing down. I saw this advertised and thought why not try it. I bought a jar and he's been getting it for about two weeks. I kept meaning to mention to my husband that I am giving Yeti a new Old Man supplement, and ask if he noticed any difference, but just didn't get around to it. This morning, out of the blue, he asked if I was feeding Yeti something different because he's much more active than he has been in recent times. I'd say this is the only recommendation you need. He had no idea Yeti is getting this supplement, but he sees a definite improvement, and so do I. When I take him out on walks, I have noticed that instead of plodding along at a walk, he is back to jogging (which he always did when he was younger).

This stuff is absolutely awesome. We thought our dog was on her way out. She was lethargic. She wasn't responding to commands that she always responded to. She had this lost look on her face. She didn't seem to recognize anyone. It was bad. She started to become a little more alert after just a couple days. She's starting to respond to some commands and I believe she recognizes us again. For the first time in months she actually played with me. There are very few supplements that I see a noticeable change with, but this one made a huge difference. I thank God I found something that works.

I started giving these to my senior dog hoping for even a slight energy boost, and the difference is honestly wild. He’s more playful, alert, and even gets up the stairs without as much hesitation. This thing must taste amazing because he goes nuts every time I open the jar. I love that they’re packed with ingredients I actually take myself for longevity. His coat looks shinier too, and he just seems happier overall. It’s hard to explain, but there’s a spark back in his eyes. I’m beyond impressed and sticking with this long-term.

I give the supplement to all three of my dogs, ages eight, 13, and 16, and since adding it to their routine, I have noticed that they have even more energy than usual! They all enjoy eating the powder on their meal, which I have one who is super picky, so that is huge for us! I have also noticed less itching and scratching during our buggy season here in Florida and more solid poops since adding this to their routine. I would definitely recommend this for senior pups!

After 2.5+ weeks of giving to my 13 dog, she is acting younger again and has enough pep back to jump on & play fight with our 4 year old, high-energy French Bulldog who outweighs her by 18 lbs. For some time now, she had been slowing down and even just walking past her sister when the sassy young pup would bark at her face and try to jump on her to initiate play. The older dog is finally back to going chest-to chest with the younger and they get in some good energy bursts together before my old dog is worn out or showing increased signs of aging.

The Science Behind TheirTail-Wagging Transformation
Nicotinamide Mononucleotide (NMN)
NMN supports aging dogs at the cellular level by boosting NAD+ — the molecule that fuels energy, immunity, and repair. It helps improve stamina, reduce signs of aging, and promote a healthier, longer life.
Coenzyme Q10
(CoQ10)
CoQ10 supports heart health, joint comfort, and cellular energy. It helps protect against age-related decline, supports mobility, and promotes mental sharpness so your dog stays playful and full of life.
Resveratrol
A natural antioxidant from berries and grapes that supports heart, brain, and coat health. It helps improve circulation, reduce inflammation, and protect brain cells keeping dogs active and alert.
NAD+
NAD+ supports metabolism, energy, and recovery. As dogs age, NAD+ levels drop — leading to fatigue. Supplementing it helps restore energy, support muscle repair, and promote long-term cellular vitality.

This Is For You If:
You see your dog as family and refuses to accept "they're just getting old"
You have a senior or middle-aged dog (7+ years) showing signs of decline. Less energy, stiff joints, confusion, or fading spark.
You've tried other supplements without real results, and you're ready for something that fixes the ROOT CAUSE, not just masks symptoms.
You understand real transformation takes 2-4 weeks of consistency, and you're willing to invest in quality because your dog deserves more than quick fixes.
You want 3-6 more years of adventure, tail wags, and precious moments together.
This Is NOT For You If:
You're looking for instant overnight results or a miracle cure.
You're shopping by price alone and not willing to invest in research-grade ingredients.
Your dog is young (under 5) with no signs of aging decline yet.

Over the past 3 months, demand has increased by 340% as word spreads about NAD+ for dogs.
Veterinarians are recommending it. Dog parents are sharing their transformations. And our small-batch production process means we can't scale overnight.
We manufacture in small batches to ensure quality and freshness. When we sell out, it takes 4-6 weeks to produce more.
If you're reading this, we have bottles available right now. But we can't guarantee how long that will last.
Why Wait?
Every day you wait is another day your dog's NAD+ levels continue declining. Another day of:

It's a liquid, so it's super easy! You can add it to their food or give it directly. No pills to hide or powders to mix.
Because it's liquid with nanoliposomal technology, it absorbs faster and works more efficiently than most chewables or tablets.
My dog is picky, will he eat this?
Since our NAD is in powder form, you can simply sprinkle it over the food and mix it so even picky dogs won't notice it.
How fast will I see results?
Many pet parents notice small changes within the first few weeks, like more energy or smoother movement. By the second month, most dogs show big improvements in playfulness, alertness, and coat health. By month three, many dogs act noticeably younger.
Is it safe for my dog?
Absolutely. NAD+ precursors, derived from vitamin B3, have been safely used in dogs for years and are well-recognized for their role in supporting cellular health.
In humans, NAD+ supplementation has gained widespread attention for its healthy-aging benefits, and emerging veterinary research suggests similar promise for dogs. Our formula is produced in FDA-registered facilities using only human-grade ingredients to ensure the highest quality and safety.
For more information on the science behind NAD+ in dogs, you can explore this vet-reviewed resource.
Does it work for all dog breeds?
We can never guarantee results, but an overwhelming number of pet parents swear by it. Whether your dog is just starting to slow down or already showing signs of aging, our supplement is designed to support energy, brain health, and mobility. It works at the cellular level to help dogs of all sizes and breeds feel better and stay active longer.
Can I cancel my subscription?
Absolutely! You can cancel your subscription at any time—no commitments, no hidden fees.
My dog is still young, do they need this now?
Yes! Cellular aging starts long before you see outward signs. Starting early can protect your dog's cells, boost their immune system, and help them stay healthier for years to come. Think of it as setting them up for a longer, better life.
What kind of results should I expect?
You can expect a more energetic, mentally sharp, and physically active dog. Over time, many dogs show better mobility, improved coat quality, and even a brighter personality. It's about helping your dog feel great, not just adding years, but adding good years.
