Our vet-formulated NAD+ formula is supported by scientific research to increase lifespan and improve quality of life in aging dogs.

If you don't notice these benefits after starting, contact us and we'll refund your money in full.

  • More energy and playfulness
  • Excited for walks again
  • Climbs stairs and jumps on the couch easily
  • Sharper mind and focus
  • More responsive to commands and their name
  • As many owners report: “I see the spark in his eyes again.” / “He's like his old self.”

No, there are no side effects.

Our NAD+ formula is made with research-backed, human-grade ingredients in FDA-registered facilities to ensure purity and safety.

It's been safely used in dogs for years to support cellular health and overall vitality. If your dog is pregnant, nursing, or taking medication, consult your vet first.

Most pet parents start noticing subtle changes within 2–3 weeks — like brighter eyes, more alertness, or small bursts of energy.

By 4–6 weeks, improvements in mobility, mood, and overall vitality become more consistent.

After 8–12 weeks, many report steadier energy, better movement, and a happier daily routine.

Every dog is different, so results may vary depending on age, diet, and activity level.

Nicotinamide Mononucleotide (NMN): NMN helps support aging dogs by working at the cellular level. It helps boost levels of NAD+, a compound that fuels cells and naturally declines with age.

Coenzyme Q10 (CoQ10): CoQ10 is important for supporting your dog's heart health and joint comfort. It helps with cellular energy generation and may help protect the brain and body from age-related changes.

Resveratrol: This antioxidant, found in berries and grapes, helps support your dog's heart, brain, and coat health. Resveratrol supports healthy blood flow and helps protect against inflammation, which is important for addressing age-related changes.

NAD+: NAD+ is an important compound that helps support your dog's metabolism and energy levels. As dogs age, NAD+ levels naturally decline, which can lead to fatigue and slower recovery.

Give your dog the recommended daily dosage based on their weight:

  • Small dogs (< 22 lbs / 10 kg): 1/2 dropper per day
  • Medium dogs (22-55 lbs / 10-25 kg): 1 dropper per day
  • Large dogs (55-88 lbs / 25-40 kg): 1.5 droppers per day
  • Giant dogs (88+ lbs / 40+ kg): 2 droppers per day

For best results, administer the formula once daily with food to support optimal absorption.

“I've spent hundreds on joint chews, salmon oil, and multivitamins that promised to help my senior lab move easier. Nothing truly worked until we tried Selene NAD+. Within a few weeks, her stiffness eased and she started running again, like she forgot she was 11! Now I understand why it's different."

“My vet told me to look into NAD+ for aging dogs. I was skeptical at first, but after researching how it restores energy inside the cells, I decided to try Selene. Now my golden doesn't limp when getting up, and his eyes are bright again. It's like his spark came back, and even our evening walks feel like they did years ago.”

“I wasn't sure if a supplement could actually make a difference, but after a few weeks, I'm convinced. My senior lab went from sleeping most of the day to trotting around the park again. It's like his spark came back. He's more alert, playful, and even his coat looks healthier. I'm so grateful something like this exists for our dogs.”

What blew me away was how quickly I saw the difference, within two weeks my husky was zooming again. It's amazing seeing the same longevity science that helps humans finally available for dogs.”

“I came across NAD+ for senior dogs and decided to give it a try for our 8-year-old. Within just a few weeks, the change was incredible! He's more energetic, playful, and runs around the yard again. His eyes sparkle, his spirit's back, and it truly feels like we've got our joyful dog again. Thank you, Selene!”

“I read online that NAD+ is being called the fountain of youth for dogs… and honestly, I believe it. My senior pug was slowing down and showing signs of aging, but now she's full of life again. Her walks are longer, her eyes are clearer, and she's playful like she used to be. Even our vet noticed how much more alert she is, I'll never skip a scoop.”

Seeing my old dog enjoy his walks again really means a lot to me. I can't ask for miracles, but this has made his days better, and that's enough for me.

After about 6 weeks, my dog started acting more like herself again. She follows me around the house and even plays a little. I'm grateful for that.

My wife ordered this for our older beagle. I didn't expect much, but now he actually waits by the door for walks again. That hasn't happened in years.
