He’s back to himself
My 9-year-old dog was slowing down a lot, but after using the NAD+ for a couple of weeks, he’s playful again. I honestly didn’t expect such a change.
Feels More Present
Bruno started showing early signs of confusion and would stare at corners or forget where his water bowl was. Since adding this to his food, he seems more aware of what’s going on around him. He makes eye contact again.
He's Back
My senior dog hasn’t done his little morning trot in over a year. Now he greets me with a tail wag and a bit more pep. Not a miracle, just a genuine improvement in his overall mood and energy.
More playful
After a few weeks with NAD+, my Bailey has way more energy. He runs around like he’s years younger, I'm so happy. She seems more like herself lately.
Helps His Focus
Rex used to wander around during simple training or completely forget what he was doing. Since giving him this daily, he pays attention longer and isn’t as spaced out. Even my vet noticed he’s acting sharper.
Back To Enjoying
My old dog just slept most of the day and didn’t show much interest in play. Now he actually joins the other dog in the yard for a bit and has more spark in his eyes. It made a difference for him.

Our New NAD+ Formula For Dogs
Your dog’s aging isn’t just “old age.” As dogs grow older, their bodies lose the ability to produce NAD+, the essential molecule that fuels every cell with energy, repair, and vitality.
Furstay & Co NAD+ replenishes this vital molecule directly, restoring the cellular power that time takes away. As NAD+ levels rise, your dog’s body begins to renew itself from within — naturally bringing back energy, comfort, and focus.
It’s like turning the lights back on inside every cell.
This isn’t another joint chew or multivitamin. It’s the only supplement that supports your dog’s health at the root cause of aging, not just the symptoms.
Real energy. Real recovery. Real results.
