Daily longevity for dogs

Dogs don't live long enough.

staye is a once-daily longevity drink built on the molecules that matter — NMN, CoQ10, astaxanthin, taurine, and live probiotics, in a bone broth base dogs actually want to drink. Clean, science-backed, nothing unnecessary. One packet, stirred into water. More mornings.

BONE BROTH · DAILY LONGEVITY
stir into water. that's it.
The ritual

A packet. A bowl. A morning.

One single-serve packet, stirred into a small bowl of water until it turns a warm gold. No pills to hide. No chews loaded with sugar. The bone broth flavor is the honest part — it's what makes a dog actually want to drink it, so the science gets where it's going.

01

Tear at the notch.

A precisely measured serving in foil-lined matte cream paper. No spoons. No mess. No guessing.

02

Stir into a small bowl of water.

About six ounces, room temperature — not the whole bowl. It dissolves clean and turns gold from the astaxanthin. The bone broth aroma does the rest.

03

Watch them drink.

That's it. Daily, before the walk. Fresh water always stays alongside it. Same hand. Same bowl. Same sun on the same floor.

The science

Eight ingredients. One reason.

Every ingredient earns its place in the packet. No filler. No theater. Each one is here because the evidence — in dogs, in companion mammals, or in mechanistic studies on aging — says it should be. And the bone broth flavor? That's the honest part: aroma is what makes a dog actually drink it.

NMN
NAD+ Precursor
Cellular energy. The headline molecule.

Nicotinamide mononucleotide is the precursor your dog's cells use to manufacture NAD+ — the coenzyme mitochondria need to make energy. NAD+ falls steadily with age. Fully water-soluble. Formulated for adult dogs only (12 months and up).

CoQ10
Mitochondria · Heart
Energy production where it matters most.

Ubiquinone shuttles electrons through the mitochondrial chain, concentrated in the heart muscle. We use a micellized, water-dispersible form so it actually absorbs from a drink — the plain oil-based version simply doesn't.

Astaxanthin
Antioxidant
The strongest antioxidant in the bowl.

A carotenoid from microalgae, in a water-dispersible beverage form that turns the drink a warm gold. Crosses the blood-brain and blood-retinal barriers and neutralizes free radicals far more efficiently than vitamin E.

Taurine
Cardiac
The amino acid a dog's heart runs on.

Taurine status is directly tied to canine heart health — low taurine is a known driver of dilated cardiomyopathy. Fully water-soluble, exceptionally safe, and one of the few claims here that's genuinely well-evidenced in dogs.

L. acidophilus
Probiotic
A founding species in the canine gut.

Live Lactobacillus acidophilus, lyophilized to stay viable in the dry packet. Foundational to gut barrier integrity and the gut-immune axis, which together account for roughly 70% of immune activity.

B. animalis
Probiotic
The partner strain. Calm guts, steadier days.

Bifidobacterium animalis is one of the most studied probiotics in companion animals. Supports stool quality, immune modulation, and the short-chain fatty acids that feed colon cells directly.

Goat Milk
Gut · Palatability
Why your dog finishes the bowl.

A measure of goat milk powder — lower in lactose than cow's milk and gentle on most adult dogs. It earns its place twice: light gut and immune support, and the creaminess that makes the drink something a dog looks forward to.

Bone Broth
The Reason They Drink It
Aroma is most of the battle.

Dogs drink with their nose first. A low-sodium bone broth flavor gives the drink the savory aroma that makes a dog want it — no salt loads, no onion, no garlic. It isn't pretending to be medicine. It's the reason the medicine gets consumed.

AND NOTHING ELSE
No xylitol. No onion. No garlic. No added salt. No sweeteners. No dyes. No filler. If a molecule isn't on this page, it isn't in the packet.

staye is formulated for adult dogs (12 months and up). NMN is not appropriate for puppies — they already make plenty of NAD+ on their own.

The fat-soluble actives use water-dispersible forms built for beverages, so they absorb from a drink rather than passing through. The probiotics are lyophilized at multi-billion CFU and guaranteed live through end-of-shelf-life.

The goat milk is low-lactose and well tolerated by most dogs; a truly dairy-sensitive dog should ease in. If your dog has a heart, kidney, or liver condition or takes daily medication, talk to your vet — or ours — before starting.

The dog who started it
The story

We built this because we weren't ready.

Nobody gets enough time with their dog. staye started as a refusal to accept that — and a decision to do something about it, every single morning.

It began with a feeling more than a formula: that the years go too fast, and that the dog asleep in the afternoon sun deserves a real shot at more of them. The pet aisle was mostly sugar, oil, and marketing. Nothing was built the way we'd build something for ourselves.

So we built it the other way around. We started from the molecules with the best evidence for healthy aging — NMN, CoQ10, astaxanthin, taurine, live probiotics — and obsessed over getting the doses and forms right for dogs, not humans. Water-soluble where it needed to be. Safe for every day. Nothing included that a healthy dog doesn't actually need.

Because the whole point is more mornings. More afternoons on the warm floor, in the patch where the sun comes in.

Duke is twelve. Three months in, my husband stopped me in the kitchen and asked what I'd changed — he was watching Duke jog up the stairs. I cried. Then I subscribed for two more.

I take NMN myself. The idea of giving my dog something formulated with the same seriousness — not a hundred-dollar bag of "premium" kibble — was the entire reason I tried staye. Six months in, it's the only product I'm sure I'll never quit.

I'm a veterinary tech. I read the panel before I ordered it. The doses are right. The forms of the ingredients are right. Nothing about this is marketing — and that, frankly, is rare in our category.

My vet asked what I was giving him because his bloodwork at fourteen looked like a much younger dog's. I forwarded her the ingredient panel. She started recommending it to her other senior patients the same week.

He won't take pills. He sniffs out chews. But staye stirred into his water, he drinks like it's a treat — I think it's the smell. Nine months in, we haven't missed a morning.

I lost my first dog to lymphoma at nine. When I got Olive, I told myself I wouldn't make the same mistakes. staye is part of how I'm trying to keep that promise. The packaging makes me feel like a serious person about it.
