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

A packet. A bowl. Every 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.

1

Tear at the notch.

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

2

Stir into their water bowl.

Empty one packet into your dog's normal bowl of water, about 12 to 16 ounces, and stir until it dissolves into a warm, savory broth. The bone broth aroma does the rest.

3

Make it the morning ritual.

Wake up, feed the dog, set down their water with staye stirred in, then start your day. It folds into the morning you already have, the same bowl at the same time, like your own coffee. Consistency is the whole point: the mornings you don't skip are the ones that add up.

What it supports

Five systems, one daily drink.

staye is built around the parts of a dog that age first. Here is what each serving works on, before we get into the molecules behind it.

Cellular energy

Nicotinamide riboside fuels NAD+, the coenzyme mitochondria need to turn food into energy, the engine that quietly fades with age.

Heart health

Taurine supports the aging canine heart, where low taurine is a known and preventable risk for dilated cardiomyopathy.

Gut & immunity

A live probiotic feeds the microbiome while L-glutamine fuels the cells that line the gut, two-sided support for the place most of your dog's immune system lives.

Healthy aging

Higher NAD+ supports the cellular maintenance and repair pathways that quietly slow down as a dog gets older.

Joint & mobility

Undenatured type II collagen works through oral tolerance to support joint comfort and easier movement as the years add up.

The science

Six 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.

Nicotinamide Riboside
NAD+ Precursor
Cellular energy. The molecule everyone's chasing.

NR is the precursor cells use to make NAD+, the coenzyme mitochondria need for energy, which falls steadily with age (Rajman et al., Cell Metabolism, 2018). It has a clean safety profile, and we chose it over NMN for stability in a powder format. The benefit for healthy aging is mechanistically strong but not yet a proven clinical outcome in dogs, so we won't claim one. Fully water soluble. Adult dogs only, puppies already make plenty of NAD+ on their own.

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

Taurine status is directly tied to canine heart muscle. Low taurine is a known driver of canine dilated cardiomyopathy (Backus et al., Journal of Veterinary Internal Medicine, 2003), and the 2018 FDA investigation into diet-associated DCM reinforced taurine's central role. It is the strongest canine-specific evidence on this list. Fully water soluble, exceptionally safe.

UC-II
Joint Mobility
Joint comfort through oral tolerance.

Undenatured type II collagen works through gut-associated lymphoid tissue, a small daily dose teaches the immune system to stop attacking joint cartilage, rather than trying to patch it directly. In a head-to-head trial in dogs with osteoarthritis, UC-II at 40 mg/day outperformed glucosamine and chondroitin on multiple mobility measures (Gupta et al., 2012; Deparle et al., 2005). The primary evidence is in dogs with existing joint disease; daily use as a maintenance habit in healthy dogs is a logical extrapolation, not independently proven. Supports joint mobility and comfort.

L-Glutamine
Gut Lining
Fuel for the cells of the gut wall.

Glutamine is the most abundant amino acid in the body and the primary fuel source for the cells that line the intestine (Newsholme et al., Journal of Nutrition, 2003). It pairs mechanistically with the probiotic, B. animalis feeds the microbiome and L-glutamine feeds the gut wall itself. Fully water soluble, well tolerated.

B. animalis
Probiotic
The most dog-studied probiotic there is.

Bifidobacterium animalis is the probiotic strain with the most companion-animal research behind it (Kelley et al., Veterinary Immunology and Immunopathology, 2009). Lyophilized to stay viable in the dry packet and guaranteed live through end of shelf life, it supports stool quality, immune modulation, and the short-chain fatty acids that feed colon cells directly.

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

Dogs drink with their nose first. A low-sodium bone broth 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 where it's going.

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). NR is not appropriate for puppies, they already make plenty of NAD+ on their own.

Every active is either fully water soluble or, in the probiotic's case, lyophilized at multi-billion CFU to stay viable in the dry packet and guaranteed live through end of shelf life.

UC-II is sourced from chicken cartilage, so dogs with a known chicken allergy should sit this formula out. If your dog has a medical condition or takes a daily medication, talk to your vet before starting.

Six ingredients. One daily drink. Built like the years matter.

The story

We built this because we wanted more time.

Nobody gets enough time with their dog. staye began as a refusal to accept that, a promise to Grace and Duke, kept one morning at a time.

It started with the two of them, a golden retriever and an English black lab, and the same quiet thought every owner eventually has: that the years go too fast. The pet aisle was mostly sugar, oil, and marketing. Nothing was built the way we'd build something for them.

So we built it the other way around. We started from the molecules with the best evidence for healthy aging in dogs, nicotinamide riboside for cellular energy, taurine for the heart, UC-II for joint mobility, L-glutamine and a live probiotic for the gut, and obsessed over getting the doses and forms right for dogs, not humans. Water soluble where it could be. Safe for every day. Nothing included that a healthy dog doesn't actually need.

Duke is eleven now. He takes the first batch every morning, before the walk, and he is the whole reason staye had to be built right. Because the point is more mornings. More afternoons on the warm floor, in the patch where the sun comes in, for Grace, for Duke, and for yours.

Be one of the first

We'd rather earn it than fake it.

staye is brand new. We could paper this page with five-star reviews and a big round number of "happy dogs," every supplement does. We're not going to. There's no wall of testimonials here yet, because we haven't earned one yet.

What we have instead is an honest start: a small first batch, a formula we'll defend ingredient by ingredient, and the dogs and people who believe in it early. If staye works for your dog, the best thing you can do is tell the people whose dogs you love.

Questions

The honest answers.

We won't claim it will, no one honestly can, and any dog brand promising a number of years is selling you something. Here's what's true: staye is built from the molecules with the best evidence for healthy aging in dogs: nicotinamide riboside for cellular energy, taurine for the heart, UC-II for joint mobility, L-glutamine and a live probiotic for the gut, all at doses matched to your dog. The goal is healthspan: more good days, steadier energy, a body better equipped to age well. More good mornings, honestly pursued, not years promised.

Most do, right away, the bone broth base is what makes it smell like something they want. Start with half a packet for the first few days so the flavor change is gradual, and always keep their plain water alongside it. If your dog still won't touch it, that's exactly what the money-back guarantee is for.

Yes, for healthy adult dogs. Every active sits within published canine safety ranges, taurine and the probiotic especially have wide margins. UC-II is sourced from chicken cartilage, so dogs with a known chicken allergy should sit this formula out. We deliberately left out things we couldn't justify giving a healthy dog daily, like supplemental vitamin D. If your dog has a medical condition or takes a daily medication, check with your vet before starting.

Adult dogs, twelve months and up, of any size, the dose is matched to their weight at signup. It isn't for puppies (they already make plenty of NAD+ on their own) or for pregnant or nursing dogs.

Honestly: staye is a longevity ritual, not a quick fix, and we won't promise overnight changes. The things owners tend to mention first are steadier energy, coat, and digestion over the early weeks. The real point is the slow compounding over months and years, which is exactly why it's a daily habit.

It ships monthly, quarterly, or annually, your choice, because the science only works if it happens every day. You can pause, skip, or cancel anytime from your account in a single tap, no emails, no phone calls. And if staye isn't right for your dog, the money-back guarantee has you covered.

No xylitol, onion, garlic, or grape. No added sugar, no maltodextrin filler, no dyes. If a molecule isn't on the ingredient list, it isn't in the packet.

Made in the USA in small batches at a cGMP facility, and every batch is third-party tested for purity and potency, a certificate of analysis is available on request. The probiotics carry a guaranteed live count through end of shelf life, and the formula is reviewed by a University of Pennsylvania trained veterinarian.

We currently ship within the United States only, free on every plan, sent in recyclable packaging on a cadence that matches your plan. You'll always get a heads up before a renewal ships.

One last thing

Every morning, made to count.
