Our Mission

We created the Longevity Project with a mission to give dogs better access to safe and effective support for aging and healthspan. We started as a small think tank of animal specialists and research scientists motivated by an endless frustration with pet supplement companies overpromising and under-delivering. With the right expertise and a real obsession for dogs, we knew we could develop a product that gave people better agency over the health and longevity of their pets.

What is Longevity-ONE?

Longevity-ONE is a daily foundational supplement designed to support healthy aging and whole-body function. It combines structural proteins, targeted probiotics, and bioactive plant compounds selected to reinforce the systems dogs rely on over time.

Originally developed as a liquid formula, Longevity-ONE evolved through extensive research and refinement into our cold-pressed soft chew, released in 2025. The limited-ingredient profile and low-heat process help preserve the integrity of its bioactive components for consistent daily use.

Why we stand out

While we know our product is innovative, we believe our commitment to safe sourcing and quality control is what truly separates us from the pack. Outside of keeping up with the latest research from leading institutions and veterinary journals, the most important element of our approach is our sourcing and quality assurance process.

Since we started, we've been committed to making small-batch blends that are as safe for humans as they are for pets. How can we be certain they're safe? We use human grade ingredients while avoiding additives and preservatives, and we spare no expense when it comes to testing and quality assurance. We stick to rigorous inspection standards and intensive recordskeeping while batching every formula in regulated cleanrooms. For us, testing is an extensive process that starts well before the day of manufacturing. We believe a fully auditable and transparent supply chain is critical for delivering a consistently safe and effective product.

Our pets use it too.

The input ingredients make all the difference for our pets and yours. All of our suppliers are fully vetted to make certain they share a dedication to precision and safety. Before any ingredient is used in-house, it is quarantined, sampled, and third-party tested by ISO/IEC 17025 accredited laboratories. Lastly, all materials undergo a final-pass by our own expert IQA team. Only then will those ingredients make their way into each formula.

Our approach, explained

We believe aging is not a single pathway, and support should not be either. Research increasingly shows that many age-related changes stem from shared maintenance systems. Structural proteins, immune signaling, gut integrity, mitochondrial function, and cellular repair pathways influence multiple outcomes at once. When these foundational systems are supported, resilience improves broadly rather than narrowly.

There are also shared failure points. Oxidative stress, chronic inflammatory signaling, barrier breakdown, and reduced DNA stability can influence mobility, cognition, and immune balance simultaneously. Addressing these upstream drivers is more meaningful than reacting to downstream symptoms one at a time.

Rather than chasing isolated issues, we formulate around the biological foundations that help maintain structural integrity, cellular accuracy, and adaptive balance over time.

For us, it means ingredient purity, sourcing transparency, and manufacturing standards that meet the same expectations we would have for ourselves. We avoid unnecessary fillers, artificial preservatives, and low-quality commodity inputs.

Quality is not a marketing term. It is a sourcing discipline.

Every ingredient is selected for a specific biological role and how it interacts within the broader formula. We prioritize peer-reviewed research, standardized extracts, and forms supported by canine data when available.

If it does not serve the system, it does not go in. It also must meet our rigorous standards and not land on our 'no list'.

Absolutely not. No supplement replaces the specialized care of a veterinarian. Longevity-ONE is designed as a daily foundation to complement, not substitute, professional guidance.

The strongest long-term outcomes come from proactive systems support combined with care tailored to your dog. Breed, genetics, age, environment, and diet all influence lifelong health. Supplements are one part of a broader, thoughtful approach.

If possible, find a veterinarian that will support your dog with a plan tailored just for their unique health profile.

Because most supplements are designed to address problems after they become obvious. We believe dogs deserve thoughtful support before decline begins. Longevity is not about adding years randomly. It is about supporting function over time.

That’s the mission.

We're doing something different.
