Inactive ingredients? Not here. Every part of our formula is fully intended to deliver health benefits to your pet. We avoid unnecessary additives and preservatives and we will never compromise on this standard.

How Do I Use It?

Provide one half teaspoon per 20 lbs of body weight once a day by mixing the liquid into your pet's food. New to supplements? Any changes in diet or routine can be a temporary challenge for a pet's digestive system, so we recommend starting slow to help your pet acclimate. Begin with half the recommended dosage for the first few days and slowly build up to the full dose over time.

    Exactly the kind of proactive support I wanted

    I was looking for something future focused, science informed, and gentle enough for daily use. This formula checks all of those boxes. My dog feels more resilient and consistent overall. It feels like we are doing the right thing early.

    Great support for high output dogs

    We do a lot of long walks, training, and outdoor time. Longevity One seems to help with recovery and resilience. My dog still has plenty of drive but does not seem as worn down afterward. The benefits showed up gradually but they are definitely there.

    Stress support that feels natural

    I wanted support for everyday stress without calming or sedating effects. The adaptogens in this formula help my dog stay balanced while still being herself. My cattle dog recovers better after intense days and doesn’t seem as overwhelmed.

    Proactive health without pushing too hard

    I appreciate how gentle this feels. It supports inflammation, immune balance, gut health, and antioxidants without being overwhelming. My dog handles activity better and seems more comfortable day to day. This feels sustainable long term, which is exactly what I want.
