Veterinarian Reviewed Formula

KYN1 combines ingredients such as NMN, omega-3, CoQ10 and antioxidants selected for their established or emerging research around cellular health, energy metabolism and healthy ageing support.

Our formula has been independently reviewed by veterinarians and designed as a daily wellness chew to support long-term vitality alongside good nutrition, movement and regular veterinary care.

Why NMN? NMN is a precursor to NAD+, a molecule involved in cellular energy and healthy ageing pathways. Research in dogs is still emerging, but NMN is one of the most closely watched ingredients in modern longevity science.

For more good years together.

Daily support for the walks, play and quiet moments that make life with a dog so special.

Why it matters

More good years together.

Ageing does not happen overnight. It shows up gradually in the everyday things: slower walks, less energy, stiffness after rest, or fewer playful moments. KYN1 is designed to support healthy ageing before those changes become obvious.

  • Supports everyday vitality, movement and long-term wellbeing.
  • Designed for proactive daily care as dogs move through adulthood and senior years.
  • Made for the owners who see their dog as family, not just a pet.

Quick questions

Before you start.

A few simple answers to help customers understand how KYN1 fits into their dog’s routine.

What age dog is KYN1 for?

KYN1 is designed for adult and ageing dogs where owners want to support long-term vitality, movement and healthy ageing. If your dog is very young, pregnant, nursing, or has a medical condition, speak with your vet first.

How do I give it to my dog?

Give the suggested number of soft chews once daily. It can be given with or without food, depending on what works best for your dog’s routine.

How long before I notice a difference?

KYN1 is designed for daily nutritional support rather than an instant effect. Many owners think in terms of consistent use over weeks and months as part of a long-term wellbeing routine.

Can I use it with other supplements or medication?

If your dog is on medication, has a diagnosed health condition, or is already taking other supplements, check with your veterinarian before adding anything new.
