The Mighty-K9 story

We Got Tired of Watching Good Dogs Slow Down. So We Did Something About It.

Mighty-K9 is made by a small team of dog owners in Texas, working with supplement specialists. Every dog on our team gets it every morning.

Why We Started

I'm Jeff, and this is Cooper, my 13-year-old Golden Retriever. It broke my heart when our long daily walks turned into quick, labored trips around the block because of his failing mobility.

When standard joint chews couldn't give him his playful spark back, I turned to the advanced longevity science of ESS60. It restored his vitality so profoundly that I knew I had to share this breakthrough with other senior dogs.

That is why I created our uncompromised, two-ingredient formula pure ESS60 and organic olive oil with absolutely zero fillers so your best friend can experience the exact same quality I demand for mine.

Two Ingredients That Do What Ten Others Can't

Most joint supplements try to solve the problem by adding more: more glucosamine, more chondroitin, more botanicals. More ingredients means lower amounts of each one, more fillers to hold it together, and no way to know what's actually working.

We asked a simpler question: what does an aging joint need most? Protection and lubrication. So we paired two ingredients for exactly those jobs.

ESS60: protection

A powerful antioxidant built on the carbon-60 molecule, whose discovery won the 1996 Nobel Prize in Chemistry. It helps protect joint cells from the everyday "rust" that builds up with age.

Organic olive oil: delivery

Cold-pressed extra virgin olive oil carries the ESS60 so your dog's body can use it, and supports a shiny, healthy coat. A natural bacon flavor makes it something dogs look forward to.

What's not in it:
  • Glucosamine
  • Chondroitin
  • MSM
  • Fillers
