Built like
a wellness company.
For dogs.
K9·1 was founded on a quiet observation: the people designing the most thoughtful nutrition for themselves had nothing equivalent for the dog asleep at their feet.
We build K9·1 the way the best human wellness brands build their formulas — with named actives, full dose disclosure, third-party testing, and a daily ritual that respects how real households work.
No paw prints. No marketing math. Just a clinical-grade daily protocol designed to give your dog the best years possible.
"I built K9·1 because I was embarrassed. I tracked my own micronutrients to the milligram — and fed my dog a bag of marketing.
She deserved the same standard. Your dog does too."

The vets who
formulated it.
Every K9·1 protocol is signed off by a veterinary nutrition advisory board with combined 40+ years in canine clinical care, sports medicine, and longevity research.
"K9·1 is the first consumer protocol I've seen disclose clinical doses across mobility, gut, and immunity in a single sachet. It's what I'd formulate myself."
Dr. Elise Marchand, DVM
Veterinary Nutrition · Advisory Board
"I prescribe K9·1 to the working and sport dogs in my practice. The recovery markers and joint resilience over 12 weeks are unambiguous."
Dr. James Okafor, DVM, MSc
