Current canine nutrition standards are based on biological minimums, not performance. K9·1 closes the gap with a high-potency, fully-disclosed formula designed for daily physiological resilience.
Critical Deficiency 01
Most supplements are heat-processed, destroying the active enzymatic properties your dog needs for absorption.
Critical Deficiency 02
Generic powders are up to 60% starch and maltodextrin. K9·1 is 100% active ingredients — zero synthetic bulking agents.
Critical Deficiency 03
Oxidized bulk tubs lose efficacy within weeks. Our light-sealed daily sachets preserve nutrient density to the milligram.
Seven active complexes. One sachet. Every ingredient and dose is on the label — no proprietary blends, no rounded numbers, no marketing math.

Longevity
01 / Mobility
Bioactive collagen peptides and green-lipped mussel concentrate to maintain articular function under daily load.
02 / Digestion
Multi-strain probiotic blend (10 B CFU) with soluble prebiotic fibers to stabilize digestion and absorption.
03 / Coat
EPA + DHA marine omegas and chelated zinc for visible coat condition and barrier resilience.
04 / Immunity
Targeted antioxidants, vitamin E complex, and adaptogenic mushrooms for long-term immune resilience.
Week 1
Softer transitions between meals, more consistent stools, settled gut.
Week 3
Fur sits flatter, more reflective. Owners notice before vets do.
Week 6
Stairs, jumps, post-walk recovery — all faster. Joint stiffness fades.
Week 12
Sustained energy, immune resilience, the version of your dog you remembered.

"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."
Mira Halvorsen
Founder · K9·1 · Copenhagen
One sachet, every day. A premium aluminum tube on the counter and a calmer, more resilient dog beside you.
