KineticFlex Ultra
The Next Evolution of Canine Mobility Support
Our most advanced mobility formula yet, combining premium joint support ingredients with Advanced Bioactive Collagen Peptides selected because of the science behind them, not because they look good on a label.
Science First. Dogs First. Always.
Why KineticFlex Ultra?
Healthy movement depends on far more than joints alone.
Every step your dog takes relies on healthy cartilage, synovial fluid, ligaments, tendons and bone working together as one highly specialised system.
That's why KineticFlex Ultra isn't formulated around trends or ingredients that simply look impressive on a label.
We don't formulate for labels.
We formulate for biology.
Every ingredient within KineticFlex Ultra has been selected because it supports a different aspect of healthy movementāfrom cartilage and connective tissues to joint lubrication and overall mobility.
Because when science moves forward, we believe our formulations should too.
Advanced Bioactive Collagen Peptides
Not all collagen is created equal.
Traditional collagen primarily provides the building blocks used throughout connective tissues.
The advanced bioactive collagen peptides used in KineticFlex Ultra were selected because of the growing body of research investigating their interaction with chondrocytesāthe specialised cells responsible for maintaining healthy cartilage.
Why does that matter?
Research suggests these specialised peptides may support the production of important cartilage matrix components including:
- Type II Collagen
- Aggrecan
- Elastin
Together these components contribute to the structure, resilience and flexibility of healthy cartilage.
What particularly caught our attention wasn't simply the laboratory research.
Published canine research investigated these bioactive collagen peptides using both owner assessments and objective force-plate gait analysis to evaluate mobility over a 12-week period.
It's this combination of biological research and canine studies that led us to include advanced bioactive collagen peptides in the latest evolution of KineticFlex Ultra.
How Advanced Bioactive Collagen Peptides Work
Emerging research suggests specialised bioactive collagen peptides interact with the cells responsible for maintaining healthy cartilage.

Every ingredient has a purpose.
We believe you should know exactly what your dog receives every day. That's why we're transparent about our ingredient inclusion rates and the role each ingredient plays within the KineticFlex Ultra formula.
Explore the Science Behind KineticFlex Ultra
We believe owners should understand why we've chosen every ingredient. If you'd like to explore the science and the thinking behind our latest formulation, we've written two in-depth articles explaining the evidence behind our decision.
š Why We Upgraded the Collagen
Discover why we reviewed the latest evidence and decided to update the KineticFlex Ultra formulation with Advanced Bioactive Collagen Peptides.
Read the Evidence Review āš§¬ Bioactive vs Standard Collagen
Learn the difference between standard hydrolysed collagen and Advanced Bioactive Collagen Peptides, and why they shouldn't be considered the same ingredient.
Compare the Two āWe don't ask you to simply trust our decisions.
We believe in explaining them. That's why we openly share the evidence, the reasoning behind our formulations, and why every ingredient has earned its place.
Why We Started KineticFlex Ultra
KineticFlex Ultra didn't begin in a laboratory.
It began with one dog.
Like so many owners, we searched for a joint supplement that genuinely reflected the science. We found plenty of products making impressive claims, but very few explaining why every ingredient had been chosen.
So we decided to create the formula we wanted for our own dog.
We didn't follow trends.
We followed the science.
That philosophy continues today.
As new research emerges, we continually review our formulations, selecting ingredients because they have a scientific rationale, not because they're fashionable.
It's why KineticFlex Ultra continues to evolve. And it's why every ingredient has earned its place in the formula.
Why We Believe In Multi-Ingredient Formulations
Healthy movement depends on an entire biological systemānot a single ingredient.
Every stride your dog takes relies on healthy cartilage, synovial fluid, connective tissues, ligaments, tendons, muscles and bone working together. That's why we don't believe mobility nutrition should focus on just one ingredient.
Instead, KineticFlex Ultra combines carefully selected ingredients that each have a specific purpose within the overall formulation. Together, they create a comprehensive nutritional approach designed to support the structures involved in healthy movement.
š¦“ Cartilage
Supports the resilient tissue that cushions joints and helps movement remain smooth.
š§ Synovial Fluid
Supports the natural lubrication that allows joints to move freely.
š§¬ Connective Tissues
Includes the structures that help support stability, flexibility and movement.
š Healthy Movement
Because healthy movement is the result of many structures working togetherānot one ingredient acting alone.
One formula. Multiple purposes.
Every ingredient within KineticFlex Ultra has been selected because it contributes to the overall formulation. We don't formulate around trends or single "hero" ingredientsāwe formulate around the biology of healthy movement.
Build Your Dog's Complete Mobility Plan
Healthy movement isn't supported by a single ingredientāor even a single product. That's why we've developed complementary nutritional systems designed to work alongside KineticFlex Ultra.
The Dual Support System
Designed for owners looking to support multiple aspects of mobility by combining KineticFlex Ultra with targeted nutritional support.
- ā Joint support
- ā Digestive support
- ā Everyday mobility nutrition
The Comfort System
For dogs requiring additional nutritional support alongside their daily mobility routine.
- ā Enhanced mobility support
- ā Designed to complement Ultra
- ā Simple daily routine
Every dog is different. That's why we believe mobility support should be tailored to the individual rather than relying on a one-size-fits-all approach.
The Kater4K9 Promise
When you choose KineticFlex Ultra, you're choosing far more than a joint supplement.
Evidence Before Trends
We continually review emerging research and evolve our formulations when the science supports doing so.
Complete Transparency
We believe owners should know exactly what they're feeding, which is why we openly publish our ingredient inclusion rates.
Quality Without Compromise
Premium ingredients. Carefully sourced. Purposefully selected. Every ingredient earns its place.
Every ingredient has a purpose.
Because your dog deserves a formula that's built on thoughtful, synergistic formulation, not fashionable ingredients, included at levels that are not supported by evidence.
Science First. Dogs First. Always.

Frequently Asked Questions
Everything you need to know about KineticFlex Ultra.
What makes KineticFlex Ultra different from other joint supplements?
KineticFlex Ultra has been formulated around the biology of healthy movement rather than a single "hero" ingredient. Every ingredient has been selected because it contributes to the overall formulation, combining Advanced Bioactive Collagen Peptides with glucosamine, MSM, Green Lipped Mussel, hyaluronic acid, chondroitin and carefully selected supporting nutrients. We believe thoughtful formulation is more important than simply chasing headline ingredient amounts.
What type of collagen does KineticFlex Ultra contain?
KineticFlex Ultra contains Advanced Bioactive Collagen Peptides (hydrolysed collagen). These specialised collagen peptides were selected because emerging research has investigated their interaction with chondrocytesāthe specialised cells responsible for maintaining healthy cartilage.
Does KineticFlex Ultra contain Type II collagen?
No. KineticFlex Ultra does not contain Type II collagen as an ingredient. Instead, it contains Advanced Bioactive Collagen Peptides that have been studied for their potential role in supporting the production of important cartilage matrix components, including Type II collagen, aggrecan and elastin within healthy cartilage.
Why did you change the collagen?
We continually review emerging scientific research and update our formulations when we believe new evidence supports doing so. After reviewing the research into Advanced Bioactive Collagen Peptides and canine mobility, we felt they deserved a place in the latest evolution of KineticFlex Ultra.
Why doesn't KineticFlex Ultra simply contain more glucosamine?
We believe it's important to look at the complete formulation rather than focusing on a single ingredient. Current research does not clearly demonstrate that simply increasing the amount of glucosamine results in a better mobility supplement. Instead, KineticFlex Ultra combines multiple carefully selected ingredients that each contribute to the overall formulation.
Can KineticFlex Ultra be given alongside medication?
KineticFlex Ultra is a complementary feed. If your dog is receiving medication or veterinary treatment, we recommend discussing any new supplement with your veterinary surgeon before introducing it.
Is KineticFlex Ultra suitable for all breeds and sizes?
Yes. KineticFlex Ultra has been formulated for dogs of all breeds and sizes. Feeding amounts are adjusted according to your dog's body weight.
Can I use KineticFlex Ultra alongside other Kater4K9 supplements?
Yes. Many owners choose to combine KineticFlex Ultra with other Kater4K9 products as part of their dog's daily nutritional routine. If you're unsure which combination is most appropriate for your dog, we're always happy to help.
Why do you publish your ingredient inclusion rates?
Because we believe complete transparency matters. We think every owner deserves to know exactly what their dog receives in every daily serving, which is why we openly publish our ingredient inclusion rates.
How long should my dog stay on KineticFlex Ultra?
KineticFlex Ultra is designed to become part of your dog's daily nutritional routine. Joint nutrition isn't about a quick fixāit's about providing consistent nutritional support as part of a long-term approach to healthy movement.
Why don't you make stronger claims about what KineticFlex Ultra can do?
As a complementary feed, we believe it's important to communicate responsibly. Rather than making exaggerated claims, we focus on explaining the science behind our formulation, the quality of our ingredients and why each one has been selected. We believe trust is built through transparency, not hype.

I rescued a 9 year old bordercollie that someone got rid of because he was getting old and going to start costing money.. š”I started giving him Yumove and Galaprant and I took him to hydrotherapy and the lady recommended KATER4K9, within 4 weeks I saw a huge difference and many of my friends that I recommended it to also have seen massive changes in their older dogs.. yes you cannot stop old age but you can make it easier and less painful for them, donāt wait till you see them suffering start as early as you can!! My dog is now 12 and still running and enjoying life and his walks
Donāt wait get this now ššš»šš»
Thank you Elaine for your lovely review.
I'm so happy your collie now has the best home ā¤ļø
Have my almost 12 year old girl on this and sheās still running around like a puppy with her much younger housemates
This is great for our old husky and bulldog. Yumove stopped being of much use to them in their later years but KineticFlex has given them a new lease of life.
My young collie has been on joint supplements since she was one as she has multiple joint issues.
I've moved her to Kineticflex ultra as recommended by her nutritionist as it covers more of what she needs in one product.
We have had a lot of problems getting her to eat anything let alone adding anything to her food so any additions need to be gradually introduced, the powder is quite strong smelling so I was expecting her to refuse to accept it but it only took a week of slowly increasing the amount added for her to happily have the full dose for her weight.
The ingredients mix and levels are excellent so I'm confident that she is getting the best product for her wonkyness.
Excellent joint support. Good value & easy to administer. My old lab has been on Kinetiflex for a number of years but as heās nearly 12 & still picking up so Iāve upgraded him to the ultra
