Indicators of Reduced Joint Function
These changes are commonly associated with age-related or activity-related decline in joint function. Use Targeted nutritional support to help maintain mobility
Multi-Pathway Joint Support
KineticFlex Ultra is formulated to support multiple physiological pathways involved in joint health, rather than relying on a single ingredient approach.
Glucosamine HCl and chondroitin contribute to the structural components of cartilage.
Hyaluronic acid supports synovial fluid function within the joint.
Collagen peptides support tendons, ligaments and overall joint stability.
Boswellia extract helps maintain a normal inflammatory response.
Formulation Quality Comparison
Joint supplements may appear similar on the label. In practice, formulation quality is determined by ingredient purity, standardisation, sourcing, and inclusion levels — not simply ingredient presence.
| Component | Typical Market Standard | KineticFlex Ultra Specification |
|---|---|---|
| Glucosamine | Variable purity, often blended or diluted forms | 99% pure glucosamine HCl |
| Collagen | Minimal inclusion or not present | High-dose collagen peptides (5g+ per serving) |
| Boswellia | Unstandardised raw powder | Standardised extract (65% boswellic acids) |
| Hyaluronic Acid | Low-grade forms with limited active content |
High-spec hyaluronic acid (≥40% glucuronic acid) Indicates high structural integrity and functional quality |
| Green Lipped Mussel (GLM) | Generic GLM with inconsistent omega-3 levels |
GlycOmega® (New Zealand sourced) Ultra high Omega-3 yield + natural chondroitin (5:1 concentration) |
| Formulation Approach | Single or limited ingredient focus | 12 active ingredients targeting multiple pathways |
| Ingredient Transparency | Partial or unclear labelling | Fully disclosed composition and dosages |
The effectiveness of a joint supplement is influenced by ingredient form, purity, and dosage. Products with similar labels can differ significantly in formulation quality and functional value.
Formulation Integrity Statement:
KineticFlex Ultra is developed using defined-purity compounds, standardised extracts, and clinically relevant inclusion levels prioritising formulation quality over label-driven ingredient listing.

Frequently Asked Questions

- Large dogs: 3 scoops daily

Can this be given with other supplements?
KineticFlex is designed to be mixed easily with your dog’s regular food. Many owners combine it with other nutritional supplements, but if your dog is taking medication or multiple supplements, it’s best to check with your veterinary surgeon before introducing anything new.
Is this suitable for all breeds and sizes?
Yes. KineticFlex is formulated for dogs of all breeds and sizes. Feeding amounts can be adjusted based on your dog’s weight, age, and activity level, making it suitable for everything from small companions to large breeds.
What collagen type do you use?
KineticFlex Ultra goes even further by support connective tissue such as tendons, ligaments, and bone. To do that we need Type I collagen. We source ours from hydrolysed marine peptides. Its low molecular weight ensures high bioavailability, delivering key amino acids (glycine, proline, hydroxyproline) that support connective tissue in tendons, ligaments, and bone. Clinical studies show these peptides are efficiently absorbed and reach peripheral tissues, making marine collagen a reliable source for structural support.

I rescued a 9 year old bordercollie that someone got rid of because he was getting old and going to start costing money.. 😡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, don’t 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
Don’t wait get this now 🙏👍🏻👍🏻
Thank you Elaine for your lovely review.
I'm so happy your collie now has the best home ❤️
Have my almost 12 year old girl on this and she’s still running around like a puppy with her much younger housemates
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 he’s nearly 12 & still picking up so I’ve upgraded him to the ultra
Bought this for my older boys to give them a bit of an extra boost. Fantastic joint support
