Created for Dogs like Isla, for when the walks got shorter and movement became harder.
As dogs age or stay active, you may start to notice stiffness, slower movement, or hesitation where there wasn’t before.
We saw this with our own dog, Isla and it’s what led us to create KineticFlex, using vey carefully selected, high quality ingredients to support long-term mobility and comfort.
Because every dog deserves to stay active, happy, and by your side for longer.
Why KineticFlex?
Healthy movement depends on far more than joints alone.
Every step your dog takes relies on healthy cartilage, connective tissues, synovial fluid, ligaments, tendons and bone working together as one highly specialised system.
That's why KineticFlex was never designed around a single "hero" ingredient. Instead, we've carefully selected eleven premium ingredients that each contribute to a thoughtfully balanced mobility formula.
We don't formulate for headlines.
We formulate for healthy movement.
From premium 99% Pure Glucosamine HCL and New Zealand Green Lipped Mussel to Boswellia, MSM and Hyaluronic Acid, every ingredient has been selected because it supports the overall formulation.
Because we believe the best mobility supplements aren't built around trends—they're built around thoughtful formulation.
Why We Believe In Balanced Formulations
Healthy movement depends on biology—not one ingredient.
It's easy to compare supplements by looking at the amount of a single ingredient. While ingredient levels matter, we believe it's the complete formulation that deserves the greatest attention.
Current published research does not clearly demonstrate that simply increasing glucosamine levels automatically creates a better mobility supplement. That's why we focus on how carefully selected ingredients work together within the overall formulation rather than chasing larger numbers on a label. Read our article in the knowledge hub that askes the question, Does more glucosamine make for a better supplement? The answer might surprise you!
Every ingredient has a purpose.
Every ingredient earns its place.
That philosophy has guided KineticFlex from the very beginning and continues to shape every formulation we create.
Inside Every Daily Serving
Complete transparency matters.
The amounts below are based on the recommended daily serving (2 scoops) for a medium-sized dog. Feeding amounts vary according to body weight.
MSM (Methylsulphonylmethane)
838mg
Included as the cornerstone of the KineticFlex formulation alongside glucosamine, Green Lipped Mussel and chondroitin as part of our balanced approach to mobility nutrition.
99% Pure Glucosamine HCL
500mg
Produced through fermentation and selected for its exceptional purity and consistency to provide nutritional support for healthy cartilage and connective tissues. Included at an evidence led amount, as research does not consistently show that increasing glucosamine beyond appropriate levels provides an additional benefit, as absorption becomes limited. That’s why we focus on a balanced, evidence led formulation rather than simply increasing the amount. Learn more in our article:
Green Lipped Mussel (5:1)
300mg
Sourced from New Zealand, this Green Lipped Mussel is concentrated making it 5 x stronger than standard preporations.

Everything you need to know about KineticFlex and our approach to science-led mobility nutrition.
KineticFlex was developed around one simple philosophy: every ingredient should earn its place. Rather than focusing on a single "hero" ingredient, we've carefully balanced premium ingredients that work together to support the structures involved in healthy movement.
We use 500mg of 99% pure Glucosamine HCL per medium dog daily serving because we believe formulation quality is more important than simply chasing larger numbers. Current published research does not clearly demonstrate that increasing glucosamine alone creates a better mobility supplement, so we focus on the complete formulation rather than one headline ingredient.
