Cartilage repair substrate. Joint cushioning. The base of every credible joint study.
Pairs with glucosamine to slow cartilage breakdown. Without it the protocol leaks.
Trains the immune system to stop attacking joint tissue. Our 40 mg exceeds the 10 mg dose used in the published dog trials.
Sulfur source for connective tissue. Helps reduce morning stiffness in older dogs.
Synovial fluid lubrication. The shock absorber inside the joint capsule.
Omega-3 and ETA fatty acids. Hits the same inflammation pathway as fish oil but tighter for joints.
Six things we will not compromise on. The line that follows is everything you can take to your vet.
Most brands end the story at Day 90. The studies don't. Peak benefit lands at Day 120 and holds at Day 150. Stop dosing and the gain fades within 30 days.

No five-star floor. No filter. These are the reviews owners actually wrote, including the ones that took a while to flip.
Took two months. Day 60 my collie started taking the stairs without the hesitation he used to have. He used to wait at the bottom and look up. Now he just goes.
Standard mature lab stuff: stiffness in the morning, slow off her bed. Eight weeks in she's getting up the same way she did at six. We've kept her on it since.
He's a working dog and started losing push from the back end this winter. Vet flagged early hip stuff. We're three months in and the trot is back. Long way to go but it's there.
Honest review. First six weeks I wasn't sure. Around week 10 something flipped. She started jumping up onto the bench again. Whatever the science is doing, it's doing something.
Was on Yumove and Metacam scripts. Vet was fine with us trying this in parallel. Six months later we're off the Metacam most days. Daily WoofCore plus a walk. That's the protocol now.
Expensive next to the £12 chews at the pet shop. Reading the actual mg on the label is why we made the switch. She eats them straight off the floor like a treat, which helps.
Four early-access subscribers. Updates from week 11. The protocol works on field-report time, not before-and-after time.
Day 78Martha & Bruno
Back on the stairs without the morning pause. He used to wait at the bottom for a beat. Now he just goes.

Garden runs are back. He stopped doing them in the autumn. The trot is the same one he had at six.

Day 84Megan & Tiber
Same as my § 05 write-up but quieter to type. Still on it. Still climbing the stairs. Haven't refilled the Metacam.
