Don't let an old ACL injury dictate your life.
Up to 50% of ACL injuries lead to osteoarthritis. Type II collagen is backed by 17 clinical trials and developed specifically to support joint flexibility and function — helping you maintain joint comfort and stay active.

Your ACL healed. Your cartilage didn't get the memo.
ACL injuries don't just damage a ligament. They set off a chain reaction inside the joint that can continue for years after the original injury heals.
- Post-traumatic osteoarthritis can develop years after the original ACL tear
- Surgical repair reduces instability but doesn't eliminate OA risk
- Most joint supplements were built for age-related wear and tear — not post-ACL knees
of ACL injuries progress to osteoarthritis — often within 10–15 years of the original injury.

One ingredient. A completely different mechanism.
UC-II® undenatured type II collagen doesn't work the way most joint supplements do. It actively retrains the immune response that's breaking your cartilage down.
and counting
Oral tolerance mechanism
When a small amount of native type II collagen is presented to Peyer's patches in the gut, regulatory T-cells are activated that travel to your joints and suppress the immune response attacking your cartilage.
Clinically outperforms glucosamine
In a head-to-head trial, 40mg of UC-II® outperformed 1500mg glucosamine + 1200mg chondroitin on pain and joint function. A 2025 meta-analysis of 17 RCTs confirmed the results.
Built for post-ACL knees
Post-traumatic osteoarthritis involves both structural cartilage damage and an immune-mediated inflammatory cascade. UC-II®'s oral tolerance mechanism directly addresses this cascade.
"I tore my ACL years ago. The surgery went fine. The physio went fine. But my knee never quite went back to what it was — and nobody told me there was a reason for that."
