If you train hard, compete, or simply want to know exactly what you're putting in your body, one question matters more than any label claim: can I trust what's in this tub?
That's why we're proud to say that Cortaflex Ultra Joint carries the Informed Sport certification, the global "We Test, You Trust" quality assurance programme for sports supplements.
What is Informed Sport?
Informed Sport is a certification programme that tests supplements and their ingredients for substances banned in sport. It's run by LGC, a world-leading independent testing laboratory with decades of anti-doping experience. Products that carry the logo have been tested at a laboratory accredited to the highest international standards, and the manufacturing sites are audited for good practice.
Why it matters for a joint supplement
Supplements aren't always as clean as they claim. Contamination can happen anywhere in the supply chain: shared equipment, raw material cross-contamination, or poor handling. Even a trace of a banned substance can lead to a positive drug test, and "I didn't know it was in there" is not a defence in sport.
For athletes, that risk is real. For everyone else, the same testing gives you added confidence that what's on the label is what's in the tub.
Tested every batch
The key phrase on our badge is every batch. Certification isn't a one-off tick. Each production batch of Cortaflex Ultra Joint is tested before it's released, so the quality you get this month is the quality you get next month.
Who benefits?
- Competitive athletes in drug-tested sports who need joint support without risking their eligibility
- Weekend warriors, runners and gym-goers who want a high-quality product they can trust
- Anyone who's careful about what they take, because clean, tested and transparent is simply better
